RS232 Protocol
RS232 Settings:
19200, 8N1
DTR=high or low, RTS=!DTR
Note: If DTR and RTS are the same level, the RS232 transciever will not function correctly. So make sure you are able to set the one low and the other on a high level.
If no data is returned from the device, please measure the power levels of RTS and DTR on the PC's RS232 port manually. One should be +12V and the other should be -12V
Format: HHLLCC:AA
HH = ChannelID MSB
LL = ChannelID LSB
CC = ControlNumber
WHERE 08 is OK, ChannelID value can be used
EE is explicit error
AA = Activity
WHERE 0x50 or 0x51 indicated no activity
0x95 or 0x96 indicates activity
0xA7 or 0xA8 may indicate a synchronisation burst
0xFF may indicate a base channel
0x01 is an error
Note: Valid RX frequenties are: 925-960Mhz and 1805-1880Mhz
Obtaining the RX frequency from the channel ID:
ChannelID <> 0x1b00 : (ChannelID + 0x0465)*200khz
Example 1: 1EDE08:50
ChannelID = 0x1EDE
ControlNumber = 08
Activity = 0x50
RX frequency = (0x1EDE + 0x0465) * 200khz = 1805.400 Mhz
Activity == 0x50 -> No activity detected
Example 2: 170008:95
ChannelID = 0x1700
ControlNumber = 08
Activity = 0x95
RX frequency = (0x1700 - 0x0465) * 200khz = 952.600 Mhz
Activity == 0x95 -> Channel was in use during scan
