5.5 Connecting Bosch AutoDomes
5.5.1 Requires the Bosch LTC 8786 to convert
from RS-232 to Biphase (if used; not

5.5.2 Connect the supplied Watchdog/PTZ
control cable to the RS-232 input, on
the LTC 8786.
5.5.3 Connect the 2-conductor shielded biphase
wire from the AutoDomes to the biphase
output on the LTC 8786. The connections
are polarity-sensitive; (+) positive, (-)
negative, (S) shield. Use 18 - 2 twisted
shielded Belden 8760 or equivalent.
5.5.4 The LTC 8786 is recommended for use in
most cases, and supports 16 biphase outputs.
