Figure 2.14 - RS232 control signals

The RTS232 and CTS232 signals control data transmission and synchronize

the connected devices.

If the RTS/CTS handshaking protocol is enabled, the DS4300 activates the

RTS232 output to indicate a message is to be transmitted. The receiving unit

activates the CTS232 input to enable the transmission.
