6. GPIB Connector . A standard GPIB cable can be attached to this connector to allow
the instrument to be computer-controlled. See the “Programming Manual for -B
Instruments” for more details on GPIB control.
7. RS-232 Connector. A standard serial cable with a 25-pin male connector can be
attached to this connector to allow the instrument to be computer-controlled. A user
name (“admin”) and a password (“default”, as shipped from the factory) are required
when logging into a serial terminal session. The internal controller attempts to auto-
sense the parity setting. It may be necessary to send a few return characters before
attempting a login in order to provide enough data to allow this auto-sensing to work.
(A standard Linux “agetty” process is used to implement serial control internally.) See
the “Programming Manual for -B Instruments” for more details on RS-232 control.
8. Network Connector . This Ethernet connector allows the instrument to be remotely
controlled using the VXI-11.3, ssh (secure shell), telnet, and http (web) protocols. See
the “Programming Manual for -B Instruments” for more details.
9. PULSE OUT CONNECTORS . These two BNC connectors provide the pulse output
signals to the test jig. Both should be connected to the corresponding inputs on the
test jig using two of the the supplied coaxial cables (2 meters in length).
These connectors are wired in parallel internally. It does not matter which “OUT”
connector on the mainframe is connected to which “IN” connector on the test jig.
Caution: Voltages as high as 120V may be present on the center conductors of
these output connectors. Avoid touching these conductors. Connect to these
connectors using standard coaxial cables, to ensure that the center conductors are not
exposed.
10.CONTROL Connector . This DB-9 female connector should be connected to the
corresponding connector on the test jig using the supplied DB-9 cable. This cable
contains the safety interlock signals that ensure that the test jig lid is closed.
