Note:  Expansion panel types (lever key, pushbutton or rotary) may not be mixed in a 

daisy chain of such panels and must be connected to a main panel of the same 

type. 

Note:  The V16LDE expansion panel can only be used with the V32LD panel.  

Only one rack unit (1RU) of a standard Electronics Industry Association 

equipment rack is required for each expansion panel. The panels’ compact size 

makes them ideal for use in TV control rooms, edit suites, mobile OB vans, and 

any other location where many talk/listen keys are necessary but space it at a 

premium.  

All panels provide 12 or 16 additional selectors with displays. 

4.1.3.1 

Mounting 

All accessory panels are mounted in a standard 19-inch wide (48.3 cm) 

standard Electronics Industry Association rack, requiring one unit of rack space 

each. Leave at least 2 in. (51 mm) of clearance behind the rear of the chassis 

to allow for cable connectors. 

4.1.3.2 

Power 

Each expansion panel is powered by an external power supply which may be 

mounted on the back of the panel using the mounting clip provided. To connect 

the power supply to an expansion panel, route the transformer’s output lead to 

the power connector on the back of the panel. This is a 4 pin connector.  

4.1.3.3 

Panel connection 

A cable is supplied with each panel to connect it to a main panel or to 

additional expansion panels. The cable is a 6-ft. long (1.8 m) CAT5 cable with 

RJ45 connectors at each end. If custom length cables are to be made, they 

should be made with cable with 22 to 24 AWG wire. The pins should be wired 

one-to-one between the RJ45 connectors. The maximum distance between the 

panel and the last expansion panel should be 25 ft. (7.6 m).  

To connect an expansion panel to a main panel: 

1)  Plug one end of the CAT5 cable into the RJ45 expansion socket on the 

back of the main panel. 

2)  Plug the other end of the CAT5 cable into the input connector on the 

back of the expansion panel. 

To connect an additional accessory panel: 

1)  Plug the CAT5 cable into the output connector of the last expansion 

panel in the chain.  

2)  Plug the other end of the CAT5 cable into the input connector of the 

new expansion panel. More panels can be added by using this daisy-

chaining method. 

The numbering of expansion selectors follows the order of the daisy chaining.
