DESCRIPTION
The CM9505J Junction Box and the CM9505UPS Universal Power Supply are used with
CM8500 and CM9500 matrix systems to allow the system keyboards to be placed at remote
locations throughout a facility.
The junction box can be used by itself, but in most applications is used in conjunction with the
power supply (refer to Figure 1). When used together, the junction box allows you to convert a
keyboard cable into a set of cabling that can be run significantly greater distances by eliminating
the keyboard power connections and only running the data. The CM9505UPS Universal Power
Supply reintroduces the keyboard power at the keyboard end of the cabling. For distances over
2,000 feet (609.6 m), the CM9505UPS-422 Universal Power Supply with data repeater is recom-
mended.
Communication between each keyboard and the CPU consists of two RS-422 data pairs,
+12 VDC, -12 VDC, and a ground, for a total of seven conductors. The junction boxes, power
supplies, and keyboards are supplied with 25-foot (7.6 m) pretested interconnect cables with
pre-assembled RJ-45 modular 8-pin male connectors.
