Connecting the DGy 201x’s serial port to a computer configured as Data Communications Equipment (DCE) is done using a null modem. The net effect of a null modem is to reverse the Transmitted Data and Received Data connections within the cable. Also, the Request to Send (RTS) and Clear to Send (CTS) connections are reversed. This may be done by using a special null modem cable, or by inserting a small null modem box or cable in series with a regular straight through cable.
