5.3.2 Addressing
The address is set on the CPU board PCB8500110. The switch is labeled SW1.
Setting the switch in the “ON” position represents a zero. The first five positions set
the receiver address (1 through 5) from a range of 0 to 31. The last three (6 through 8)
set the baud rate. Refer to Table B.
SW1.1 — Address Bit 0
SW1.2 — Address Bit 1
SW1.3 — Address Bit 2
SW1.4 — Address Bit 3
SW1.5 — Address Bit 4
SW1.6 — 9600 Baud
SW1.7 — 4800 Baud
SW1.8 — 2400 Baud
5.3.3 Receiver Cards
The RS-422 style Intercept
®
receivers use only two of the three receiver cards.
There must be a power supply (either AC or DC) and a CPU card. The video card is
not used. Therefore the camera video output is connected directly to the slip ring.
This eliminates the dome’s ability to superimpose text on the video. This eliminates
any label and zone feature. If these features are needed additional firmware will be
needed.

Commands are divided into two (2) categories. The first is referred to as PTZ com-
mands. The second category is Extended commands. The paragraphs below de-
