8 . Module Connections
The following describes the initial RF and optical connections to the chassis and module.
8 .1 RF Connections
RF connections are made at the back of the ChromaFlex chassis. The DMT24 and DMT34 have one broadcast input
which is shared across each laser transmitter and two or three narrowcast inputs for the dedicated services to each laser
transmitter. The DMT44 has a single RF input for each laser transmitter where the common broadcast and each individual
laser transmitter narrowcast channels is externally combined prior to connection to the chassis.
NOTE: Each laser transmitter should have the same common RF channel content below 270 MHz.
The following table and diagrams show the corresponding RF connector to module slots for the DMTx4 transmitter modules.
The RF connector numbering corresponds to the chassis slot number – laser transmitter number. For example, RF
connector 1-1 is connected to chassis slot 1- laser transmitter 1 within the module. RF connector 1-2 is connected to chassis
slot 1- laser transmitter 2 within the module.
