(3) Xmit Rate
There are two settings for the Transmit Rate parameter. For normal operation, the WLM should be set at
Transmit Rate 1. Transmit Rate 0 is useful to qualitatively gauge signal strength. When set to Transmit Rate 0
the radio modems will transmit data back and forth continuously, and the strength of the signal may be gauged
by viewing the Show Radio Statistics option.
Due to the fact that the radio modems transmit continuously when Transmit Rate is set to 0 (whether or not they
have data to send) they use radio frequency spectrum unnecessarily. Therefore, Transmit Rate 0 should be used
only as a diagnostic tool and not for normal operation.
(4) RF Data Rate
The WLM has two settings for the RF Data Rate (the speed that the modems talk to each other). Setting 2
should be used when the radio modems are close together and data throughput is to be optimized. Setting 3
should be used when the radio modems are farther away and a solid data link is preferred over data throughput.
Note:
The RF Data Rate setting must be identical for all units in the system. Any radio modem with a
different RF Data Rate than the master will not establish a communication link.
(5) RF Xmit Power
The WLM offers users the ability to modify the Transmission Power of the radio modem. There are 10
power settings available (1-10) which are roughly linear. Therefore a setting of 10 is full power (or 500 mW) and 1
is 10% power (or 50 mW). The following guidelines should be followed when setting the RF Transmission Power:
