28 Z-Sensor and Z-Eurocard Operation Manual
The default communciations parameters of the reciver are:
• 9600 baud
• 8 data bits
• no parity
• one stop bit
When first establishing communication, your interface must use this protocol. Having
established communication, you may send commands.
All the default data outuput commands are set to NO. The receiver will not output any
data until you send a message commanding it to do so.
If you have typed in and sent the command correctly, you should receive a response.
To become familiar with receiver messages, send a few common commands and
observe the responses.
Monitoring
The receiver provides the capability of monitoring receiver activity while data
collection is occuring. The following is a step-by-step instruction of how to access
important receiver status information such as:
• Satellite Tracking
• Position
• Remaining Memory
Satellite Tracking
If you wish to monitor the satellites the receiver is tracking and using for position
solutions, perform the following steps:
1. Send the NMEA command $PASHS,NME,SAT,x,ON
x—port designation
ON—turns port on
2. SAT messages will be output every second through the designated port.
3. The response message contains the number of tracked satellites as well as
whether individual satellites are used in the position solution.
Position
If you wish to view the current position of the Z-receiver, perform the following
steps:
