Introduction This design guide is intended to provide a good understanding of the functionality of the OEM100 module. The intended audience is the engineer responsible for integrating the OEM100 into a product. Description and Specifications The OEM100 is a component of the Sensicast H900 Wireless Sensor Network Platform – a completely selfconfiguring, self-healing, power managed sensor network.
Connectors The primary interconnection is P3, the 41 position board to board, header (Hirose p/n DF9A-41P-1V(20); mates with: Hirose p/n DF9A-41S-1V(20)) on the bottom of the assembly. Optionally, power can be brought to the board through P5, a two position, right angle wire to board, header (JST p/n S2B-PH-K-S, mate: JST p/n PHR-2).

Initialization: These pins are digital inputs and outputs used during the initialization of the module. Two-wire interface: Both SDA and SCK have 10K ohm pull-ups to VCC. The module acts as the master on the bus. UART: Two wire (RX/TX) or four wire (RX/TX/CTS/RTS) logic level interface. Runs at 9600 baud, 8 data bits, no parity, 1 stop bit. Reset: An active low signal (RESET#) to reset the microcontroller. Used during debug and test of the module.
Recommended PCB Layout The OEM100 occupies 2.35” by 1.58” and is designed to plug into a PCB mounted, 41 position, Hirose DF9 receptacle (Hirose p/n DF9A-41S-1V(20)). Please refer to Hirose’s documentation for more information about this connector. There are three mounting holes designed to accommodate 4mm plastic stacking posts (Richco p/n MDLSP1-04M-01).
Battery life Range Connector options Duty cycle Antenna LEDs Up to 3 years with a 2/3A Lithium battery using a 2 minute report interval (sensor dependent) Up to 1000’ (outdoors, line of sight) Up to 300’ (typical indoor conditions) Two (2) analog input lines Six (6) digital I/O lines Two wire interface bus UART (TX, RX, RTS and CTS) Remotely user-adjustable (default 3 minutes) Board mounted, omni-directional antenna included 3 diagnostic LEDs (red, yellow and green) 8
