CONNECTIONS
Data Line Connections (1995 or 1996)
A DATA LINE is connected from the DATA LINE OUT
BNC on a Matrix Bay to the DATA LINE IN BNC on the
rear panel of the Auxiliary/Alarm Follower. (Older 1995
systems used the term LAN IN/OUT). Use a good grade RG-
59 video cable (Belden 8241 or equivalent). The DATA
LINE OUT BNC on the Auxiliary/Alarm Follower must be
fitted with a 75-ohm BNC terminator, or if used to loop to
other DATA LINE controlled equipment, it must be
terminated at the end of the run.
The LED labeled DATA LINE on the 2033 will illuminate
when a valid code is received on the Data line.
Control Code Line Connections (1650A or 2150)
The terminal connector located at the lower left side of the
2033 is used for Control Code connections. The connector is
labeled B, W, and S. The B is for the BLACK code wire, the
W is for the WHITE code wire, and the S is for the SHIELD
wire.
The Control Line connections to the Auxiliary Follower must
be shielded, 2-wire twisted pair (Belden 8760, for Plenum,
use Belden 88760 or equivalent).
If the Auxiliary/Alarm Follower is used with Control Code,
remove the top cover of the unit and locate the DIP switch on
the printed circuit board. Turn the eighth switch ON. This
enables the use of the Control Code.

Control Code lines must be terminated in 120 ohms. Check
the last unit on each line to ensure that 120-ohm termination
is present. Intermediate units on a Control code line must not
have 120-ohm termination. To remove the termination of the
2033 code line, jumper J32 must be removed from the main
PCB.
In seitching systms using Control Code, the Auxiliary
Follower must be connected to code line that contains the
cameras and monitor to be followed.
For 1650A operation, there can be a maximum of four control
lines. The first control line is for monitors 1-8 and cameras 1-
64. The second control line is fo monitors 1-8 and cameras
65-128. The third control line is for monitors 9-16 and
cameras 1-64. The fourth control line is for monitors 9-16 and
cameras 65-128.
For 2150 Systems, one control line is available for a
maximum of 32 cameras and five monitors.
Code Lines are NEC Class 2, low voltage circuits. Where
local codes permit, installation conduit is not required. Avoid
installation near high voltage sources or other potential
interference sources. Control Code lines must be terminated
in 120 ohms. Check the final code-controlled unit on each
code line and, if a 120 ohm termination is not present, add
one.
Up to three Control devices may be "daisy-chained" on a
single code line. When devices are daisy-chained,
intermediate devices must not terminate the control line. Be
sure to check that the intermediate equipment does not
contain a 120 ohm terminating resistor. If it does, remove it.
See Figures 3 and 4 for "STAR" and "DAISY-CHAIN"
configurations.
