Raven X EV-DO for Verizon - User Guide, version 2.34 88
AT Commands: Telemetry and Addr List (Address List)
MVMSK=hh
MVOFF=n
MVOPT=n
MVTYP=n
RKEY=n
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.
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
Modbus (variable mode) Offset : Indicates the offset in the data of where the Modbus ID
starts.
n= 0 - 255
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.
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
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.
