8.5.4.2500-40-0x Series Control Panel Rear View

8.5.4.3Typical expansion panel configuration

Since the 500-3x-3x series panels (“Standard” 8 / 16 / 24 key) only have a single expansion connection, they must form either the first or last panel in a chain. Expansion panels from the 500-40 range have both Expansion In and Expansion Out connectors, allowing them to be connected in a chain. The PathFinder configuration software includes full expansion panel support (from version 4.12 onwards). This controls the sequence in which the panels should be added to the configuration editor and the electrical interconnection sequence. Obviously, the panels may be assembled into the control desk in any preferred positions, cable lengths permitting. Two different cable types are required, Type A and Type B which are detailed in section 8.5.4.4.

The following rules need to be observed when connecting expansion panels onto a system:

¾The standard series panels have only a single expansion port, used as “EXPANSION IN” or “EXPANSION OUT”. Therefore, these panels must be connected on the beginning or end of a chain only.

¾Standard control panels (500-3x series) used in expansion mode need the internal DIP switch 1 set to “ON”. If the panels are supplied as part of a pre-configured system, this will be carried out by Trilogy and the panels marked accordingly. See Section 10.1.

¾When a standard panel appears at the end of a chain, it must be connected using cable type B (see section 8.5.4.3).

¾The audio only operates on the first panel of the chain: if required, the microphone may be removed from the second “standard” panel. Trilogy can supply a blank plug for the microphone fixing.

¾The maximum suggested cable length for interlinking cables is 10 metres.

¾A maximum of 5 panels may be configured within PathFinder. The other controlling limits are either 63 keys or 63 rotary encoders – whichever is reached first.

A number of different arrangements are shown below; others are possible.
