Example of connection

RS-422

RS-485



The polarity (A, B) of the host computer signal depends on the computer model.

Check the technical manual of the computer.

Data format

The data format for the RS-422/485 is the same as the RS-232C except the following:



When used with the function setting “

5if 1

” (RS-422) or “

5if 2

” (RS-485), set a

different address to each scale using the function setting “

adr

##”. ((##=01 to 99)



Start all commands with “@##” (## is the address of the scale to send a command).

All replies from the scale start with “@##”.
The format after “@##” is the same as the RS-232C, both in commands and replies.



When used with the RS-485 interface (function setting: “

5if 2

”), note the following:

•

When sending commands continuously, leave an interval of 500 ms or more

between commands.

•

Do not use stream mode (function setting: “

prt 0

”) when sending commands.

Commands will not be received correctly and will be invalid.

Connect TRM to RDB
at the farthest SW from
the host computer.
