5. REMOTE CONTROL
The 6530 TeraOhm Bridge-Meter operates directly from the front panel or under remote control
of an instrument controller, computer or terminal. Remote control can be interactive, with the
user controlling each step from a terminal, or under the control of a computer running the 6530
in an automated system. It is also possible to connect a printer to the remote interface of the 6530
and have the 6530 output some or all of the measurements taken to the printer for a permanent
record.
This chapter describes the interfaces and the commands to which the 6530 will respond. The
setting of the IEEE-488 address and mode is described in OM6530 Section 5.8.1.
5.1.
INTERFACES
The model 6530 has two interfacing standards available:
•
A parallel interface conforming to IEEE-488.2.
•
A serial interface conforming to RS-232C.
The IEEE-488 connector is mounted to the rear panel. The IEEE-488 address defaults to a
factory setting of 04. This setting can be viewed and set to a valid address using the front panel
controls.
The RS-232C connector is mounted on the rear panel but it has to be configured from the front
panel.
The 6530 can be operated in a system where both RS-232C and IEEE-488 interfaces are being
used. It can be controlled with an IEEE-488 bus and a printer connected to the RS-232C output
for permanent records of measurements.
In a system containing more than one controller, only one controller can exercise control while
the other stays in dormant state until control is transferred.
5.2.
IEEE-488 (GPIB) INTERFACE
The 6530 is fully programmable for use on the IEEE standard 488.1 interface bus (also known as
the General Purpose Interface Bus (GPIB). The interface is also designed in compliance with the
supplemental standard IEEE-488.2. Devices connected to the bus in a system are designated as
talkers, listeners, talker/listeners, or controllers. The 6530 can be operated on the IEEE-488 bus
as a talker or under the control of an instrument controller as a talker/listener.
