Introduction
This design guide is intended to provide a good understanding of the functionality of the OEM200 module.
The intended audience is the engineer responsible for integrating the OEM200 into a product.
Description and Specifications
The OEM200 is a component of the Sensicast A2400 Wireless Sensor Network Platform – a completely self-
configuring, self-healing, power managed sensor network.
Powered by SensiNet (Sensicast proprietary mesh networking software), the OEM200 is the most reliable mesh
networking radio module on the market today. With its external radio amplification stage, it has a range of
over 1000 feet (outdoors) and 230 feet (indoors, non-line of site). Furthermore, SensiNet uses frequency
diverse radio algorithms to ensue reliable, clear channel communication even in the most harsh radio
environments.
In addition, off-the-shelf A2400 infrastructure hardware and SensiMesh
®
Gateway software for constructing
and maintaining your mesh network is available from Sensicast.

Antenna
There is a PCB “Inverted F” antenna on the device. For best performance, care should be taken to keep metal
components away from this section of the PCB. The PCB will also support an external antenna connector at
J2. However, please note that this product is only FCC certified with the existing embedded antenna. If a user
application requires an external antenna, re-submission with the specific external antenna is required for FCC
approval. For more details, please contact Sensicast.
Radio Transceiver
The radio is under control of the OEM200’s microcontroller and is contained inside the metal shield.
Microcontroller
The SensiNet software, including the sensor API, runs on this microcontroller. It includes onboard flash
memory, RAM, and analog and digital I/O and a 32kHz real time clock.
LEDs
There are three LEDS: red, yellow and green that are firmware controlled.
