Configuring IP Address and Environmental
Variables
3.1.
IP Address and Environmental Variables
For TCP/IP communication, you must set IP address related items. In addition, you have
to set serial port related items (baud-rate, data bit length, parity bit, flow control, etc) to
EZL-200L.
You can set the IP address and the serial port related items by using ezConfig, the
supplied configuration utility which allows you to configure your EZL-200L over the
network, or by using AT commands in ATC mode.
