8.12 Troubleshooting the Interface
250
If the interface is not working properly, check the following causes and solve the
problem accordingly. In particular, if you are using a PC from the NEC PC-9801
series as the controller, refer to the following because there are some precau-
tionary notes specific to that series.
* Causes and solutions without a mark are common to both RS-232C and GP-IB.
8.12 Troubleshooting the Interface
Symptom Cause/Solution
RS-232C/GP-IB does not work at
all. • Is the cable connected properly?
• Is the power of all connected devices turned on?
• Is the correct cable being used?
• Are the settings of the communication conditions correct?
• Is the address setting of the unit correct?
• Is the address identical to that of another device?
Cannot perform RS-232C/GP-IB
communication properly. • Are the RS-232C settings (baud rate, data bit length, parity, and stop
bits) of the Models 3504-40, 3504-50, 3504-60 unit and PC the
same?
• Configure the message terminator (delimiter) of the controller prop-
erly.
See
"Message Terminator" (p. 143)
The keys do not work after using
RS-232C/GP-IB for communica-
tion.
• Press the
LOCAL
key on the panel of the unit to cancel the remote
state.
• Was the LLO (local lockout) command sent?
• Send the GTL command to switch to the local state.
The program stops when attempt-
ing to read data in INPUT. • Be sure to send a query each time before INPUT.
• Did the sent query generate an error?
The GP-IB path is stopped when
attempting to read data in INPUT
@ (ENTER). • Be sure to send a query each time before INPUT @ (ENTER).
• Did the sent query generate an error?
An operation is not performed
even though the command was
sent.
• Use
*
ESR?
to view the content of the standard event status register
and confirm the type of error.
• Use
* ERR?
to check whether an RS-232C communication error was
generated.
The number of read data sections
was insufficient (PC-9801). • Try using LINE INPUT for data including a comma (,).
Only one response was returned
despite sending multiple queries. • Was an error generated?
• Perform one read for each query sent. When you want them to be
read in one go, use message separators and place the description on
a single line.
The query response message dif-
fers from the indications on the
panel. • The indications when the controller performs the read may some-
times not match because the response message is created when the
unit receives the query.
