TC8850 Graphical User Interface software package,
or with the optional TC8x59 Master Control Software.
Switch 5
Switch 5 controls the system security modes. When
this switch is set to ON, the system log-in features
can be controlled using keyboard User Function 27
and User Function 28 (refer to section on Keyboard
User Functions for complete information). Users with
priority 1 can access User Function 27 to select if the
system keyboard log-in feature will be enabled or
disabled. When enabled, the system keyboards
require each user to 'log-on' and 'log-off' the system.
All users will be required to enter a user number and
the correct password before interaction with the
system is permitted.
Users with priority 1 can also access User Function
28 to select if the Console port log-in feature will be
enabled or disabled. When enabled, any external PC
or other computing device will be required to 'log-on'
and 'log-off' the system. Any external PC or other
computing device will be required to enter a user
number and the correct password before interaction
with the system is permitted.
If this switch is turned OFF or if the features are
disabled using User Functions 27 and 28, the system
keyboards and the Console port are always 'on-line'
with the system.
Note: When changing from the no 'log-on' to the 'log-
on' mode, all system keyboards will initially be
'logged-off'.
Switch 6
This switch is currently not used and should be left
off.
Switch 7
When switch 7 is ON (factory default), the Allegiant
CPU will communicate with system keyboards using
a ‘6 poll byte’ protocol. This format is used to provide
variable speed pan/tilt control capability for
AutoDome equipped camera sites and is only
compatible with TC8550A, TC8551A, TC8553,
TC8554, and TC8555 type keyboards. When this
switch setting is ON, DIP switch 3 (explained above)
is ignored. Note that the variable speed mode is
not
compatible with the older TC8561 receiver/drivers
without the use of a TC8785 Code Converter unit.
Switch 8
Switch 8 controls the protocol settings of the
Console, Printer and Alarm external RS-232 ports.
If the switch is turned OFF, the system will always
use 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 Keyboard User Function 30 (covered
later in this manual), the optional TC8850 Graphical
User Interface software, or the optional TC8x59
Master Control Software package 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 the
CPU’s memory. The 'boot screen' is a custom
program provided by the Factory to provide special
system functions or features. If the switch setting is
OFF, any existing boot screen will not be active.
The default (DIP switch 8 OFF or after activation of
Keyboard User Function 29) data communication
settings for the Allegiant system are listed below.
