Port Configuration
The 485DSS has a RS-485/422 port and a RS-232 port. The RS-
485/422 signals are on terminal blocks. Table 1 shows you the
pinouts and Figure 2 shows you the location of the terminal blocks.
The RS-232 signal, in the DTE configuration, connects to a DB25
male connector. Table 2 shows you the RS-232 pinouts.
RS-485/422 Port
The RS-485 port on the 485DSS receives and transmits data to
and from the RS-485 network. The RS-485 port has a balanced
differential line driver and receiver. RS-485 allows up to 32 driver and
receiver pairs to share a two-wire party line network. This port will
operate on a 4-wire network and is compatible with RS-422 devices.
Refer to B&B Electronics' free RS-422/485 Application Note for more
