(3) Xmit Rate
There are two settings for the Transmit Rate parameter. For normal operation, the SRM6200E-SLC 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 Rata
The SRM6200E-SLC 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.
