INITIAL SET-UP
For the channel concerned:
a. Connect ‘V’ re-transmission terminal to the input channel’s ‘+’ terminal
b. Connect ‘C’ re-transmission terminal to the input channel’s ‘-’ terminal
c. Connect re-transmission terminals ‘I’ and ‘V’ together using a short link or jumper.
Note... The above steps must be carried out before the calibration is started, or the calibration process will fail.
CALIBRATION
Referring to section 6.3 as necessary, access the ‘Cal Retrans’ calibration page. Select the relevant re-transmis-
sion output and operate the ENTER key.
After the calibration of the first output is complete, this process can be repeated for any further re-transmission
channels, wiring each one in turn to channel one, before operation of the ENTER key for that output.
