the serial device or communication between the device and the
ADAM-4570 fails, the “Device Idle” function will switch the
communication port from one port to another port to keep com-
municating with another device automatically. Thus, another de-
vice can send data to the ADAM-4570.
Auto-reconnect after networking breaks
Sometimes, the system crashes because the ADAM-4570/
ADAM-4571/EDG-4504 is interrupted or powered-off by ac-
cident. The ADAM-4570/ADAM-4571/EDG-4504 provides
an “Auto-reconnect” function to solve this problem. When the
ADAM-4570/ADAM-4571/EDG-4504 is powered-off acci-
dentally, the driver will keep trying to reconnect the ADAM-
4570/ADAM-4571/EDG-4504 automatically. When the
ADAM-4570/ADAM-4571/EDG-4504 recovers or is pow-
ered-on, due to this auto-reconnect function, the host PC can
send commands to the ADAM-4570/ADAM-4571/EDG-4504
again. This function enhances the reliability of the system.
Auto-detect Ethernet Data Gateway products
The configuration utility can search all the Ethernet Data Gate-
way devices on the network automatically and configure them
according to the current network status, saving your effort to
acquire the status information yourself.
Easy to diagnose the communication situation
If this test item is selected, an internal test will be done on the
RS-232 serial port, and the result (successful or failed) will be
displayed when the test is completed. If this test item is selected,
an external test will also be done to check that the connection
signals for each port are working properly. For the external test,
you will need to connect each port to a loopback tester. The test
