increasing the keyup delays for the radio equipment may help
prevent retries from taking place. If no communication failures or
retries are occurring, try decreasing both units’ keyup delays, as well
as the voice debounce time (Model 26 only) to aid efficiency. Due to
the external equipment the Model 6/26 system interfaces to,
especially in a radio environment, it generally requires analyzing and
adjustments to determine how efficient the Model 6/26 system will
be.
Problem:
CAD is not able to recognize/ or connect with the Model 26.
Solution:
Verify cable connections as listed previously. In the programming of
the Model 26, Port Configuration should be set to CAD Mode. After
CAD mode is selected, the Model 26 rear dip switches should be set
for 9600 baud and CAD mode (switches 6 UP and 7 DOWN). Refer
to the Model 26 Fire Station Dispatcher CAD Interface (027-0059)
for more information detailing Model 26/CAD protocol.
Sometimes in larger systems, communications errors can cause
unwanted delays but can be intermittent and difficult to pinpoint. The
Model 26 Data Log Mode can be used to print out the commands and
status messages going between the Model 26 and the Model 6
transponders to the PC screen. This will allow you to see which
Model 6 Station transponder is having communication issues.
To set this up, do the following:
1. Enter the Model 26 programming mode
2. Go to the Serial Port Configuration Menu and set the Model 26 to
Data Log Mode
3. Exit the programming mode on the Model 26 but leave the cable
attached and the terminal emulation program running
4. On the rear panel of the Model 26, place switch 7 in the OFF
(down) position to enable the process
At this point, all commends from the Model 26 and all responses from the
Model 6 transponders will appear on the terminal screen. An example of the
output from this arrangement can be seen in Appendix E, see page
123.
