AT Commands: Telemetry and Addr List (Address List)

n=1 This parameter is used to define the length of the RTU ID in Modbus-like protocol data packets.

n=2 This parameter is used when the when the MD is set to hex 63.

MVMSK=hh

Modbus Variant ID Mask: Byte hex mask to use when extracting the ID. Specify which bits in the ID field to use. This parameter is used when the when the Mode Default (MD) is set to hex 63.

hh=hex value 00 - no mask, all 8 bits (default)

0F - only the low order 4 bits

MVOFF=n

Modbus (variable mode) Offset : Indicates the offset in the data of where the Modbus ID starts.

n= 0 - 255

MVOPT=n

Modbus Variant Option: Sets various behavioral options when dealing with a Modbus-variant protocol. This parameter is used when the when MD is set to hex 63.

n=0 : No special action (Default).

n=1 : Skip leading zeroes in Modbus packets.

Cannot be configured in Wireless Ace.

MVTYP=n

Modbus Variant Type: The data-type of the RTU ID in a modbus-variant protocol. This parameter is used to define the data-type of the RTU ID in Modbus-like protocol data packets. This parameter is used when MD is set to 63.

n=0 : Binary (Default)

n=1 : ASCII Hex

n=2 : ASCII Decimal

RKEY=n

Radio Transceiver Keying.

n=0 : Off (Default)

n=1 : On

Enable/disable MDS Radio transceiver keying. Radio keying is designed to assert CTS when a packet is received, delay the time as specified, send the data out the serial port, wait the same amount time, drop CTS. This way, the CTS signal can be used to key a transmitter on and give it time to reach its power level before data is sent to it. Delay interval is specified in S221.
