Issue
The A and B Channels used to communicate to Sublan devices need to interface with FOI (Fiber Optic Interface) devices, but not sure what speed it communicates on or what setting it should be.
Environment
I/NET Seven Controller Lan on a 7793 MCI.
Cause
Setting up a 7793 Controller to communicate to a FOI.
Resolution
On a 7793 MCI, there are several ports that are used for communication to various devices. These ports are:
- A standard synchronous RS485 controller LAN Port.
- Two standard asynchronous RS485 sub-LAN Ports.
- Two asynchronous RS232 ports, one used for the HHC Console and the other for Direct Connect to a PC.
- An optional plug on-board with an RS232 synchronous connection used for an external modem.
