Chapter 22: The 9160 G2 As Base Station
RRM Groups Configuration Settings
Callsign String
This textbox allows the user to specify the text to be transmitted as the RRM's callsign. The
text is transmitted as Morse code. The default value is Teklogix.
22.4.2.3 Radio Parameters
Because some of the radio parameters are identical for a given group of timeplexed RRMs,
they may be configured by the user once on the 9160 G2; the 9160 G2 then passes them to
the RRMs in the group. These parameters include the synchronization delay (Sync Delay),
the remote transmit on-time (Remote Txon), and the channel number to be used (Active
Channel).
Although the RA1001A narrow band radio in each RRM in the group is configured sepa-
rately, the 9160 G2 assumes they will be configured identically. To ensure this, the 9160 G2
looks at certain parameters returned by each of the RRMs. These parameters include the
radio baud rate and the transmit-on time.
These parameters are compared against the values returned by other RRMs within the same
group. Error messages are displayed should these values not match, but the worst case value
is chosen for use.
Warning: These parameters are pre-configured for your system, and should not be
changed without a proper understanding of how they affect the radio link.
Sync Delay
This textbox allows the user to specify the number of delay characters inserted between the
RRM's transmission and the first response window. The allowable values range from 3 to
45. The default value is 22.
Remote Txon
This textbox allows the user to specify the number of fill characters sent by the mobile com-
puter radios before the mobile computers send message data. The allowable values range
from 3 to 60. The default value is 13.
