Control Register #66 (0x42) (control_reg[66]:)
Notes
Preamp DC control:​ Range 0­255
●
● Used in DC compensation servo loop
Control Register #67 (0x43) (control_reg[67]:)
Bit Description
Not Used
Bits 4­7
Bits 0­3 Signal power level control 0x0­0xf
Notes
Transmit power control: ​ L aser drive control bits (7 through 4) ref, bits (3 through 0) signal.
●
● Maximum value set at factory 3amps. The maximum output power of the optical source is set
through a factory selected resistor which limits available current to the transmit source.
● When using laser devices, which have a much higher operating current, do not increase the
reference control level beyond the factory settings.
● Increasing the reference control level may cause premature failure of the internal reference diode.
Control Register #68 (0x44) (control_reg[68]:)
Notes
● Processing range gate (low byte):​ Sets the starting location for range processing in the
correlation
Control Register #69 (0x45) (control_reg[69]:)
Notes
Processing range gate (high byte)
●
Control Register #70(0x46) (control_reg [70]:)
Notes
Single bit passed from microcontroller PWM output:​ High at mode pin returns pulse width
●
proportional distance
Control Register #71 (0x47) ­ Mode/Status (control_reg[71]:)
