Connecting The Controller; Giving The Counter An Address; Checking The Communication - Fluke PM6669 Operator's Manual

Page: 22
Remote/Local, RL1
You can control the counter manually (locally) from the
front panel, or remotely from the controller. The LLO, lo-
cal-lock-out function, can disable the LOCAL button on
the front panel.
Parallel Poll, PPØ
The counter does not have any parallel poll facility.
Device Clear, DC1
The controller can reset the counter, forcing it to default
settings, via interface message DCL (Device clear) or
SDC (Selective Device Clear).
Device Trigger, DT1
You can start a new measurement from the controller
via interface message GET (Group Execute Trigger).
Bus Drivers, E2
The GPIB interface has tri-state bus drivers.

Connecting the Controller

The bus interface connector is on the rear panel of the
counter. If your counter does not have any connector,
you must install the GPIB-interface option.

Connect the controller via an IEEE-488 cable to the bus
connector. If you use IEC-625 cables, an adapter is
available, see ordering information at the end of this
manual.

Giving the Counter an Address

The counter must have a unique address so that the
controller can communicate with it. The address is se-
lected by setting switches to the binary equivalent of the
address you want. The switches are located to the right
of the interface connector. The OFF position means 0
and the ON position means 1.

* Factory setting.
NOTE: 31 is the bus command for "Untalk" and should
not be used. If 31 is selected the counter will
work as if address 0 is selected.
Talk-Only
The leftmost switch in the address switch block is the
TALK ONLY switch. If you set it to '1', the counter will
output measurement results on the bus continuously. It
will not react to any incoming commands.
This setting may only be used if the counter is con-
nected to a 'Listen only' device such as a printer. Set the
switch to '0' when you want normal bus communication.
Talk only is set to '0' on delivery.
The counter is now ready for bus control.

Checking the Communication

To check if the counter and the controller can communi-
cate, address the counter and execute the following se-
quence: (The programming example is for an HP-85
controller.)
Type on Controller:
REMOTE 710
OUTPUT 710;"ID?"
ENTER 710;A$
DISP A$
If everything is OK, the counter will identify itself as:
PM6669/YZW/MN
where:
Y = 4 if the counter has an HF-input, otherwise 0.
Z = 3 for MTCXO, otherwise 1
W = 6 (GPIB-bus is installed)
M = Revision No. of counter firmware
N = Revision No. of GPIB-bus firmware

This Should Happen.
The remote indicator should
be switched on.
Ask for the counter identity.
Input result from counter.
The response on the
display of the controller is
the identity of the counter.
