Try using Port A for communication as only pins 2, 3, and 5, which
the only pins required for communication are connected. Port B
also offers the event marker input and the 1 PPS output signals.
6. Make sure that the baud rate of the Seres matches the other
device. The other device must also support an 8 data bit, 1 stop
bit, and no parity port configuration (8-N-1). Some devices
support different settings that may be user-configurable. Ensure
that the settings match.
7. Consult the troubleshooting section of the other devices reference
manual to determine if there may be a problem with that
equipment.
Q - Am I able to configure the two serial ports with different baud rates?
A - Yes, the ports are independent. For instance, you may have one port
set to 4800 and the other to 19,200, or vice versa.
Q - Am I able to have the Seres antenna output different NMEA messages
through the two ports?
A - Yes, you may have different NMEA messages turns on for the two
serial ports. Further, these NMEA messages may also be at different
update rates.
Q - How can I determine what the current configuration of the Seres is?
A - The $JSHOW<CR><LF> command will request the configuration
information from the Seres’ internal GPS engine. The response will be
similar to the following output and is described in detail in Chapter 6.
$>JSHOW,BAUD,19200
$>JSHOW,BIN,1,5.0
$>JSHOW,BAUD,4800,OTHER
