9 .2 .1 AGC Mode (Hand-held Display)
Operating in the AGC mode provides for plug-and-play RF level setting as the transmitter automatically sets the internal
attenuators for the optimal laser drive level and OMI. When in the AGC mode the variable attenuators will automatically
be adjusted for each laser transmitter so the RF reference display will read 0.0 dB ± 0.5 dB. The following provides the
procedures and associated menus for configuring the DMTx4 with the Hand-held Display in the AGC mode.
1. Connect power to the chassis. Unit should power up (no switches).
2. Plug the RS-232 cable from the Hand-held Display into the RS-232 port on the CF-CTLR control and communications
module.
3. Using the Hand-held Display choose the appropriate slot for the desired module location.
4. Example DMT34 - With a combined Broadcast/Narrowcast total RF power of 31 dBmV plug the Broadcast cable into
