Emulator Version Communications Protocol
The Emulator Version of the RS485 modem is ideal for customers who are already using NCD wireless sensors
and wish to adapt existing RS485 messages to follow NCD standards for device communications. The
Emulator version essentially takes incoming RS-485 data and attaches additional information to make existing
equipment act like a modern NCD IoT sensor. The Emulator Version also accepts similarly formatted messages
over wireless and sends only the payload to the RS485 network. The Emulator Version is among the easiest of
the RS485 Modem versions we currently offer, and is an ideal choice for PLCs with limited resources to
communicate effectively with existing RS485 networks as well as existing NCD IoT sensors. The following
commands may be issued to the modem to simplify and enhance the adaptation of RS-485 communications into
a wireless protocol.
