RS-232 Control Protocol for Pêma and ‘ne’ Series Products Notes: 1) Unless otherwise noted all byte values in this document are hexadecimal, or binary equivalent to show bit assignments. All Data must be transmitted as Hex or equivalent Decimal values, (not ASCII characters). Some program environments only support ASCII or Hex data types, in which case you must use Hex. Tip: you can use MS Windows Calculator, set to Scientific (in View Menu), to convert between Binary, Hex, Decimal. NOTE: in Crestron program environment use ‘\x’ for Hex. Example: F0 is coded as \xF0 2) Hardware setup is: 1 Start Bit, 8 Data Bits, 1 Stop Bit, No Parity. Baud rate is 9600bps for all products, except the ne24.24M. The ne24.24M power-on baud rate is always 38,400bps, but it will change to 9600bps when ten $F9 bytes at 9600bps are received. 3) Message types 06, 08, and 09 (below) are only supported by the ne24.24M. 4) Message types 06 thru 1A, WR-0A, WR-0B, and WR-0C are always echoed back from the unit, to confirm reception. 5) Message types 00, 02, 04, WR-03, WR-05, and WR-07 invoke a specific response message from the unit. 6) Non-applicable or invalid messages are echoed back from the product as received. No other action is taken by the product. 7) Message type 42 is transmitted from the unit when a local preset change event occurs via contact closure, front panel buttons, etc. 8) Some DSP functions are not available in all products. Please refer to the user manual or Ashly software for available functions. All products, except for the ne24.24M, require associated DSP functions to be populated via Ashly software for each message type. Message Types: 00 = Data Request: configuration/input/output 14 = Compressor-Limiter Message 01 = Data Response: configuration/input/output 15 = Mute Message 02 = Meter Request
