This guide will use AT commands using a terminal applications such as Hyper Terminal or Putty
You should already be familiar with sending AT commands to the CalAmp device using a terminal software.
You should also enable Terminal Window in the application to be able to monitor the data between the CalAmp device and GpsGate Server.

Enable support in Gpsgate Server:
1. Login to SiteAdmin
2. Click Plugins
3. Install "CalAmp" v184.108.40.20605 or newer
4. Install "Garmin"
For full Chat and Dispatch support you need Chat and Dispatch as well.
