Where a command returns a CRC byte, the CRC byte is computed based on the command value itself, plus the data returned (except as noted).

Returns the raw signal for key k, where k = {0..9} The signal value is a 16-bit number. No CRC is appended to the return.
High byte is returned first. Diagnostic use only; range is 0..4095.
Returns the reference level for key k, where k = {0..9} The reference value is a 16-bit number. No CRC is appended to the
return. High byte is returned first. Diagnostic use only; range is 0..4095.
Returns the detect integrator value for key k, where k = {0..9} The DI value is a 4-bit number, 0..0x0F. No CRC is appended
to the return. Diagnostic use only.
Returns status byte for key k, where k = {0..9} CRC byte is appended to the return. The bits in the status byte are:
Returns byte indicating which key is in detection if any, and also indicates if multiple keys are in detection, and any errors. A
CRC byte is appended to the return. If no key is in detection, bits 4 & 5 are 0. The first key number is reported in bits 0..3;
this lower nibble can have a value from 0..9. The bits in the status byte are:
Returns two bytes which indicate all keys in detection, if any. The first byte returned is the MSByte. Key 0 reports in LSByte
bit 0. A CRC byte is appended to the return.
Reports general status of the device. A CRC byte is appended to the return.
Returns CRC of EEPROM Setups only; a CRC byte is appended to the return.
Returns CRC of RAM Setups only; a CRC byte is appended to the return.
Returns two bytes which indicate all keys in error if any. The first byte returned is the MSByte. Key_0 reports in LSByte bit 0.
1 = error. A CRC byte is appended to the return.
Returns an internal code; A CRC byte is appended to the return.
Returns the 1’s complement (inversion) of the last command character received.
Sending this command two or more times will return its inverse, i.e. 0x38.
Returns the entire Setups block, followed by a CRC byte; CRC is same as RAM CRC and notably does not include the
command itself. Setups block data length is 35, + CRC makes 36.
Same as 0xC0 (Report 1st key), but no CRC is appended for faster communications
