Description
MO
Radar mode bitmask. Bits are as follows:
Bit 0
: SI3 ASCII command compat flag. Contact us for more details.
Bit 1
: Enable console output on serial port
Bit 2: Reserved in SS300 radar
Bit 3: Reserved
Bit 4: Reserved
Bit 5: Reserved
Bit 6: Reserved
Bit 7
: Enable Rotary Switch on SS300 Break out IO board.
Bit 8
: Disable power optimized mode. RF ON all the time.
Bit 9 to 11: Reserved
Bit 12
: Detection direction. 0 = only incoming, 1 = only outgoing
SI
Speed Increment of the rotary switch on the optional break out board.
Effective low speed cutoff in radar = (LO + Rotary Switch Setting * SI)
HT
Output Hold Time in seconds. Once the output is triggered, it is held
for this amount of seconds from the last trigger source before going
inactive. Note: Only the digital output is held. The ASCII speed output
is not held. The ASCII speed output goes to 000 as soon as target is no
longer tracked.
IO
Radar IO configuration bitmask. Bits are as follows:
Bit 0: IO 1 PWM Enable for brightness control. Radars reads the
ambient light sensor connected to the IO Break out board and
adjusts load brightness via PWM. Full darkness= 5% duty cycle.
Full brightness = 100% PWM. PWM Frequency is 240Hz.
Bit 1: Set: IO 1 Active high. Clear: IO 1 active low.
Bit 2 to 7: Reserved
Bit 8: IO 2 PWM Enable for brightness control. Radars reads the
ambient light sensor connected to the IO Break out board and
adjusts load brightness via PWM. Full darkness= 5% duty cycle.
Full brightness = 100% PWM. PWM Frequency is 240Hz.
Bit 9: Set: IO 2 Active high. Clear: IO 2 active low.
Bit 10 to 15: Reserved
Note: Bit 12 of the MO variable sets direction of detection. This functionality is available
in firmware versions v115 and higher release date Jan 21
st
2010. Older radars may be
upgraded to this version. Please contact Houston Radar for a firmware update.
