After the switch is pressed, the display will instruct you to place the cal stand to the -45
degree, than to -30 degrees etc. until +60 degrees is completed. When the cal stand is placed
in the +60 degree position and the CALIBRATE switch is pressed, the program will go back to
RUN mode and the calibration procedure for that tool is finished. The accuracy of the
calibration can be checked in the RUN mode by placing the cal stand into various positions
and observing the display values. If only one tool is used, the calibration procedure is
finished. If two tools are being used, and the other tool needs calibration, repeat steps A
through D for the second tool.
COMPUTER INTERFACE
The Amphenol connector on the bottom of the box is the computer interface port.
ANZEN INTERFACE:
The connector is set up for three wire RS-422 interface, ground, +signal, and -signal. When a
Clear Vision Tool is used, the limit switch on the tool closes and dumps the angle of the tool
out of the serial port in Hexadecimal.
SERIAL PORT PROTOCOL: N, 8, 1, 4800 BAUD
DUMP STRING: (02)(x)(x)(x)(03)(xx)
02 (start of text)

BURKE E. PORTER / FORI INTERFACE:
The connector is set up for three wire RS-232 interface; ground, transmit and receive. The
interface cable plugs into the amphenol connector and on the other end of the cable is a 9 pin
"D" connector. The "D" connector plugs into any IBM or compatible computers' serial port.
When a Clear Vision Tool is used, the limit switch on the tool closes and 1.) displays the tools'
angle (on the KEI-850 box) and 2.) dumps the angle (in ASCII) out of the serial port + CR LF.
SERIAL PORT PROTOCOL: N, 8, 1, 9600 BAUD
DUMP STRING: -xx.xx CR LF
- (+/- sign of the angle)
x (tens digit)
x (ones digit)
. (decimal point)
x (tenths digit)
x (hundredths digit)
MERRILL INTERFACE:
The connector is set up for three wire RS-232 interface; ground, transmit and receive.
Connections, Protocol & Dump String are the same as Burke Porter. The only difference is
that the angle is transmitted every time the KEI-850 box receives a "Control E". ("E" is for
inquire.)
