COMMAND DESCRIPTIONS
Write Digital Outputs
The OEM Host issues this command to write both
digital output lines to particular states. These states will
be persistent unless overwritten by another enabled
function (such as Hop Frame).
Write PWM Output
The PWM output is a square wave with a 630.1uS
period. The PWM ratio is the ratio of the high pulse
time to the Low pulse time. A value of 0x00 will output
a continuous Low signal. A ratio of 0xFF will output a
continuous high signal. A ratio of 0x80 will put out a
repeating pulse of 315.05uS high and 315.05uS Low.
Set Max Power
The OEM Host issues this command to adjust the
maximum output power.
Max Power settings are typical and can vary by
2dBm. The maximum output power will never exceed
+21dBm for PRM110/111/120/121 or +17dBm for
PRM112/113/122/123.
EEPROM Byte Read
Upon receiving this command, a transceiver will respond
with the desired data from the EEPROM addresses
requested by the OEM Host.
EEPROM Byte Write
Upon receiving this command, a transceiver will write
the data byte to the specified address but will not echo it
back to the OEM Host until the EEPROM write cycle is
complete.
Vendor ID
This command is used to set the Vendor ID in the radios.
The Vendor ID is a one-time writable parameter which is not
able to be read back for security purposes. Radios with the
Vendor ID set will only communicate to other radios that
have Vendor ID set to the same value. Once the Vendor ID
is set it cannot be changed. Setting this value incorrectly
will result in a radio which will not be able to communicate
with other radios on the network. Setting the Vendor ID is
not necessary for the radios to operate and care should be
taken when using it. To see if the Vendor ID has been set
the OEM can issue the command <0xCC> <0xF2> <0x06>
<0xFF> <0xFF>. If the response is 0xFF 0xFF then VID has
not been set. If the response is 0x00 0x00, then the VID has
been set. Issuing the command <0xCC> <0xF2> <0x06>
<0xFF> <0xFF> will not set the Vendor ID.
