LTC 8100, LTC 8200, LTC 8300 Series | Instruction Manual | Factory Default Settings

NOTE: This feature can also be implemented via the

PRT2CON CCL command using an external PC, dumb

terminal, or other computing device.

Communication parameters (baud & handshake) for the

Printer port can be set via Keyboard User Function 31

(covered later in this manual), with the optional

LTC 8059/00 MCS for Windows, or the LTC 8850/00

GUI software.

Switch 5 of S0202

Switch 5 controls the system security modes. When this

switch is ON (factory default), the system login features

can be controlled using Keyboard User Function 27 and

User Function 28 (see Section 13, KEYBOARD USER

FUNCTIONS). Users with priority 1 can access User

Function 27 to enable or disable the system keyboard

require each user to logon and logoff the system. All

users are required to enter a user number and the correct

password before system interaction is permitted.

Users with priority 1 can also access User Function 28 to

enable or disable the Console port login feature. When

enabled, any external PC or other computing device will

be required to logon and logoff the system, and enter a

user number and correct password. If this switch is OFF

(usually at time of system installation) or if features are

disabled via User Function 27 and 28, the system

keyboards and the Console port are always online with

the system.

Switch 6 of S0202

This switch is reserved, and should be left off.

Switch 7 of S0202

Switch 7 controls the system keyboard polling mode.

When switch 7 is ON (factory default), the CPU

communicates with system keyboards via a 6 poll byte

protocol. This format provides variable speed pan/tilt

control for AutoDome-equipped camera sites.

NOTE: The variable speed mode is not compatible with

the pre-1996 LTC 8561 Receiver/Drivers without using a

LTC 8785 Series Code Converter unit.

Dip switch 7 can be turned off (usually at system

installation) to allow operation with the older fixed

speed only type keyboards that use a 4 poll byte

protocol. In this mode, the system can communicate with

the older LTC 8561 Series of Receiver/Drivers, without

using the LTC 8785 Code Converter unit. Note that fixed

speed keyboard mode allows only the first 63 auxiliary

and pre-position functions to be accessed. 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.

Switch 8 of S0202

Switch 8 controls the Protocol Settings of the Console

and Printer external RS-232 ports.

If the switch is OFF, the system will use the Factory

Default Settings for the RS-232 data communication

protocols listed below.

With switch 8 ON, any RS-232 port protocols changed

using keyboard User Function 30 (covered later in this

manual), the optional LTC 8059 MCS, or the optional

LTC 8850/00 GUI software are active.

Users with priority level 1 can also use Keyboard 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

program previously downloaded into CPU memory. This

custom program is entered via the optional LTC 8059

MCS, or the optional LTC 8850/00 GUI software, to

provide special system functions/features. If the Switch is

OFF, any existing boot screen will not be active.

If Dip switch 8 is OFF (or after activation of keyboard

User Function 29), Data Communication Settings for

the Allegiant systems:
