3 INTERFACE CHARACTERISTICS
RXD_A and RXD_B
These logic level inputs are the primary (A) and secondary (B) serial port receive
lines (data input to the module). This output meets the input/output pin threshold
specifications (see Absolute Minimum and Maximum Limits, page 37.) The baud rate
for the two ports is under software control.
TXD_A and TXD_B
These logic level outputs are the primary (A) and secondary (B) serial port transmit
lines (data moving away from the module). This output meets the input/output pin
threshold specifications (see Absolute Minimum and Maximum Limits, page 37.)
The baud rate for the two ports is under firmware control.
Reserved Pins
There are 8 reserved pins on the Copernicus GPS Receiver. For the recommended pin
connections for these reserved pins, see Table 3.1.
