N U L L M O D E M 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.
