Figure 55 - RS232 Control Signals
The RTS and CTS signals control data transmission and synchronize the connected devices.
If the RTS/CTS handshaking protocol is enabled, the DS6300 activates the RTS output to
indicate a message is to be transmitted. The receiving unit activates the CTS input to enable
the transmission.
