[DB600] General instruction manual

Caution
Make sure to connect/disconnect the USB engineering cable to/from
the engineering port of the instrument while the instrument is
energized.
Note that the engineering port is designed for temporary connection
for communication, not for constant connection.
To enable the always-connected situation, specify the specification
with communication interface at the time of purchase, and use the
terminal at the back of the instrument for permanent connection.

Specification with communication interface
Select the specification with communication interface to perform constant communication.
The type of communication can be selected from RS485 and RS422A (DB650/DB670 only).
Data collection (Data Read) and parameter setting (Data Write) can be performed by connecting with a
PC. Remote operation or data management using a PC is also possible.
In addition, there is a communication transmission (digital transmission)/communication remote (digital
remote) function. This function enables a remote operation that produces no error by making the main
device execute SV transmission and the sub device receive it as remote SV via communication. The
remote operation by remote signal input is called analog remote, whereas the remote operation by
communication remote is called digital remote.
When the instrument receives the first remote SV data, "REM" lights on the operating condition display
and the digital remote status is entered.
To perform communication transmission or communication remote, the main and sub devices need to
have the same communication transmission rate, protocol and character settings.
