The mProm™ Module Interface (Getting Started)
Voltage must be supplied to the mProm™ Module via pins 19 and 20 on the interface header.
The mProm™ Module regulates its voltage on board, but must be supplied a voltage between
3.5-14 Volts. The table below outlines the 26 pin interface to the mProm™ Module. The
mechanical diagram that follows indicates where pin-1 starts.

Once power is applied to pins 19 and 20, primary communication through the mProm™ Module
will take place on pins 6 and 8. These pins are the buffered UART interface to the Module. This
UART interface is 3.3-Volt logic only. To communicate with a PC and RS232 Translator must be
used on the customer’s end device. The mProm™ Programmer Board, used for prototype
development, translates the UART signaling to PC levels. Innovative Wireless Technologies’
document “mPros™ Network Interface Specification” (version P10 or later) outlines the
communication protocol utilized on the UART plus the over the air communication protocols for
your peer-to-peer and mesh network configurations.
Once the UART link has been correctly initialized, your device can then utilize the mProm™
Module to communicate information wirelessly to other mProm™ Modules. This allows the end
user to quickly setup communication links between two or multiple devices. If communication
