Document #540156, Rev. IR, Model No.: VCP-011-MS-x
Protect power wires with circuit breakers or fuses located close to
the electrical power source bus.
2.4.3
The VCP is designed to interface with other AI equipment via the
RS-485 data bus. This is a bi-directional data bus that allows
multiple units to be connected simultaneously.
2.5 Physical
Requirements
2.5.1 Refer to Section 5.0 for unit dimensions and attachment points.
2.6 Electrical
Requirements
2.6.1 The VCP-011 utilizes one 15-pin connector for electrical
connections. This connector provides 28 VDC, left/right audio
output, data bus control, infrared input, and four (4) strapping pins
for alternate configuration of infrared digital command codes. Refer
to section 2.8 for connector/mating connector information.
2.6.2 The video output connector (BNC1) allows for connection of the
VCP to the video source selector. Since the video source does not
have audio switching, it will give video output only.
2.6.3 Standard configuration requires no strap pins to be connected.
Each different type of AI source equipment can be configured to
accept one of four (4) different sets of infrared codes. To change
the code settings, connect one (1) of the strap pins to the strap
common (never connect more than 1 strap pin to the strap
common). Three (3) strap pins are available to allow for up to four
(four) VCP units to be installed.
