WFM 601 - Service Manual
Getting Started
1. Initial Equipment Connections
a. Connect an RS232 cable from the WFM 601 rear-panel RS232 connector
to the COM 1, 2, 3, or 4 connector on the PC. See the Required
Equipment List for the cable wiring illustrations.
NOTE
. Cable Wiring
If the RXD and TXD pins are swapped, as in some modem connections, the
Adjustment Procedures program will not operate.
b. Connect the WFM 601 to power and turn on the instrument.
NOTE
. Instrument Power
The WFM 601 power switch must be set to ON before the Adjustment Procedures
program is started. If the instrument is not turned on, the PC will not be able to
establish communications with the instrument. Turning the instrument power
ON after the Adjustment Procedures program is started can cause the PC to lock
up, requiring a system reset.
2. Load the Adjustment Procedures Program
a. Insert the Adjustment Procedures disk into the PC floppy drive.
NOTE
. PC Floppy Drive
On PCs the drive letter for the floppy drive may be A or B. Enter the appropri-
ate letter for your floppy drive in the following step.
b. At the PC DOS prompt, type the drive letter for the floppy drive to be
used followed by a colon, and then press the Return key.
For example,
A: <RETURN>
NOTE
. PC Hard Drive
The Adjustment Procedures program will run faster if loaded on the PC hard
drive. To load the program on the PC hard drive, create a directory on the PC
hard drive and copy the contents of the floppy disk into the directory.
c. Type CAL and then press the Return key.
