LTC 8600 | LTC 8800 Series en | 53F.01U.127.393 | 2.0 | 2009.03 Instruction Manual Bosch Security Systems, Inc.• Switch 6 of S2This switch is currently not used and should be left OFF.• Switch 7 of S2This switch controls the system keyboard polling mode. When switch 7 is ON(factory default), the CPU communicates with all system keyboards via a “6 pollbyte” communication protocol. This format provides variable speed pan/tiltcontrol for AutoDome-equipped camera sites. Refer to the information forSwitch 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 communicatewith the older TC8561 Series of receiver/drivers without using the LTC 8785code converter unit. Note that the fixed speed keyboard mode allows access toonly the first 63 auxiliary and pre-position functions. This is not an issue onolder receiver/driver versions, but may pose a problem if the system must beexpected to access all functions available in the AutoDome Series of pan/tilt/zoom dome cameras or the higher preposition numbers in current versions ofAllegiant receiver/drivers.• Switch 8 of S2This switch controls the protocol settings of the external RS-232 port whichconnect to the Console, Printer, and Alarm.If the switch is turned OFF, the system uses the factory default settings for theRS-232 data communication protocols as listed below.With switch 8 ON, any RS-232 port protocols changed using the keyboard (seeUser Function 30), the optional LTC 8059/00 MCS package, or the optional LTC8850/00 GUI Software package are active.Users with Priority Level 1 can also use the keyboard (see User Function 29) toreset 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 areuser-defined programs designed to provide special system functions or featuresat system startup or reset. If the switch setting is OFF, any existing boot screenfunction 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.14.1.3 Lower CPU DIP Switch S3The lower CPU dip switch does not currently provide any user selectable options,and all settings should be left in their OFF position.Settings Console Port Printer Port Alarm Port Keyboard PortsBaud Rate 115200 115200 19,200 9600Stop Bits 1 1 1 --Data Bits 8 8 8 --Parity None None None --Handshake Yes No No --
