Order of Commands in a Program
Message
Normally, the programming commands in a program-
ming message can be placed in any order.
However, the following commands must always be
placed at the end of a program message since any com-
mand sent after them will disable the selection:
INPA? MEAC?
BUS? ID?
These commands will be ignored if found anywhere but
in the end of a message.
<number>
In some program commands, the body is replaced by
the term <number> or <num>. Here you must enter a nu-
merical value. <number> can be entered in any format
you like e.g. 1.23 can also be entered as
7
0.000000123 10 or 1230000

digits than the counter needs, your entry will be trun-
cated. The counter will stop if an entry is out of the count-
ers range. To proceed, the status message 'Program-
ming error' must be reset, see 'Status byte'.

Selecting Output Separator

Output separators terminate messages from the counter
to the controller. The separator needed is different for dif-
ferent controllers; see the Operators' Manual for your
controller.
At power on, the output separator of the counter is line-
feed 'LF' (10 ).
decimal
The output separator can be changed by sending SPR
<number> to the counter. <number> is the decimal
value of the ISO (ASCII)-code for the desired separator.
It can be 0-26, 28-31, ESC code, 27, is not accepted.
Only one <number> can be entered as separator. If you
want the combination of CR+LF (13
lected by 'SPR 255'.
EXAMPLE:
SPR 13 changes the output separator to CR
SPR 255 changes the output separator to CR+LF
The counter can signal EOI together with the last output
separator in responses and output data.
EOI ON switches on the function.
EOI OFF switches it off.
Default setting is EOI OFF.
The selected separator and EOI will not be altered by
LOCAL from the front panel nor by LOCAL or 'Device
clear' from the bus.

How to Select Function

Standard Functions
Functions are selected by sending the appropriate func-
tion command to the counter, e.g. FREQ A. The space
between FREQ and A indicates the input separator that
you always must insert.
Function Command
Frequency A FREQ A
Frequency FREQ B
B*
Frequency A/A —

Frequency A-A —

RPM A RPM A
Period A PER A
Totalize A

Pulse-width A WIDTH A
The function cursor on the display of the counter will
jump to the selected function.
Only possible if Input-B option, PM 9608B is installed.

Selecting Measuring-Time

The Measuring-time can be set to any value between
10 ms and 10 s, or SINGLE-measuring. Any value be-
low 10 ms will be interpreted as SINGLE. Values above
10 s will be out of range and cause an error. The pro-
gram command is MTIME <number>. Always enter the
Measuring-time in seconds. The entered value will be
trunkated to the nearest 10 ms increment.
Meas Command

0.2 s MTIME 0.2
10 ms MTIME 0.01
7.34567 s MTIME 7.34567 The Measuring-time will be

25 s MTIME 25.0
Comment
Default
Make a FREQ A
measurement and then
perform the ratio calculation
in the controller.
Make a FREQ A
measurement and then
calculate the frequency
difference in the controller.
See 'Totalize start/stop'.
The counter will also accept
PWIDTH A.
Comment
Default
You will not be able to see the
gate indicator blinking if the
Measuring-time is below 50 ms
7.34 s.
Out of range. Measuring
time will be SINGLE.
A display time of 50 ms is
set so that you can see the
Gate-indicator.
Out of range and error, the
counter will stop. It can
indicate programming error
by sending an SRQ if
selected in the SRQ-mask.
