Antenna Connector
The connector for antenna is a standard reverse SMA jack. Simply connect it to a 2.0dBi dipole
antenna (Standard Rubber Duck) and it is 50 Ohms impedance and can support 2.4GHz frequency .
Ethernet Port
The connector for network is the usual RJ45. Simply connect it to your network switch or Hub. When
the connection is made, the green color LED of Ethernet port will light on. When data traffic (Rx/Tx)
occurs on the network, yellow color LED will blink during data transferring.
Serial Port of RS-232/RS-422/RS-485
Connect the serial data cable between the WPC-832-4 converter and the Serial interface device.
Follow the web page parameter setup procedures to configure the converter.
