INTRODUCTION RS485 TO WIRELESS
The NCD RS-485 to Wireless Adapter converts data in both direction between Wireless and RS-485
communications. Inside the modem, you will see a small module, which actually handles the conversion
process. This documentation will reference this module and all applicable jumper settings.
There are 3 versions of this modem, which will be covered in this guide. The communication protocols are

protocol for all 3 versions. Please note this guide will discuss commands in hex values ONLY.
Also, please note the default RS-485 Communications Baud rate is 9600. We suggest using the default settings
for best results.
Getting to Know NCD RS-485 Node Modules
NCD RS-485 Node modules are a modular technology, allowing most NCD devices to be retrofitted with RS-485
communication capabilities. Node modules have a number of options an
