LTC 8561 | Instruction Manual | Summary of PIN Assignments

6.2 Home Position

The home position feature calls up pre-position
number 1 after there has been no PTZ commands
received by the receiver/driver for approximately two
minutes. This feature is enabled by turning AUX-9
ON or disabled by turning AUX-9 OFF.

6.3 Tour

The Tour function sequences the unit through all set
pre-positions and is controlled from the system
keyboard by using the auxiliary 8 command. Auxiliary
8 ON activates the function, while Auxiliary 8 OFF
deactivates it.
The time interval between the tour steps can be
programmed from approximately 10 seconds to 128
seconds. Use AUX-15 ON to increase the time and
AUX-15 OFF to decrease the time. The time can be
incremented repeatedly by pressing the ENTER key.
The time increments are in approximately 4 second
intervals.
Individual pre-positions can be enabled/disabled from
the Tour.
SET 9XX: Disable pre-position xx
SHOT 9XX: Enable pre-position xx
SET 900: Disable all pre-positions from Tour.
SHOT 900: Enable all pre-positions from Tour.
SET 899: Disable all pre-positions from Tour.

Where xx equals pre-position numbers 1-99.

6.4 Camera Command Pass-through

This receiver/driver allows biphase commands to be
Passed-through to the camera via the RS-232 TX port,
allowing Aux commands to be entered at the keyboard
to alter certain camera parameters. The LTC 0600 or
the LTC 0500 Series cameras need to be addressed to
1 minus the address of the receiver/driver, then
physically wired from the RS-232 port of the camera
to the RS-232 TX port of the receiver/driver. For
example, if the receiver/driver is set to address 02, the
camera needs to be addressed as 01. This camera
secondary addressing is accomplished via PC software
(LTC 0650).
