lines can also operate at up to 38,400 baud (57,600 with the optional
9.216-MHz clock upgrade).
A second RS-232 port can be configured as a substitute for the RS-422/
RS-485 port by changing board jumpers, but it will have no handshaking
lines. Pins 3-4 and 5-6 on Header 8 are connected to enable RS-422/
RS-485 communications. Remove these jumpers and connect Pins 1-2 on
Header 8 to enable the second RS-232 output. The RS-232 output pin will
be TX-, and the input will be RX-. RX+ must be tied to ground. The
jumper arrangements are shown in Figure 3-14.
The PK2100 has a 26-pin connection to allow access to Z-Worlds
PLCBus expansion bus for customer-designed devices or Z-Worlds
PLCBus expansion devices.
