User Lines
The user lines connector, located on the GPIB-M interface rear panel, provides
several signals to increase your operating control of the supply. These signals are
dependent on the operator's design and uses. The operation of the auxiliary status
lines requires that you provide external Vcc and ground. To locate the connector,
refer to
Figure 2.4
,
Figure 2.5
,
Figure 2.6
and
Figure 2.7
. See
Figure 2.13,
“Schematic For User Line Interface” on page 42
and
Table 2.3, “User Line Pins,” on
page 40
for pin descriptions.
The user lines are optically isolated, open collector configuration. The input lines are
capable of sinking 10mA (with recommended 5V at input) up to a maximum of
90mA.
XT/HPD and XPD: The connector for the user lines is a standard 8-conductor RJ45
jack. The cable is supplied by the user.
XFR or XHR: The connectors are removable “wire clamp” terminal block style
connectors. Use shielded twisted pairs of 22-24 AWG wire for connections. Strip
0.2” (5mm) of insulation from the wires and clamp securely at the appropriate pin.
