The data transfer rate determines how fast information is transmitted. Take for example a log
whose message byte count is 96. The default port settings allows 10 bits/byte (8 data bits + 1
stop bit + 1 framing bit). It therefore takes 960 bits per message. To get 10 messages per
second then requires 9600 bps. Also remember that even if you set the bps to 9600, the actual
data transfer rate may be lower and depends on the number of satellites being tracked, data fil-
ters in use, and idle time. It is therefore suggested that you leave yourself a margin when choos-
ing a data rate.
The minimum suggested baud rate for most applications is 115200 bps for GNSS only or
230400 bps for GNSS+INS. If the buffer overrun flag is present in the RXSTATUS log,
(refer to the
rate if possible, or change to a medium supporting higher bandwidth (Ethernet).
Although the receiver can operate at data transfer rates as low as 300 bps, this is not
recommended. For example, if several data logs are active (that is, a significant amount
of information needs to be transmitted every second) but the bit rate is set too low, data
overflows the serial port buffers, causing an error condition in the receiver status that
results in lost data.
The following ports are supported and can be configured using the commands listed. Refer to the
commands listed in the
tions.
Receiver Type
SMART7
Change the COM Port Settings
To change the settings on a COM port, use the SERIALCONFIG command. For example:
To change the data rate of COM2 to 115200, enter:
l
SERIALCONFIG COM2 115200
To change the data rate of COM1 to 57600 and enable even parity, enter:
l
SERIALCONFIG COM1 57600 E
Communicating using a Remote Terminal
One method of communicating with the receiver is through a remote terminal. To communicate
with the terminal, the receiver requires only the RX, TX and GND lines be used. Ensure the ter-
minal's communications set up matches the receiver's port settings.
