8: UART to RS232 Interface
Typically, an RS232 or USB interface is required to connect the PC to the Sierra
Wireless GNSS module for communication. Most Sierra Wireless modules use a set
of communication ports in TTL-logic. A bridge IC may be needed for RS232 signal
conversion.
The supported baud-rates are 460800 and 115200 bps.
Please refer to the reference circuit in
Figure 8-1
below for RS232 signal conversion.
An SP3220E IC is used here as an example.
