Bosch Appliances LTC 8800, LTC 8600 instruction manual Lower CPU DIP Switch S3

LTC 8600 LTC 8800 Series en 53

•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.

NOTE 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.

Settings	Console Port	Printer Port	Alarm Port	Keyboard Ports
Baud Rate	115200	115200	19,200	9600
Stop Bits	1	1	1	--
Data Bits	8	8	8	--
Parity	None	None	None	--
Handshake	Yes	No	No	--

14.1.3 Lower CPU DIP Switch S3

The lower CPU dip switch does not currently provide any user selectable options, and all settings should be left in their OFF position.
