RSS-119 148.000MHz -149.900MHz 6.25kHz, 12.5kHz, 25kHz
RSS-119 150.050MHz – 174.000MHz 6.25kHz, 12.5kHz, 25kHz
RSS-119_B1 421.000MHz – 430.000MHz 6.25kHz, 12.5kHz
RSS-119_B2 450.000MHz – 470.000MHz 6.25kHz, 12.5kHz
4 Operation
The host system communicates with the E2-455 module via the serial interface provided by either the
main or alternate host interface. The serial interface is a standard TTL UART interface in full duplex
asynchronous connection. The baud rate is 1.0Mbps. RTS and CTS lines are used to provide flow
control between the host and radio processors.
The serial protocol is a proprietary message structure.
In addition, a secondary diagnostic interface is provided over the Console interface. This provides the
interface for testing the device. It operates at a rate of 115,200 baud.
4.1 Diagnostic Interface Command Reference
4.1.1 Radio Commands – General
 Set to QAM Mode (Note: par rate command must be re-issued)
> cfg mod qam
0:15:44.891 RAD: CMX7164: Function image 4112 [ OK ]
0:15:45.603 RAD: CMX7164 Rx DC calibration [ OK ]
[1] Modulation = QAM
0:15:45.662 RAD: CMX7164 Tx DC calibration [ OK ]
 Set to FSK Mode (Note: par rate command must be re-issued)
> cfg mod fsk
0:16:35.955 RAD: CMX7164: Function image 2035 [ OK ]
0:16:36.910 RAD: CMX7164 Rx DC calibration [ OK ]
[1] Modulation = FSK
0:16:36.970 RAD: CMX7164 Tx DC calibration [ OK ]
(Note: par rate command must be re-issued after every Mode change)
 Set radio transmit modulation format
> par rate 4qam (options 4qam, 16qam, 64qam, 2fsk, 4fsk)
[1] Radio frame rate = 4QAM
 Set radio transmit FEC (only in QAM mode) to FEC or RAW
> par fec fec
[1] Radio frame FEC = FEC
> par fec raw
[1] Radio frame FEC = RAW
 Set Radio Channel Bandwidth (6.25kHz, 12.5kHz, 25kHz)
> cfg bw 12500 (Options 6250(QAM only), 12500, 25000)
0:35:03.651 RAD: CMX7164 Rx DC calibration [ OK ]
[1] Frequency bandwidth = 12500 Hz
0:35:03.694 RAD: CMX7164 Tx DC calibration [ OK ]
 Set Radio Tx and Rx Frequency (in Hz).
> cfg freq_tx 442012500
[1] Transmit frequency = 442012500 Hz
> cfg freq_rx 442006250
[1] Receive frequency = 442006250 Hz
