Default Button: Restore the default setted parameters. Insert the penpoint into the hole to press the
button for about 1 second, the internal Flash memory parameters will restore to factory default
parameters: IP = 192.168.0.250, Username = admin, Password = admin. When you forget the IP
address,user name or password, you can restore to the factory default parameters,and then reset
the parameters.
RS485 Interface: RS485 interface is the DB9M-pin plug which meets the Siemens S7-200 Series
PLC PPI interface technical specifications, the signal array match S7-200 series PLC PPI
interface, and has a 0.5 meter cable, you just simply plug the DB9M directly into the S7-200PLC
PPI interface outlet.

RS485 communication mode selection switch: you need to set the local connection as “modem
connection” in the STEP7 Micro/WIN software when you use the ES-ETH-PPI . At this time, you
need to choose 11-bit or 10-bit data communication mode.
