Switch 7 of S2
This switch controls the system keyboard polling mode. When switch 7 is
ON
(factory default), the CPU communicates with all system keyboards via a “6 poll
byte” communication protocol. This format provides variable speed pan/tilt
control for AutoDome-equipped camera sites. Refer to the information for
Switch 3, above, for more details.

NOTE
The variable speed mode is not compatible with the pre-1996 TC8561 receiver/driv-

Dip switch 7 can be turned
OFF (usually at system installation) to allow opera-
tion with the older fixed speed-only type keyboards that are able to communi-
cate only using the older format. In this mode, the system can communicate
with the older TC8561 Series of receiver/drivers without using the LTC 8785
code converter unit. Note that the fixed speed keyboard mode allows access to
only the first 63 auxiliary and pre-position functions. This is not an issue on
older receiver/driver versions, but may pose a problem if the system must be
expected to access all functions available in the AutoDome Series of pan/tilt/
zoom dome cameras or the higher preposition numbers in current versions of
Allegiant receiver/drivers.
