9. Interface 

 

 

9.1.  Standard Serial Output 

The standard serial output with 0 to 20 mA can be connected to a device such as an 
A&D printer or remote display. The interface has no power source. Therefore, the 
external devices to be connected must have a power source. The setting values of the 
standard serial output are changed in the general functions 

Cl f01

 to 

Cl f04

. 

 

Type 

0 to 20 mA current loop 

Data bits 

7 bits 

Start bit 

1 bit 

Parity 

1 bit, even 

Stop bit 

1 bit 

Baud rate 

600, 2400 bps 

Code ASCII
