How to review or copy a stored recording

To review a stored recording, first enter the Service Functions dialog by tapping the Tap to access service functions field during system start up. (Finish possible ongoing recordings by selecting Start New if asked.) Then select the button Manage Recordings button, second from the left, to enter the Manage Recordings dialog.

To select recordings stored on the temporary storage on the internal disk, select the Internal Storage button. To be able to view recordings stored on a USB storage device, the device must first be plugged in, and then the USB Storage button be selected. Note that if no USB storage device is connected, the USB Storage button will be disabled. It is also possible to review the backup copies of the recordings that have already been transferred to a final storage media. This is done by selecting the Backup Storage button.

In the Manage Recordings dialog, the recordings will be listed in alphabetical order by recording name, which is practically the same as chronological order. Start time and date, and patient name for each recording will also be listed as an aid for the user.

To review a recording, highlight it by tapping the screen or use the up/down arrows on the screen or keyboard, and then select the Review Recording button or press return on the keyboard to load it. The PgUp/PgDown alt. Home/End keys on the keyboard can also be used to manoeuvre in the list. After a recording have been reviewed, the Service Functions dialog will be displayed.

To copy a recording from either the Internal Storage or Backup Storage, first connect your USB storage device, which does not need to be prepared for final storage. Wait for the Copy to USB button to become enabled. At the same time, the dialog will display the recordings on the USB storage. Enter either the Internal Storage view or the Backup Storage view depending on where the recording to be copied is located. Highlight the recording and then select the Copy to USB button. A confirmation dialog will be displayed before the recording is copied.

How to calibrate the touchscreen

To calibrate the touchscreen, enter the Touchscreen Calibration dialog. This can be done either by selecting the Calibrate Touch button in the Maintenance Functions dialog as described above, or by touching the bottom left field stating Tap to calibrate touchscreen during start up. As with the service functions, the calibration dialog cannot be accessed while a temporarily ended recording is on the internal disk. In occurring cases, end the recording first by selecting the Start New button in the Continue Recording dialog.

If the screen is so poorly calibrated that none of the above methods can be used to access the Touchscreen calibration dialog, a PS/2 compatible mouse can be used as control device, so that the calibration dialog can be reached. Note that the mouse must then be plugged into the mouse PS/2 connector before the system is started, as the system will fail to detect it otherwise. Use the mouse to access the calibration dialog using the methods above. The left mouse button emulates touching the screen at the current mouse pointer position. Remember that the mouse cannot be used for the actual calibration.

Calibrating the touchscreen is done by touching a number of targets on the screen, preferably by a pointy object. The first two touches are used to calculate the boundaries of the screen, and the last two touches are used to verify these calculated boundaries. If the last touches are inconsistent with the first ones, the calibration is considered too inaccurate, and the user is asked to start the process over again. If the calibration is successful, the calculated base coordinates are stored in the counter information file, and the calibration dialog disappears.

To leave the Touchscreen Calibration dialog without having to re-calibrate the screen, use the escape key on the keyboard. There is also a timeout that exits the calibration dialog after 30 seconds of inactivity.

Note: If the calibration routine continues to fail, the hardware might be assembled incorrectly. In this case, inspect the connection between the touchscreen controller device and the actual touchscreen.

How to change the system time

To set the system time, first enter the Service Functions dialog by tapping the Tap to access service functions field during system start up. (Finish possible ongoing recordings by selecting Start New if asked.) Then select the third button from the left, Set Time, to enter the Time and Date dialog.

To change the current year, month, day, hour or minute, select the appropriate unit among the five left-most buttons in the dialog, and then use the Increase/Decrease buttons to alter the selected unit. When done, exit the dialog by selecting the Exit button or pressing escape on the keyboard.

Note that the STAN S31 does not adjust the system clock automatically for daylight savings time changes. To adapt to daylight savings time changes, the correct time must be set manually by using this dialog.

How to transfer recordings to USB storage media

The following apply when STORAGE_DEVICE is set to USB Storage.

Anytime when the STAN is started, plug a prepared USB storage device into any of the two available USB connectors. It may be easier to do this with an USB extension cable. Note that it is possible to do this during an ongoing recording, without having to end it first.

When STAN identifies a prepared USB storage device, a confirmation dialog will first ask whether to start transfer recordings. If you select Yes, all recordings stored temporarily on STAN will be transferred. This may take some time, depending on the number of recordings being transferred and the length of each recording. During the transfer process, a dialog will be visible on the screen, showing the progress in number of recordings and a progress bar.

It is important not to remove the USB storage media while the transfer is running. To interrupt an ongoing transfer, press the Cancel button in the transfer dialog first.

When the transfer is complete, the dialog will remain for 5 seconds, and then the operation of the STAN device returns to normal. It is then safe to remove the storage media.

How to prepare a USB Storage device for recording transfer

As mentioned above, USB devices that are to be used for transfer must be prepared through a special process. The purpose of this is to provide protection against unauthorised people taking recordings from a STAN unit, intentionally or by mistake by plugging a memory stick, music player etc.. The preparation process only has to be performed once for a new storage device, before the first time it is used. Note that the act of preparing a storage device does not format it or delete any existing files. Before they can be used by STAN, all USB devices must be formatted with either the FAT (e.g. MS-DOS) or FAT32 file system.

To prepare a USB disk for recording transfer, start the STAN unit. After a short while, a rectangular area named Tap to access service functions will be visible in the lower right and left corner. Within three seconds, tap (touch and release) the rectangular area. This will open a Service Functions dialog with four options. (Finish possible ongoing recordings by selecting Start New if asked.)

In the Service Functions dialog, select the Change Settings button to open the System Settings dialog, then the Maintenance Functions button to open the Maintenance Functions dialog, and then the Prepare Storage Device button to open the Prepare Storage dialog.

Plug the USB storage device to be prepared into any of the two available USB connectors. Wait for STAN to detect the device and enable the Prepare USB Device button. Select the button and then confirm by selecting Yes in the confirmation dialog that follows. Another confirmation dialog will tell whether the operation was successful or not. After a couple of seconds, any stored recordings will be transferred to the newly prepared device, as described above. The device can then be safely removed and from here on be used as a storage device on any STAN S31 unit.

How to update the system software

Software updates are generally supplied through the local distributor. Enclosed with each update is a detailed instruction on how to perform the update, and documentation relating to new and changed functions for the software. Contact your local distributor for further assistance.

How to configure STAN S31 for IP networking

First connect the STAN unit physically to the network using a TP (i.e. twisted pair) network cable with RJ-45 connectors. Ensure that the correct cabling is used and that a CNK 101 003 Ethernet Isolation Box is connected between the STAN and the network. If the STAN is to be directly connected to the network port of a printer, without going e.g. through a switch or a network HUB, the Rx/Tx signals of the cable needs to be crossed.

Start the STAN and enter the System Settings dialog by first tapping the Tap to access service functions field during system start up (finish possible ongoing recordings by selecting Start New if asked), and then selecting the Change Settings button.

If the network has a DHCP server, and that is to be used, change the USE_DHCP setting to Yes. The DHCP server will supply the STAN with a machine IP address, subnet mask, and possibly also a DNS server and gateway if that is supported on the local network.

If a DHCP server is not to be used, ensure the USE_DHCP setting is set to No. Then set the MACHINE_IP to the fixed IP address, and the MACHINE_IP_MASK to an appropriate subnet mask. If DNS name resolution is to be used, also set the DNS_IP. If communication through a gateway is required, e.g. if printers are localised on another subnet, GATEWAY_IP also needs to be set.

Note that the default MACHINE_IP, 127.0.0.1, stands for localhost, which cannot be used if communicating with other computers or servers on a network.

Select the System Status menu button and verify the settings in the External Status view of the System Status dialog.

In the Network field, the network configuration is stated in terms of IP addresses. After each IP address, the current status for the connection is stated as Offline (meaning that the network is temporarily offline), Online (that the network node could be reached using the ping protocol), or Inaccessible (meaning that the network is online, but there is no reply over the ICMP Echo (i.e. ping) protocol). Wait means that the network is being reconfigured.

If a DHCP server is configured, IP Address in the Network field should display an IP address with four numbers separated by dots. Automatic configuration can take several minutes each time the setting is being changed, depending on the DHCP server.

If a DHCP server is not being used, the connection can be verified by looking at the status of a configured DNS Server, Gateway or page printer if any configured. The status should then say Online. If none of those are configured, try to verify using the ping command from another computer on the network.

How to configure STAN S31 for network printing

Ensure that the printer supports the PCL-5 language, that it has a network connection and supports the LPD (Line Printer Daemon) network protocol. Optionally, the printer can be connected through a network printer server that supports LPD.

Configure STAN for IP networking as described above. If STAN and the printer are to be connected locally using a crossed cable, we recommend that both STAN and printer are configured with fixed IP addresses in the 192.168.0.x series (e.g. 192.168.0.1 for STAN and 192.168.0.2 for the printer), with subnet mask 255.255.255.0. Remember that for this configuration, a CNK 101 003 Ethernet Isolation Box is needed between STAN S31 and the printer.

Set any of the three PAGEPRINTER_X_ COMMTYPE settings to Network Printer.

Then set the corresponding PAGEPRINTER_X_IPADDRESS to the printer’s IP address on the network, or its DNS network name. Note that if a DNS name is used, a DNS server needs to be configured, either automatically through the use of a DHCP server, or manually using the DNS_IP setting. If the printer is not within the same subnet as the STAN, a gateway must be configured, either through a DHCP server of manually using the GATEWAY_IP setting.

If a printer server is used, or if the printer has multiple queues, set the corresponding PAGEPRINTER_X_QUEUENAME to the LPD queuename for the specific printer/queue.

If several printers are configured, it might be a good idea to set the corresponding PAGEPRINTER_X_NAME to something the users can relate to, e.g. Expedition, or Brother. If this is left blank, Printer <x> will be used instead when referring to the printer in the GUI.

Enter the System Status dialog by selecting the System Status button. Select the External Devices view.

Ensure that the printer is reachable by STAN by checking that the status notification in the Printers field states Online. If Inaccessible is stated instead, it means that the printer does not reply to ICMP Echo requests from the STAN unit, and further troubleshooting is needed. Note that a firewall installed on the network between STAN and the printer may block ICMP packets but still allow print jobs to get through. Printing a test page by selecting Test Print gives a definite answer.

Make a test printout, and adjust the corresponding PAGEPRINTER_X_ GRAYLEVEL if necessary. The default setting, Normal, is good for most printers. If the users feel that the printout is too dark or too bright, the setting might need to be adjusted.

How to configure STAN S31 for CMS communication

Connect the central monitoring system physically to the COM2 serial port of the STAN unit using adequate cabling, including a CNK 101 005 Brutech RS232 Isolator. Then start the STAN system and enter the Service Settings dialog by first tapping the Tap to access service functions field during system start up. (Finish possible ongoing recordings by selecting Start New if asked.) Then select the button Change Settings button.

Scroll down to the SURVEILLANCE_PROTOCOL setting, and change it to reflect the Central Monitoring system being used. For communication with central monitoring systems that support ST information, use the STAN Protocol (COM2) setting. For communication with most compatible monitoring systems that do not support ST information, use the CTG Protocol (COM2) setting. Certain third party systems will require the CTG Extended Protocol (COM2) setting.

Leave the Service Settings dialog using the Exit button, and start a new recording by selecting the Start New button in the Service Functions dialog.

In the bottom left corner of the recording screen, inspect the state of the Central Monitoring indicator. This is green when communication is established with a central monitoring system and orange when there is no communication or when the communication is otherwise malfunctioning. It is grey when no central monitoring is configured. If the indicator is orange, review the troubleshooting section in the service manual.

How to configure STAN S31 for network recording storage

First decide what protocol and server type to use. FTP and HTTP/WebDAV are the easiest to implement, while HTTP/POST is intended for more advanced server applications, e.g. when the recording file is to be added to a digital patient record or similar.Install the server application and decide what kind of authorisation is to be used. Although anonymous access is supported, Neoventa recommends that, when not using anonymous access, a unique account is created on the server for the STAN devices, or that “write-only” anonymous access is used. In rare cases, servers may not allow the same user holding several sessions open at the same time, it which case it is advisable to have one account for each STAN unit. Please note that for both FTP and HTTP, the user name and password are sent in clear text over the network. They are also stored, in scrambled form, on the STAN system disk. It is recommended that you do not use a privileged network account (e.g. “root”, ”administrator”) for authenticating STAN.

Neoventa also recommends the use of some automated backup for the disk or folders where the server stores the recording data.

Configure STAN for IP networking as described above, and validate the network settings using the System Status dialog.

Set the STORAGE_DEVICE setting to match the server type, either FTP, HTTP/ WebDAV or HTTP/POST.Set the NETWORK_STORAGE_URL to point out the network node where the server is located, e.g. ftp://192.168.0.0 (or http://192.168.0.0) if the server is located on the fixed IP address 192.168.0.0. If DNS (Domain Name System) is configured, it is recommended to use the name of the server instead of the IP address, e.g. ftp://example.com or http://example.com. If the recordings are to be placed in a specific sub-folder on the server, this can also be specified in the URL, e.g. ftp://example.com/STAN/ or http://example.com/STAN/, if the recordings are to be placed in sub-folder STAN.Then specify the user account that STAN shall use when logging on to the server, by setting the NETWORK_STORAGE_USERNAME and NETWORK_ STORAGE_PASSWORD settings. If these are left empty, STAN will use “anonymous” for username and “User@STAN” for password when authenticating against an FTP server.

To validate the network storage settings, select the Network Storage Control button to enter the Network Storage Control dialog. Make sure the network cable is properly attached, and then select the Test button. STAN then tries to connect to the defined server, and tests different types of operations that are needed to be able to store recordings. In order for Network Storage to function properly, STAN must have permission to create sub folders and create new files on the server. During a test, a folder (Safe_to_delete_NNNN) is created and a text file (Safe_to_delete_ NNNN.txt) is uploaded to this folder. You may delete these from the server after the test.

If the configuration is correct, STAN will upload finished recordings in chronological order as a background task during ongoing recordings. It is also possible to start the storage procedure by selecting the Start Storage button in the Network Storage Control dialog.
