Add — black button used to count up or add value to the screen on the DMI.
Page 4-4.
Baud Rate — speed at which data is transferred to a computer. The RAC-
200’s baud rate ranges from 300 to 19200. Page 4-14.
Cal — blue button on the DMI, it is used when calibrating the DMI or to
manually enter a new calibration number. Page 4-3.
calibration course — known distance used when calibrating the DMI. One
thousand feet is ideal, but it should not be less than 500 feet. Page 3-2.
calibration number — a number, unique to each vehicle, that represents the
pulses from the transmission received over a set distance. This number
should be as near to 0.500 - 1.200 as possible, and is necessary for the DMI
to count. Page 3-2.
CLR (Clear) — black button on the DMI that resets the distance or time
to zero. Page 4-4.
C-Hold (Count Hold) — red button on the DMI which stops the compu-
tation of distance pulses. Page 4-2.
D-Hold (Display Hold) — red button on the DMI which stops the display,
but allows the DMI to continue accumulating distance internally. Page 4-
2.
DMI — generic industry term meaning Distance Measuring Instrument.
The RAC-100 and 200 are DMIs.
DPO (Distance Pulse Output) — gray button on the DMI, when activated
it will provide a +5VDC (TTL level) output pulse at a pre-selected distance
interval and signal duration. Page 4-4, 4-5.
EEPROM — stands for Electronically Erasable Programmable Read Only
Memory. It contains the permanent memory of the DMI. Page A-3.
