It also can convert an RS-232 device into a receiver node in this point-to-

point circuit.

The configuration for a RECEIVER node is:

SW1-4 TXC Enable RTS/ADC Control for Driver

SW1-6 RXE Enable Receiver always

SW1-5 RTS-D Disable RTS control

SW2-1 SDD Disable ADC control

3.2 RS-422 Multi-drop Network

In this topology there is only one driver sending to one or more receiv-

ers. One termination resistor is recommended at the extreme end of the

bus to eliminate reflections. Up to 10 receivers are permitted under RS-

422. Multiple receive-only nodes may be used for point-to-multipoint

communications.
