DSR

SG

CD

Frame Ground; connected straight to asynchronous port

Transmit Data (from 2010); data output to synchronous port

Receive Data (to 2010); data input from the synchronous port; input to 2010 power supply

Request to Send (from 2010); 4 bit delay from asynchronous port (2010 waits 4 bits before dropping

RTS to the synchronous port; this facilitates use in a polling environment)

Clear to Send (to 2010); connected straight through to asynchronous port

Data Set Ready (to 2010); connected straight through to asynchronous port

Signal Ground; connected straight through to asynchronous port

Carrier Detect (to 2010); connected straight through to asynchronous port

+DCV Connected straight through to asynchronous port

–DCV Connected straight through to asynchronous port

TXC

RXC

DTR

Transmit clock (to 2010); used to synchronize data conversion from 2010 to synchronous port

Receive clock (to 2010); used to synchronize data conversion from 2010 to synchronous port

Data Terminal Ready (from 2010); input to 2010 power supply

Rl Ring Indicator (to 2010); connected straight through to asynchronous port
