LTC 8561 | Instruction Manual | Installation
1. Prepare the ends of cables by stripping about
1⁄4-inch of insulation from the ends.
2. Connect the pan-right wire to conductor 1 on
terminal strip, J406.
3. Connect the pan-left wire to conductor 2 on
terminal strip, J406.
4. Connect the tilt-up wire to conductor 3 on
terminal strip, J406.
5. Connect the tilt-down wire to conductor 4 on
terminal strip, J406.
6. Note that not all pan/tilt heads have an auto-
pan feature or separate auto-pan wires. Refer to
your pan/tilt manual and if no auto-pan wire is
provided, omit the next step.
7. Connect the auto-pan wire to conductor 5 on
terminal strip, J406.

4.24 Auxiliary Circuits Pin Assignment

NOTE: For the LTC 8566/60 and 8566/50, the
maximum total current output, including Pan/Tilt
Output, Auxiliary 1 Output, and Auxiliary Supply
Output, is 2 A.
All receiver/driver versions have three relay
auxiliaries, each with a set of normally open and
normally closed contacts. These contacts permit the
use of line voltages or signals to be switched on and
off. An auxiliary supply output is provided to allow
operation of appliances at the pan/tilt output voltage
level. This auxiliary supply output is fused through the
pan/tilt/auxiliary supply fuse.
These circuits are controlled by executing commands
for auxiliary 2, 3, and 4. In actuality, Auxiliary 1 is
used as the auto-pan hardwire control. If software auto-
pan is in use, the installation may make use of
Auxiliary 6 to activate the auxiliary output located in
the pan/tilt connector.
Auxiliary #3 has a special mode of operation when
DIP switch S103, #2 is in the ON position. In this
mode, the auxiliary activates and latches automatically
when the IRIS control is used on the system keyboard.
This function is used to control the special ground
connection of a zoom lens which provides a manual-
iris override feature. More information is provided in
the S103, #2, Setting Option Switches section of this
manual.

Refer to the two following sections for connection
details.

4.25 Auxiliary Supply Output

NOTE: For the LTC 8566/60 and LTC 8566/50, the
maximum total current output, including Pan/Tilt
Output, Auxiliary 1 Output, and Auxiliary Supply
Output, is 2 A.
When it is desired to operate an appliance at the
pan/tilt output voltage level, the auxiliary supply
output may be used to supply power to the appliance.
Use the following steps to make use of the auxiliary
supply output. Locate terminal strip J402 AUX
SUPPLY, J405 AUX 2, J407 AUX 3, and J408 AUX 4.
Choose one of the three auxiliary terminal strips: J405,
J407, or J408.
1. Connect a jumper wire from pin 1 of J402 to
pin 2 of the selected strip.
2. Connect the appliance load to pin 1 (normally
open contact) or pin 3 (normally closed contact)
depending upon your requirements.
3. Connect the appliance return to pin 2 of J402.

4.26 Contact Auxiliary

To use an auxiliary as a circuit switch, follow these
steps:
Locate terminal strip J405 AUX 2, J407 AUX 3, and
J408 AUX 4. Choose one of the three auxiliary
terminal strips: J405, J407, or J408.
1. Use the contact as a series switch and connect
the circuit to pins 1 and 2 for a normally open
switch, or to pins 2 and 3 for a normally closed
switch.
2. If Auxiliary #3 is being used to activate the
manual-iris override mode of a zoom lens
equipped with this feature, use the normally
open contact connections. One side of the
contact should be connected to the zoom lens
special ground wire, and the other contact
should be jumpered to the lens motor common
terminal on J105.
