INTERFACE UNITS
IF-60RU IF-60GP
B71-0011-00
This instruction manual describes the procedures of installing the Interface Unit IF-60RU or IF-60GPfor our PSF Series
Power Supply Units. Refer to the instruction manual of the PSF series power supply unit for the usage of the PSF
series with the interface unit built in.
1. Installing the Interface Unit
Follow the instructions shown below and install the interface board properly with great care.
(1) Disconnect the AC power cable from the power supply unit. Make sure that the power switch is set to the Off
position and all display units are off.
(2) Remove two screws ②from the blank panel ①on the rear panel of the power supply unit, and detach the blank
panel.
(3) Insert the interface unit into the slot with care in the proper direction.
NOTE: Do not put any objects into the power supply unit during installation of the interface unit. Never turn on the
power supply unit if some objects should enter it.
(4) If the interface unit is not installed at the proper position, the screw positions are incorrect. Retry installation from
the beginning.
(5) Fix the interface unit with the screws removed from the blank panel in step (2).
(6) Connect the AC power cable, turn on the power supply unit, and check if the model name of the interface unit is
displayed. The interface unit is installed properly if its model name is displayed.
(7) Refer to the instruction manual of the PSF series power supply unit for the normal setting and control procedures.
2. Uninstalling the Interface Unit
Follow the instructions shown below and uninstall the interface board properly with great care.
(1) Disconnect the AC power cable from the power supply unit. Make sure that the power switch is set to the Off
position and all display units are off.
(2) Remove two setscrews ②from the interface unit. Uninstall the interface unit.
NOTE: The interface unit is plugged in the connector firmly. It may be uninstalled easily with the GP-IB or
RS-232C connector plugged with the unit.
3. Setting Local Bus Termination
When a local bus is used, it is necessary to connect termination resistors with both ends of the communication path
for impedance matching of the communication lines. The interface unit has termination resistors, which may be
selected by short-circuiting (ON) or opening (OFF) the jumper pin (CN2). Note that operation may become
unstable if there are termination resistors are in the middle of the communication path or no termination resistors
are connected with both ends of the communication path.
The jumper pin (CN2) for the shorting connector is located in the position shown below. The shorting connector is in
the short-circuit condition at the time when the interface unit is installed. Remove the shorting connector from the
interface unit installed in the center.
The removed shorting connector may cause an error. Do not mount in the power supply unit in the condition where
a single pin is connected.
