Pharos GPS-500

Device Set Up on Linux

• Plug in GPS-500 device to a USB port
• Search for device on computer

lsusb

This command should result in a finding the Prolific Tech. line as seen below.

example output:

Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub Bus 005 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub Bus 003 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub Bus 002 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub Bus 004 Device 008: ID 067b:aaa0 Prolific Technology, Inc. Prolific Pharos Bus 004 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub

• Search for a tty device

ls /dev

Look for a tty device: ttyUSB0 or ttyUSB1 or any other ttyUSBx, which depends (This was done on Fedora, other OS's may have a different designation)

View Data

• You may need to use sudo to allow permissions to the tty.
• This command will output troubleshooting info from the server process.

• This command will set the device to allow you to log data via tail or cat

stty -F /dev/ttyUSB0 cs8 4800 ignbrk -brkint -icrnl -imaxbel -opost -onlcr -isig -icanon -iexten -echo -echoe -echok -echoctl -echoke noflsh -ixon -crtscts

• View raw data after stty command

cat /dev/ttyUSB0

• Log Data - You will need to manage the log file sizes

cat /dev/ttyUSB0 >> gps_log

• Log Data with Filter - This significantly cuts down on the number of strings and is really the only string you need.

cat /dev/ttyUSB0 | grep GPRMC >> gps_logs
