SETUP

Camera Number Assignment

For individual control of camera pan/tilt functions by a matrix
switching system, an individual camera number must be
assigned to each AD1273 unit. Two thumbwheel switches,
located on the printed circuit board, identify the camera
number for each AD1273 (see Figure 4).
NOTE: Valid identification numbers on the thumbwheel
switches are 1 - 64 only. Switches reading zero-zero
(00) and 65 - 99 are not valid numbers.
Units Digit: Set identification numbers ZERO through NINE
with the Units switch.
Tens Digit: Set identification numbers TEN through SIXTY
with the Tens switch.
EXAMPLE: Camera Identification Number is 45.
Set Units switch to five (5).
Set Tens switch to four (4).

Camera Number Sequencing

For systems containing more than 64 cameras, camera number
assignment is determined by GROUPing the cameras into
blocks and then determining a particular camera number within
that GROUP.
In this case, a GROUP contains 64 cameras (the thumbwheel
switches on the AD1273 can be set for 1-64 only). A data
distributor in the switching system routes the control signals to
the proper GROUP of cameras.
Table 2 identifies which GROUP a specific camera number
belongs to.

Setting Camera Number Thumbwheel Switches

All possible thumbwheel switch settings for the AD1273,
along with the associated GROUP numbers, are listed in the
Appendix (see pages A4 through A10 - Camera Number
Sequence Tables).
To specify the correct thumbwheel switch settings and
GROUP number;
1) Confirm the camera number.
2) Locate the GROUP for that camera (see Table 2).
3) Locate that GROUP in the Appendix (pages A4-A10)
4) Locate the camera number within the appropriate GROUP.
5) Set the thumbwheel switches to the corresponding Tens and
Units digits.
6) Set the GROUP number on the Data Distributor. Refer to
the data distributor installation manual for the GROUP
identification setting procedure.
Table 3 gives an example of the Camera Number Sequence
Tables found in the Appendix.
