Set Chain Port Input

The TSU 120 can be configured from the chain port input when T-WATCH Pro, SNMP, or the terminal interface are being used. In this case, the chain port baud rate must also be selected.

Chain-In (PC)

The unit can be controlled from an external PC connected directly or via modem to the chain-in port. When using chain- in, the selection of the chain-in port baud rate from 9600 (fac- tory default), 1200, 2400, 19200, or 38400 must be made using the UNIT CONFIGURATION MENU. See Unit Menu on page 5-12for details.

Unless locked out externally, the front panel can also control the unit.

Chain-in/Chain Out

TSU 120 units and other TSUs can be linked together to form a chain. Figure 2-4provides an example of a chain-in arrange- ment with a PC or a modem. The first TSU 120 in the chain receives controlling input from the PC or modem.

Figure 2-4. Example of Chain-in

Subsequent TSUs in the chain are in a position to intake infor- mation from another TSU. This in-taking of information from another TSU in the chain is identified as chain-in. The baud rate for the chained units must match that of the first unit.

Unless locked out externally, the front panel can also control the unit.
