Using Cherry eHealth Card Terminal ST-1506 in USB RNDIS Mode with IGEL OS

If you, for example, do not have a free network socket, you can operate your Cherry eHealth Card Terminal ST-1506 via an endpoint in USB RNDIS (Remote Network Driver Interface Specification) mode. In this case, IGEL OS endpoint acts as a NAT router. The card terminal will use the network interface of your IGEL OS device.

Requirements

• IGEL OS 11.08.100 or higher

• Cherry ST-1506 must have a static IP configuration  

Configuration on Your Cherry ST-1506

1. Connect your card terminal to the IGEL OS device.
   

2. In the Menu > Admin Menu, enter your admin PIN.
   

3. Go to Connection > USB Ethernet.
   

4. Activate RNDIS.
   

5. Disable DHCP.
   

6. Configure a static IP address. 
   

7. As Gateway, specify the Host IP address which you configure on your IGEL OS device with the registry key devices.cherry.terminal%.rndis.host_ipaddress (Default: 192.168.42.1). See the instructions below.
   

8. Save the settings.

Configuration on Your IGEL OS Device

Per each card terminal, one instance of the template devices.cherry.terminal%  must be created and configured. By default, none is configured and so the feature is essentially disabled. To add and configure an instance, proceed as follows:

1. In the IGEL Setup or the configuration dialog in the UMS, go to System > Registry > devices > cherry > terminal% and click Add Instance.
   

   

   
   For the added instance, configure the following:
   

2. For distinguishing purposes if multiple ST-1506 devices are connected, configure the registry key devices.cherry.terminal%.rndis.device_id. It may be left empty if only one card terminal shall be supported.
   Here, you specify:

   • a MAC address of the card terminal (To find it out, you can use, for example, the command ifconfig in the Local Terminals or view it directly on the ST-1506 in the admin menu)
     OR

   • the value of the udev property ID_NET_NAME_PATH (To find it out, you can use, for example, the command udevadm info --export-db| less)

     

     
     

3. Configure the Device IP address:

   Parameter	Device IP address
   Registry	devices.cherry.terminal%.rndis.device_ipaddress
   Type	string
   Value	192.168.42.42 (Default)
   Note	Here, you specify a static IP you have configured on your ST-1506 via the admin menu. You can leave the default value unchanged if you use it also on your ST-1506. If you have multiple ST-1506 devices connected, you must configure a different IP for each card terminal.

4. Configure the Host IP address: 

   Parameter	Host IP address
   Registry	devices.cherry.terminal%.rndis.host_ipaddress
   Type	string
   Value	192.168.42.1 (Default)
   Note	This is the IP address which you must specify as Gateway on your ST-1506 via the admin menu.

   
   

5. If required, configure the following registry keys:

   Parameter	Device TCP port
   Registry	devices.cherry.terminal%.rndis.device_tcpport
   Type	string
   Value	4742 (Default)
   Note	This port on the host will be passed through to the same port on the device.  If you have multiple ST-1506 devices connected, you must configure a different port for each card terminal.

   Parameter	Passed through device UDP port
   Registry	devices.cherry.terminal%.rndis.device_udpport
   Type	string
   Value	4742 (Default)
   Note	This port on the host will be passed through to the same port on the device. If you have multiple ST-1506 devices connected, you must configure a different port for each card terminal.

   Parameter	Host SSL port
   Registry	devices.cherry.terminal%.rndis.host_sslport
   Type	string
   Value	empty (Default)
   Note	This port on the host will be forwarded to the device's port 443. Configure this registry key if you are using a web browser for the remote management of your ST-1506 devices. If you have multiple ST-1506 devices connected, you must configure a different port for each added instance.
