Psion Teklogix 9160 G2 Wireless Gateway User Manual 237
Chapter 22: The 9160 G2 As Base Station
RRM Groups Configuration Settings
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 synchroniza-
tion 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
separately, 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 30.

Remote Txon

This textbox allows the user to specify the number of fill characters sent by the ter-
minal radios before the terminals send message data. The allowable values range
from 3 to 60. The default value is 13.

Active Channel

This textbox allows the user to specify the radio channel to be used by all the RRMs
in the RRM group. The allowable values range from 1 to 20. The default value is 1.
