There are 32 hopping patterns available (0-31). It is zero by default

(P) TX POWER MENU

The Tx Power allows the ‘transmit’ power to be changed. Figure 6-6 below shows what output power

levels are available. System engineers should use the minimum amount of power consistent with

maintaining a solid data link. This will minimize the amount of interference between units and other

equipment. Also the total output from the Antenna should not be more than 1 watt E.I.R.P (30dBm)

noting that your antenna may provide gain and your cables and connectors produce a loss.

(R) RSSI trigger level – This value can be set between -120dBm and -50dBm. The RSSI trigger

level is only used by a slave modem when the unit first looks to lock onto the operating network.

Different values are used to enable the slave to better reject noise when first acquiring network link.

The factory setting is optimal for most circumstances. Increase RSSI in situations where the signal

strength of noise is unusually high.

To change the RSSI trigger level, press (R). The following will be displayed:

Enter RSSI trigger value as dBm (-120 to -60): -110

The value can be between –120 to –60 dBm. It is -110dbm by default
