cc range: 0 - 3 (default = 0) RXSTART {lo_freq} {highside} {attn} Enables the receiver in continuous reception at a designated frequency (lo_freq) with a choice of low or high side modulation (highside) and with designated attenuation setting (attn). highside range: 0 or 1 (default = false = 0) attn: range: 0 - 15 DEEPSLEEP Puts the module into deep-sleep after a delay of half a second until woken by a reset or activity on UART. PCMLB {pcm_mode} Sets the PCM to loop back mode, where the data read from PCM input is output again on the PCM output. If pcm_mode = 0, module is slave in normal 4-wire configuration If pcm_mode = 1, module is master in normal 4-wire configuration If pcm_mode = 2, module is master in Manchester encoded 2-wire configuration PCMEXTLB {pcm_mode} Sets the PCM to external loop back mode, whereby the data written to PCM output is read again on the input. Check is made that the data read back is the same as that written. The external loop back may be a simple wire. Modes are save as above. LOOPBACK {lo_freq} {level} Receives data on set frequency lo_freq for data packets and then retransmits this data on the same channel at output power level. CFGXTALFTRIM {xtal_ftrim} This command can be used to set the crystal frequency trim value directly from iWRAP. This is not a permanent setting! xtal_ftrim range: 0 - 63 PCMTONE {freq} {ampl} {dc} 78
