POWERING UP
After making all connections to the 2091, (DATA Lines and
Control Code lines) and setting the camera blocks whose pan/tilts
are to be controlled, plug in the unit.
If valid dataline is being received the green LED for the
Dataline(s) (Code 1 or Code 2) will light and glow steadily. If
the light flickers there may be a problem with the code line.
RECEIVERS
Various models of 1680 and 1640 Series Receivers are available
for control of pan/tilt; lens zoom, iris and focus; and auxiliaries at
suitably-equipped camera sites. See 1640 and 1680 series data
sheets available from your dealer to determine which model will
suit your needs. For older model 1680 Receivers, the control
words may need filtering, as described in Filter Selection, page 4.
Receivers are controlled by Control Code signals received from
the code generator/distributor via code lines or other simplex
communication links such as phone, laser, microwave, radio, etc.
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. 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 five Control Code 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 CHAINED” configurations.
