TABLE 2. RS-232 Serial Port Parameters

NULL MODEM You may need to connect the HDR 205HD’s serial port adapter to a host

computer configured as Data Communications Equipment. This is done using a

null modem. The net effect of a null modem is to reverse the Transmitted Data

and Received Data connections. Also, the Request to Send and Clear to Send

connections are reversed. This is 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.
