Thecodetranslator is designedtoconvert Philips RS-232cameracontrolcode toPelcoRS-422code
for a single P/T/Z. Only camera commands for the address matching theAddress Selector switches
willbeconverted.

between the translator and the P/T/Z can be checked without a Philips controller.

Pelco Code Type
Both "P" code and "D" code are supported.
Baud Rates
If "P" code is selected, the output can be either 4800 baud or 9600 baud.
If "D" code is selected, the output is fixed at 2400 baud.
Parity
If "P" code is selected, the output can be set for either no parity or even parity.
If "D" code is selected, switch 3 is ignored and the ouptut is fixed at no parity.
Autospeed
When receiving fixed speed Philips pan and tilt commands, the code translator assigns a speed
value to the Pelco output code. If switch 4 is Off, this is a medium speed. If switch 4 is On, it starts
with a slow speed and then gradually increases speed.
Addressing
Only camera control code for the camera number set by theAddress Switches is converted.
If switch 5 is On, the Pelco output code will always be sent to camera #1
Test Pattern
When switch 6 is on, the translator sends a continuous small square movement pattern to the
camera. The input is not active while the test pattern is On.
Indicators
TheRx LEDwillflashwhen valid Philips data is received.
The Tx LED flashes for each Pelco packet sent.
OPERATION
Operation of the code translator is transparent to the user. Philips pan, tilt, zoom, focus, iris, pre-
positionandauxcommands1~8 are converted to the equivalentPelcocommands.Higherauxcom-
mands are used to send Pelco extended commands according to the following table
