Input type:
Photocoupler isolation
Shared common (DI-COM)
Allowable input voltage range: 0 to 10V
Note: Do not apply voltage outside the
allowable input voltage range
across input terminals. Doing so
can cause a malfunction.

Connecting to the USB Port
A USB2.0 port (mini B type) is available.
Using a dedicated protocol, you can operate and configure
the GM10 and output data.
Connecting to the Ethernet Port
Checking the Connection and Communication
Status
You can use the indicators that are located above the GM10
Ethernet port to check the connection status of the Ethernet
interface.
