Connecting method and internal equivalent circuit

CSD−814B

Corresponding instruments

to serial interface

● Corresponding instrument for serial interface, there are M250

Printer made by UNIPULSE Corporation and so on.

● As for cable, be sure to use 2−cores shielded wire as much as you can.

When shielded wire is not applied, make the cable twisted.(Cable

length is within 100 m when shielded wire is applied, and within 20 m

when shielded wire isn’t applied.)

● Corresponding instruments for serial interface can be connectable up

to 3 sets in parallel. (Depending on the instruments connected.

Maximum output current is approx. 20 mADC).
