Serial Communication
Two serial channels support asynchronous communication at baud rates
from 300 bps to 57,600 bps. Serial communication provides a simple and
robust means for networking controllers and other devices.
Figure 3-14 illustrates the configuration of the OP7100 serial channels.
Figure 3-14. Serial Channels
The factory default configuration for the OP7100 is for one 5-wire RS-232
port (with RTS and CTS) and one half-duplex RS-485 port. An RS-485
channel can provide half-duplex asynchronous communication over
twisted-pair wires for distances up to 3 km. Two other configurations,
shown in Figure 3-14, are one 3-wire RS-232/one RS-485, and two 3-wire
RS-232. The configurations are set with jumpers on header JP3.
