To communicate using PuTTY

You can connect a computer to a controller's Local Access port and use PuTTY, a free open source terminal
emulation program, to:

Set the baud rate for Port S1 on the controller

Set controller properties, such as IP address and network information

Retrieve a Modstat
PREREQUISITES

A computer with a USB port

A USB Link cable
NOTE The USB Link driver is installed with an i-Vu® v5 or later system. But if needed, you can get the latest
driver from http://www.silabs.com/products/mcu/Pages/USBtoUARTBridgeVCPDrivers.aspx. Install the
driver before you connect the USB Link to your computer.
CAUTION If multiple controllers share power but polarity was not maintained when they were wired, the
difference between the controller's ground and the computer's AC power ground could damage the USB Link and
the controller. If you are not sure of the wiring polarity, use a USB isolator between the computer and the USB
Link. Purchase a USB isolator online from a third-party manufacturer.
