Connection to the PCK is as follows:
•
Connect either the RS422 / RS485 to the video control equipment.
•
Connect either a transformer or a suitable DC power source.
•
Optionally plug in a standard PC type joystick.
3. OPERATION
On power up the unit will display it’s address, an introductory message, a message showing which mode of operation
has been set up and the current software revision number. The PCK will automatically test for the presence of a
joystick. If a joystick is connected to the PCK, the unit will automatically calibrate the centre position of the joystick.
It is therefore important that the joystick is left at it’s centre position while the PCK is powering up.
3.1. Numeric Selection Keys
In order to make a selection using the numeric selection keys, type in the required number using the keys “1” to “9” and
“0”. When the required value has been typed in, press the “Enter” key. The function of the “Enter” key varies
depending on the current operating mode of the system.
Errors in entering values may be corrected either with the backspace key “<-” or with the “Clear” key.
