APPENDIX C: SYNCHRONOUS PORT
CONNECTIONS (CONFIGURED AS “DTE”)
Pin Name Description
1 FG FrameGround;connected straight to asynchronous port
2 TXD TransmitData (from2010);data output to synchronous
port
3 RXD ReceiveData (to 2010);data input from the synchronous
port;inputto 2010 power supply
4 RTS Requestto Send (from 2010);4 bit delay from
asynchronousport (2010 waits 4 bits before dropping
RTSto the synchronous port;this facilitates use in a
pollingenvironment)
5 CTS Clear to Send (to 2010);connected straightthrough to
asynchronousport
6 DSR DataSet Ready (to 2010);connected straight through to
asynchronousport
7 SG SignalGround;connected straight through to
asynchronousport
8 CD CarrierDetect (to 2010);connected straight through to
asynchronousport
9+DCV Connectedstraight through to asynchronous port
10 –DCV Connectedstraight through to asynchronous port
15 TXC Transmitclock (to 2010);used to synchronize data
conversionfrom 2010 to synchronous port
17 RXC Receive clock (to 2010);used to synchronize data
conversionfrom 2010 to synchronous port
20 DTR Data Terminal Ready (from 2010);input to 2010 power
supply
22 Rl RingIndicator (to 2010);connected straight through to
asynchronousport
