CONNECTIONS AD1684B
Pre-position (Preset) Connections
The Receiver connection to a Pan/Tilt or Lens unit with pre-
position servos is with a ten (10) pin connector labeled J4 (see
Figure 1, page 2). For dual-channel operation a second 10-pin
connector labeled J3 is used for channel B. Table 7, page 11,
lists the pin designations from the Receiver to the Pan/Tilt and
Lens servos and provides space for the installer to record the
pinouts for the specific installation.
Mating 10-pin screw-terminal connectors are provided for each
PCB connector (see Figure 5, page 7). The connector
terminals accept wire gauge sizes from 22-AWG to 14-AWG,
stripped 1/4" (6mm) from the end.
BEFORE STARTING:
1. Check power line to verify that power is off.
2. Open the Receiver and locate the Pre-position connector J4,
located on the left side of the PCB. For two-channel
operation, also locate connector J3.
WIRING INSTRUCTIONS:
3. Pass the wire through the bushing to the Pre-position
connector, do not tighten bushing.
4. Strip the ends of Pan/Tilt and Lens servo wires.
5. Insert the PAN (WIPER) wire of the Pan/Tilt servo into the
mating screw-terminal connector pin location for PAN.
6. Insert the TILT (WIPER) wire of the Pan/Tilt servo into the
pin location for TILT.
7. Insert the FOCUS (WIPER) wire of the Lens servo into the
pin location for FOCUS.
8. Insert the ZOOM (WIPER) wire of the Lens servo into the
pin location for ZOOM.
9. Insert the SERVO (+) wire of the Pan/Tilt servo into the pin
location for + REF.
10. Insert the SERVO (-) wire of the Pan/Tilt servo into the
pin location for - REF.
11. Insert the SHIELD of the Pan/Tilt cable into the pin
location for SHIELD.
12. Insert the SHIELD of the Lens cable into the pin location
for SHIELD.
13. Remove any excess cable and tighten the bushing.
14. Insert the screw-terminal connector into the J7 connector.
For dual-channel operation, repeat steps 3 through 13 for
Channel B, using connector J3 on the PCB.
Note: (+) REF and (-) REF are voltage direction indicators.
The definition of direction can be different among
manufacturers. Reversed connections will cause the
Pan/Tilt or the Lens to move in the opposite direction until
it hits the stops. Reversing the (+) REF and the (-) REF
on the effected unit will correct the problem.
Pre-position definitions
PAN:
When the pan pot wiper is negative in reference to the pre-
position stored in a Receiver, a "Call Shot" to that pre-
position pans to the left (wiper pot becomes more
positive). When the pot wiper is positive in reference to
the pre-position stored in a Receiver, a "Call Shot" pans to
the right (wiper becomes more negative).
TILT:
When the tilt pot wiper is negative in reference to the pre-
position stored in a Receiver, a "Call Shot" to that pre-
position tilts down (wiper pot becomes more positive).
When the pot wiper is positive in reference to the pre-
position stored in a Receiver, a "Call Shot" tilts up (wiper
pot becomes more negative).
FOCUS:
When the focus pot wiper is negative in reference to the
pre-position stored in a Receiver, a "Call Shot" to that pre-
position focuses near (wiper pot becomes more positive).
When the pot wiper is positive in reference to the pre-
position stored in a Receiver, a "Call Shot" focuses far
(wiper pot becomes more negative).
ZOOM:
When the zoom pot wiper is negative in reference to the
pre-position stored in a Receiver, a "Call Shot" to that pre-
position zooms telephoto (wiper pot becomes more
positive). When the pot wiper is positive in reference to
the pre-position stored in a Receiver, a "Call Shot" zooms
wide (wiper pot becomes more negative).
Refer to the Typical System Connections, page C-4, for
illustration of Pan/Tilt Preset connections.
