DS4600A

The RTS232 and CTS232 signals control data transmission and synchronize the

connected devices.

Figure 9 - RS232 Control Signals

If the RTS/CTS handshaking protocol is enabled, the DS4600A 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 following pins of the 25-pin connector are used for RS485 full-duplex

communications:

Pin Name Function

2 TX485+ RS485 transmitted data +

4 TX485- RS485 transmitted data -

3 RX485+ RS485 received data +
