ACCESSORY PANELS
The following sections describes how to install the following optional,
accessory key panels:
• The XPL-12 Display Expansion Panel adds 10 talk/listen selectors to
a panel.
• The XPL-22 Display Expansion Panel adds 20 talk/listen selectors to
a panel.
The installation procedure is identical for these two panels.
XPL TYPE EXPANSION PANELS
The XPL series provides selectors labeled with electronic displays that
are automatically updated whenever changes are made.
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.
Model XPL-12 provides 10 additional selectors with displays and
model XPL-22 provides 20 additional selectors with displays. Each
panel can accept a maximum of 60 additional selectors.
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.
POWER
Each XPL panel is powered by an external AC transformer (included).
Confirm that the transformer is correct for the line voltage being used.
To connect the AC power transformer to an XPL panel, route the
transformer’s secondary lead to the “AC Power Input” connector on the
back of the panel. This is a 2.1 mm coax connector. When routing the
lead, use the lead stress relief on the back of the panel. The panel can
be powered by any 12- to 16-V RMS AC source rated for 750 mA.
PANEL CONNECTION
A cable is supplied with each panel to connect it to a panel or to
additional panels. The cable is 6-ft. long (1.8 m) and has a DB-9F
connector on one end and a DB-9M connector on the other end. If
custom length cables are to be made, they should be made with 9
conductor control cable with 22 to 24 AWG wire. The pins should be
wired one-to-one between the male and female connectors. The
maximum distance between the panel and the last expansion panel
should be 25 ft. (7.6 m).
