Encore Control of Horizon Serial Interface (RS-422/485)
Encore provides support for serial control of a Horizon matrix as follows:
• Matrix sizes up to 128 x 128,
• Maximum of 4 levels,
• Serial matrix (XY port) communication baud rate of 19200, and
• The Encore RS-422 SIO port baud rate is user adjustable. Supported
rates are 19200, 9600, 4800, and 2400.
The Horizon interface to the Encore control system allows users to perform
Takes from any connected point of control (including, but not limited to, an
Encore panel, a Horizon panel, and the OUI). Execution of such Takes will
result in corresponding tally on any connected point of control that is
observing an affected destination.
Cable Connections
On the back of the Horizon Control frame is a 15-pin D female connector
labeled RS-422; this is the connector to use for the interface. A 15 pin D male
to RJ-45 female adapter is required. The adapter’s 15 pin D connector end
can be plugged directly into the Horizon frame or an RS-422 male to female
cable can be used. See
Table 18 on page 38 for adaptor pinouts.
The RS-422 connector is also know as the Horizon XY port. This port was
designed as a maintenance port. Many customers have used this port to
connect XY control panels or other serial devices. In some cases, customers
have used Y cables or other splitters to connect multiple devices to the
Horizon XY port at the same time. The Encore-Horizon interface requires
Encore to be the only device connected to the Horizon using the
RS-422 (XY)
port.
