UPC does not respond to the RS-232,
or responds with a COMMAND ERROR message.
PROBABLE CAUSES
–
Incorrect communication parameters, i.e., Serial baud rate,
parity or number of data/start/stop bits.
Handshaking signals may not be wired correctly
SUGGESTED
CURE:
Verify parameter settings match that of host computer. See
section 10.3, 10.4.
Verify handshake signals are connected properly. See
section 10.5.1 for additional help.
PROBLEM
UPC displays "TRANSITION IN PROGRESS"
for an extended length of time upon power-up.
PROBABLE CAUSES

A long Transition time was programmed into the UPC. The
UPC is designed to execute the previously executed
Program parameters or MANUAL MODE parameters upon
power-up.
SUGGESTED
CURE:
If it is desired to terminate the Transition, press the
TRANS
key. To prevent the UPC from beginning the Transition,
hold the
fn
