Communications Flow
Processor Model (B01)
Note:
The device has a UART subset as well as GPIO (4 pin UART (tx/rx/rts/cts)
If needed, use the GPIOs for additional UART signaling.
The USB port can switch between a connection to the radio (red dotted line) or a connection to the
processor (green x line). The USB selection is controlled via programming on the processor. There is
no USB between the radio and the processor.
Communicating with the Device
Following are three options for communicating with the device.
Install USB drivers and plug into the micro USB connector. No need for a host board.
Access the device's USB interface via pins 6 and 7 of the 40-pin connector. Data pins 6 and 7 are in parallel
with the micro USB connector on the device. There is no connection to pins 6 and 7 on the developer board.
Establish serial communication using Multitech developer board MTUDK2. See the
Universal Developer Kit
2.0 Developer Guide
(PN S000610) for more information.
Dual Carrier Firmware for Cellular Radio
This device uses a cellular radio with dual carrier firmware meaning that it can be used on different carrier
networks (not simultaneously). The device can be used on either the Verizon or AT&T/other networks. The device
is configured for AT&T/others by default.
To check that your device is configured for the desired network:
AT#FWSWITCH?
If response is:
#FWSWITCH: 0
The device is configured for AT&T/other networks.
If response is:
#FWSWITCH: 1
