Figure 8 - RS232 control signals
If the RTS/CTS handshaking protocol is enabled, the DS2100 activates the RTS232
output to indicate a message is to be transmitted. The receiving unit activates the
CTS232 input to enable the transmission.
RS485 Full-Duplex Interface
The RS485 full-duplex (5 wires + shield) interface is used for non-polled
communication protocols in point-to-point connections over longer distances (max
1200 m / 3940 ft) than those acceptable for RS232 communications or in electrically
noisy environments.
The connector pinout follows:
