Connecting the External Control Terminals

Terminal block

No. Pin name Operation

1 GND –

2 IN1

Starts/stops measurement, saves data les, aborts

measurement, enters events

3 IN2

4 GND –

5 OUT1

Outputs signals indicating judgments and status (error,

busy, waiting for a trigger)

6 OUT2

7 GND –

8 EXT.TRIG

The instrument is triggered when an external signal is

inputted as a trigger source.

9 TRIG.OUT Outputs a signal when the instrument is triggered.

10 GND –

11 EXT.SMPL Input a external sampling signal.

How to congure the external control terminal settings

On the [External terminal] screen, you can congure the following terminal: the external input (IN1,

IN2), external output (OUT1, OUT2), and trigger output (TRIG.OUT). Use the [Trigger] screen to

congure the external trigger (EXT.TRIG) setting.

Connecting the Instrument with computers

2.4 Connecting the Instrument with computers

Connecting the instruments with computers via a LAN cable allows computers to control and

monitor the instrument. Connect LAN cables to the 1000BASE-T connector of computers and

instrument. The procedures for connecting the cables (2 ways) are as follows.

(1) Connecting the instrument to the existing network

Connecting the instruments with a hub via LAN cables allows computers to control and monitor the

instruments.

• Model 9642 LAN Cable (optional)

(2) One-to-one connection of the instrument and a computer

Connecting the instruments with computers via a LAN cable allows computers to control and

monitor the instrument.

*: Use one of the following cables:

• 1000BASE-T compatible crossover cable (maximum length: 100 m)

• 1000BASE-T straight-through cable and crossover connector (maximum length: 100 m)

• Model 9642 LAN Cable (optional, coming with crossover connector)

CAUTION

When connecting the instrument to your LAN using a LAN cable of more than 30 m or

with a cable laid outdoors, take appropriate countermeasures that include installing a

surge protector for LANs. Such signal wiring is susceptible to induced lighting, which

can cause damage to the instrument.
