Lower Cpu Dip Switch S3 - Bosch LTC 8600 Instruction Manual

LTC 8600 | LTC 8800 Series
NOTE

14.1.3 Lower CPU DIP Switch S3

F.01U.127.393 | 2.0 | 2009.03
• Switch 6 of S2
This switch is currently not used and should be left OFF.
• 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.
The variable speed mode is not compatible with the pre-1996 TC8561 receiver/driv-
ers without using an LTC 8785 Series code converter unit.
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.
• Switch 8 of S2
This switch controls the protocol settings of the external RS-232 port which
connect to the Console, Printer, and Alarm.
If the switch is turned OFF, the system uses the factory default settings for the
RS-232 data communication protocols as listed below.
With switch 8 ON, any RS-232 port protocols changed using the keyboard (see
User Function 30), the optional LTC 8059/00 MCS package, or the optional LTC
8850/00 GUI Software package are active.
Users with Priority Level 1 can also use the keyboard (see User Function 29) to
reset any changed protocols back to the default settings (see below).
Switch 8 also controls the activation of a "boot screen" Command Script pro-
gram previously downloaded into the CPU's memory. Command Scripts are
user-defined programs designed to provide special system functions or features
at system startup or reset. If the switch setting is OFF, any existing boot screen
function will not be activated.
The default (DIP switch 8 OFF or after activation of Keyboard User Function 29)
data communication settings for the Allegiant system are listed below.
