Restart:
Timer B is restarted during data transfer to allow the reception of data blocks of variable lengths.
Stop:
Timer B is stopped on the reception of the <ETX> signal.
Timeout: When a timeout occurs, the received data (command) are discarded. The device
then assumes its initial state and is ready to receive a new command.
The timeout value of timer B is set firmly to 15 seconds.
6.1.3 Terminal assignment of the optional IEEE488 interface
6.1.4 Control via the optional IEEE488 interface of the
RESISTOMAT
®
2329
For the device to be controlled via the IEEE488 interface, the IEEE488 option must be selected in the interface
menu (chapter 5.4.4.6). However, this is only possible if the IEEE488 card has been installed.
Setting the device address
The device address of the RESISTOMAT
®
model 2329 for control via the IEEE488 is set in the corresponding
interface menu. A number in the range 0...30 can be selected for the address. The default setting 9 is used in
all the examples here. Every device connected to the IEEE488 must have its own address. If the address of a
device is changed on the front panel, the new address becomes effective immediately.
The 24-pole IEEE488 bus con-
nection plug is standardized
and has the indicated pin asign-
ment.
To comply with applicable in-
terference protection guidelines
(e.g. VDE 0871B), all interface
cables and plugs must be
shielded and grounded at both
ends.
These are "Open Collector"
outputs.
