Teklogix 9150 Wireless Gateway User Manual
Message Mode Limit
This textbox allows the user to specify the probability of including a message-mode
poll in its poll transmission. The allowable values range from 3 to 7. The default
value is 4.
Callsign Period
This textbox allows the user to specify the amount of time between transmissions of
the callsign. This parameter is in minutes. A value of 0 (zero) indicates that no call-
sign is transmitted. The allowable values range from 0 to 60. The default value is 0.
Callsign String
This textbox allows the user to specify the text to be transmitted as the RRM’s call-
sign. The text is transmitted as Morse code. The default value is Teklogix.
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 9150; the 9150 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 TRX7370 narrow band radio in each RRM in the group is configured
separately, the 9150 assumes they will be configured identically. To ensure this, the
9150 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 28.
