6 RS LINK FUNCTION
6.3 Troubleshooting
If communication with the personal computer is not functioning
well, refer to the following examples:
•
If no response to the entered command is received from the
EV Counter.
1) Is the RS LINK cable connected properly?
2) Is a straight-type RS-232C cable used?
3) Are the personal computer and EV Counter communica-
tion conditions consistent?
4) With some computers it is necessary to specify the com-
munication port and whether it is to be used. Is a cable
properly connected to the specified port?
5) Is key operation or parameter setup operation being per-
formed?
(During the above-mentioned operations, RS-232C com-
munication function is paused/suspended.)
•
The initial setup operation cannot be terminated ("-----"
flashes on the D-EV).
•
Some counter enter the counting stand-by state ("-----" is
displayed on the D-EV) while the power is being turned on.
1) Is the RS LINK cable connected properly?
2) If EF Counters are being used with EV Counters, make
sure that the Digimatic selection parameter of the EF
Counter is set to "RS LINK".
After removing the cause of the error, reset the power
to all counters.
•
A command (such as a zero-set or preset command) from
the personal computer can be executed, but no data can be
acquired. Or, data processing is stopped during data acquisi-
tion.
1) Is the response output from the counter read with such as
the zero-set command, etc?
2) Is the next command issued before the response output
from the counter is received?
3) Is the number of channels connected via the RS LINK
function consistent with the number of data pieces to be
acquired?
•
A command abnomaly occurs if a command is issued.
1) Was a command consisting of 2-byte characters or lower-
case characters issued?
2) Don't you specify a number greater than the number of
channels connected?
