Radio Frequencies and Modulation Format
As noted in Section 4.3.4 above, the MRC-565 will already be programmed with the authorized
frequencies to be used in your network. These frequencies are stored in parameter memory and
cannot be changed. Verify that the correct frequency is configured by entering the command:
CHANNEL (cr)
The following table will be displayed for a LOS network:
+CHANNEL 01/01/00 01:08:29
Primary Channel TX mhz RX mhz Mod-Val Bit rate Modulation
00 40.0000 40.0000 3 9.6K gmsk9.6
Channel Table:

You can select any frequency pair from the frequency table by entering the following commands:
ASSIGN,RX1,n Where n is the channel number you want to assign to RX1.
CHANNEL, n Where n is the desired channel number
5.2.2 Device Type
The MRC-565 can operate as either a Remote Station, or Base Station. Use the DEVICE
command to select the mode you require.
For normal MRC-565 Remote Station operation, enter:
DEVICE,REMOTE
As a Remote Station, the device will connect to a Base Station using base station selection
algorithm.
For MRC-565 operation as a Base Station, enter:
DEVICE,BASE
BASE operation is used exclusively in ELOS networks. BASE stations are usually connected to
a back office host computer through a wired network connection (Ethernet)
