Issue
Gets error message "GCM Not responding" when he attempts to make a connection to a device on the ASD bus under the UNC.
Product Line
TAC IA Series
Environment
- I/A Series R2 UNC
- I/A Series R2 TunnelAX jar file, version 2.301.534a or later
- I/A Series ibsASD jar file, version 2.301.534a or later
- I/A Series G3 Serial Tunnel 2.0 Client
Cause
Misconfiguration of tunnel name
Resolution
Before attempting to configure the AX Tunneling, verify that the correct versions of the R2tunnelAX and ibsAsd jar files have been installed as documented in How to install an I/A Series R2 JAR File.
Tunnel Name in AX Tunnel Client must match the Tunnel Instance name in the ASD Service.
When you add the AxSerialTunnel to the ibsAsdService, the identifier is automatically assigned based on the port defined in the communications configuration of the IbsAsdService itself. This name is displayed under the Status tab of the AxSerialTunnel:
Figure-1
When configuring the "Niagara AX Serial Tunnel 2.0", the following window is displayed.
Figure-2
The tunnel name (See Figure 2) entered in this window must match the port identifier shown in the AxSerial Tunnel definition (See Figure 1). If these identifiers do not match, the Ax Serial Tunnel Client will not be able to connect to the tunnel in the I/A Series R2 station.
NOTE: When installing the I/A Series G3 Serial Tunnel 2.0 Client, no control panel applet is created as with the earlier version of the I/A Series R2 Serial Tunnel Client. To configure the I/A Series G3 Serial Tunnel 2.0 Client, run the program C:\niagara\VserAx\vseraxConfig.exe. If you need to frequently reconfigure this client, you can create a Window Start Menu shortcut or Desktop shortcut pointing to this file.
