Connecting the Data Interface Port
There are two connectors to interface the Boomer II OEM Modem with
your device.
q RF Connector (described in the next section), and
q Data Interface Port
The data interface port is used to interface the modem to a serial
computing device and a power supply. The power supply requirements
are described in the next section.
A flat 30-way Flexible Printed Circuit (FPC) cable 0.3mm thick with
1mm centreline spacing is used between the Boomer II OEM Modem’s
data interface port and your device.
The asynchronous serial interface on the Boomer II OEM Modem
operates at 3V and can be controlled by a wide variety of
microcontrollers and microprocessors. The modem can be connected
directly to a microcontroller or through a universal asynchronous
receiver/transmitter (UART) to a microprocessor data bus.
If the modem is to be connected directly to a PC or other RS232
device, an interface must be provided to convert the signal voltage to
the higher values required by an RS232 device.
