7. REMOTE CONTROL
The model 6622T Automatic DCC Thermometry Bridge series operates directly from the front
panels or under remote control of the computer supplied with the system. Remote control can be
interactive, with the user controlling each step from a terminal (not supplied with the system), or
under the control of the computer running the model 6622T as an automated system with the use of
the BridgeWorks Data Acquisition Software.
This chapter describes the IEEE-488 interfaces and the commands to which the model 6622T will
respond. A detailed description of the remote control command set is included in Section 5.5 of
this manual.
WARNING: In general, local control from the front panels should be performed only when
remote control is inactive. This occurs when the BridgeWorks Data
Acquisition Software is either closed or displaying an error message. During
remote control, the front panel controls, particularly those of the model 6622T,
may appear to be inactive, due to the frequency of communication by the
computer system, which acts as the GPIB controller.
7.1. INTERFACES
The model 6622T system has an external IEEE-488 interface.
The IEEE-488 connector is mounted on the rear panel of the model 6622T bridge. This connector
can optionally be daisy chained together to other components such as the 6664A and 6664A-2A
Scanners as well as to connect to the IEEE-488 connector of the computer system.
The factory settings for the IEEE interface are shown in the Table 5-1. The factory setting also
includes a set bus speed for the controller of 2 usec.
7.2. IEEE-488 (GPIB) INTERFACE
The model 6622T is fully programmable for use on the IEEE 488 interface bus (also known as the
General Purpose Interface Bus (GPIB)). The model 6622T interface is 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 model 6622T is operated on the
IEEE-488 bus as a talker/listener. This manual assumes that the user is familiar with the basics of
the IEEE-488 interface bus.
