3.3 RS-485 Multi-drop Network
This topology is similar to RS-422 multi-drop. However, up to 32 receiv-
ers are permitted under RS-485. This may be used for point-to-multipoint
communications.
The converter can convert an RS-232 device into a Master node in this
multi-drop network as illustrated below:
The configuration for MASTER node is:
SW1-4 TXE Enable Driver always
SW1-6 RXC Enable Receiver RTS/ADC Control
SW1-5 RTS-D Disable RTS control
SW2-1 SDD Disable ADC control
