defective power cable may result in electric shocks, electrocution, or
a fire.
󲨘
󲨘󲨘󲨘󳁣The fuse for protection󲨘
The product will not run if its input power protection fuse flows out.
The protection fuse is built in the product, and the user cannot
replace it. When the fuse blows out, contact our distributor without
opening the casing. The user must not open the casing or replace
the fuse arbitrarily. Disobedience to this instruction may result in
electric shocks, electrocution, or a fire.
󲨘
󲨘󲨘󲨘󳁣Changing the source voltage rating󲨘
The user cannot change the source voltage of the product. Contact
our distributor, if it is necessary to change the source voltage rating
marked on the product. The user must not open the casing or
change the source voltage rating. Disobedience to this instruction
may result in electric shocks, electrocution, or a fire.

󲨘
󳀴󲨘 Warning item on installation environment
󲨘󲨘󲨘󲨘󳁣Operating temperature
󲨘Use the product within the operating temperature indicated in the
rating column. If the product is used with the vents of the product
blocked or in high ambient temperatures, a fire may occur.
󲨘
󲨘󲨘󲨘󲨘󳁣Operating humidity
󲨘󲨘󲨘 Use the product within the operating humidity indicated in the rating

󳀴󲨘 When the product is left unused for a long time
󲨘󲨘 Be sure to remove the power plug from the outlet.
󲨘
󲨴Calibration󲨶
Although the performance and specifications of the product are
checked under strict quality control during shipment from the factory,
they may slightly change because of secular changes in its parts. It
is recommended to periodically calibrate the product so that it is used
with its performance and specifications stable. For consultation
about the product calibration, call the distributor or the company
where you bought the product.
󲨴Daily maintenance󲨶
When you clean off the dirt of the product covers, panels, and knobs,
avoid solvents such as thinner and benzene. Otherwise, paint may
peel off or the resin surface may be affected.
To wipe off the covers, panels, and knobs, use a soft cloth with
neutral detergent in it.
During cleaning, be careful that water, detergents, and other foreign
matters do not get into the product.
If a liquid or metal gets into the product, an electric shock and fire are
caused. During cleaning, remove the power cord plug from the outlet.
󲨘
Use the product correctly and safely, observing the above warning and
caution items.
Because this manual indicates caution items even in individual items,
observe those caution items to correctly use the product.
If you have questions or comments about the content of this manual,
call the company or our distributor.

1. GENERAL
The GP-600B adapter is designed to set the constant voltage and
constant current and control the OUTPUT switches and power relays
of the regulated DC power supply units, PS, PA-B, PD-A and PT series
from a computer through the GP-IB bus (in conformity to the
IEEE-488-1978).
- The GP-600B has an interface function in conformity to the
IEEE-488-1978.
The GP-600B also has an SRQ function to detect errors in the
power supply units for safety system control.
- The GP-600B converts digital signals through the GP-IB bus
into two channels (four references) of analog signals.
The GP-600B has two references per channel and can control
the voltage and current of the power supply units through a single
channel. Each channel of the GP-600B is isolated. A D/A
converter with 12-bit resolution is used for each reference,
allowing high-precision setting.

3. INSTRUCTIONS ON USE
󳁣Checking the power source
-Use the GP-600B on the source voltage rating.
󳁣Replacing the fuse, and changing the source voltage rating
-Contact our distributor if it is necessary to replace the fuse or
change the source voltage rating.
󳁣Ambient temperature and installation site
󲨘-Do not use the GP-600B in a place whose temperature and/or
humidity exceeds the rating.
󲨘-Do not use the GP-600B in a place with much dust or vibrations.
-Take noise reducing measures properly if there is a large noise
source around the GP-600B.
󲨘
󳁣Before turning on the GP-600B󲨘
󲨘-Complete all connections and make sure that connections are done
properly before turning on the GP-600B.
-Turn on or off power in the order shown in the drawing below.
-Do not plug or unplug any connector in the power on condition.

󳁣System interface󲨘󲨘
󲨘-Be sure to use control software applicable to the service requests
when the GP-600B is used with the service requests enabled.
󲨘-Give listen-only specification from the controller when the GP-600B
is used in the listen-only mode.
󳁣Output ripple noises
󲨘-When the GP-600B is connected with the regulated DC power
supply units, the DC power supply units may output more ripple
noises than those in individual operation. This is because the
cables lead to bad influences upon noises or the regulated DC power
supply units amplify ripple noises output from the GP-600B.
󲨘
󳁣Precautions for connection󲨘
-The GP-600B converts digital signals through the GP-IB bus into
analog signals with two D/A converters in two isolated channels and
outputs individual four-channel analog signals. However, do not
use the reference channels B and D in the floating condition. Such
operation does not guarantee the proper performances. Be sure
to connect the negative (-) output of the channel B with the negative
(-) output of the channel A and the negative (-) output of the channel
D with the negative (-) output of the channel C, when the channel B
and D are used individually.
󲨘

4. SYSTEM CONFIGURATION
4-1. Principle of Operation
󲨘Digital signals through the GP-IB connector are supplied to the
GP-IB interface IC through the bus transceiver.
The handshaking timing of this GP-IB interface conforms to the
IEEE-488-1978. Codes received by the GP-IB interface are
decoded by the CPU then. The CPU converts the data into
binary data and outputs to the D/A converters through serial
output ports. Those data pass through photo-isolators and are
isolated. The shift registers convert them into parallel data,
which are input to the D/A converters. The CPU also executes
controls of the control connectors and SRQ processing.
The block diagram of the GP-600B is as shown below.
