-34-
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.
