Serial Ports
Tropos 6410-XA and 6420-XA routers that are equipped with serial ports can support serial
clients on RS-232 or RS-485 interfaces. The serial port can also be used to power the router.
The router can support the following serial client scenarios. Before installation determine the
installation scenario and the appropriate powering option for that scenario.
TABLE 4
Wired Serial Client Scenario
one RS-232 serial client
two RS-232 serial clients
one RS-485 client
one RS-232 serial client
one RS-485 serial client
The following are the pin assignments for the RJ-45 MGT port when used for serial clients.
