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.
