B1.6.3 Serial 1/Serial 2
Touching one of these keys performs a loopback test on the relevant Serial
port. In order for the test to be successful, a 9-way D-type socket, wired as in
fi gure B1.6.3, must be fi tted to the relevant serial port at the rear of the re-
corder. If wired as shown, the socket is suitable for testing with both EIA232
and EIA485 communications standards. The test will result in the legend 'S1(2)
Passed' or 'S1(2) Failed' replacing 'Serial 1' or 'Serial 2' on the appropriate key.
If the Serial Comms option is not fi tted, pressing either key returns a 'Failed'
message.
