PRODUCT DESCRIPTION
The SCT-1034 is an Ernitec to Bosch control code translator designed to permit control of Bosch
cameras from Ernitec VIP-1500 controllers. It receives Ernitec RS-485 commands and transmits
the appropriate commands in Bosch biphase format. There are four independent biphase outputs.
The biphase output can be limited to fixed-speed-only commands for compatibility with older Burle
receivers.
Input and output connections are made with mating screw terminal connectors. Front panel LEDs
indicate status of power, receive, and transmit.
There is an optional 19" rack mount panel (one rack unit high).

SETTING THE SWITCHES
T o set the configuration switches, remove the
back panel, which is secured by two screws.
Then slide the cover back to expose the
switches. The switches can be changed while
the code translator is powered up and the new
settings will take effect immediately.

Flashes continuously while sending

The Rx indicator will flash whenever there is data from the Ernitec controller. If the input lines have
reversed polarity , the Rx indicator will be on solidly . Biphase code is repeating, so the Tx indicator
will continue to flash while the camera is moving.
If you have Rx but no Tx, possible causes are:
The Ernitec code coming into the translator is not camera control code.
The Ernitec data out is not set at 2400 baud.
If the code translator is sending data and does not get a follow-up Ernitec command in about 12
seconds, it will time out and quit sending that stream of data.

OPERATION
Pan, Tilt, Zoom, Focus, and Iris commands are converted directly.
Ernitec Store and Recall pre-position commands are converted to Bosch Set and Shot com-
mands.
Aux 1 is converted to Aux ON 1, which is interpreted by the Bosch domes as Autoscan (without
limits).
Aux 2 is converted to Aux ON 2, which is interpreted by the Bosch domes as Autopan (within
limits).
P AN & TIL T SPEEDS
If the code translator is configured for fixed speed Bosch receivers, the Pan and Tilt commands
have no speed value associated with them.
The Ernitec controller does not send speed values for Pan and Tilt commands.
If the code translator is configured for variable speed Bosch receivers, the code translator will give
a speed value to Pan and Tilt commands. On power-up, the default is a medium speed. Aux 3 and
Aux 4 are used to change the Tilt speed value. Aux 5 and Aux 6 change the Pan speed.
Each time one of those Aux buttons is pressed, a small change is made to the associated speed.
Aux 3 Decrease tilt speed
Aux 4 Increase tilt speed
Aux 5 Decrease pan speed
Aux 6 Increase pan speed
