Testing The Serial Interfaces On The Processor Unit - Simrad ME70 Instruction Manual

Simrad ME70 Factory Acceptance Test
Testing the serial interfaces on the Processor
Unit
The ME70 Processor Unit offers a number of serial lines to communicate with external
devices. These interface capabilities must be tested.
Prerequisites
The ME70 has been set up with its hardware units connected as specified in the ME70
Installation manual.
• The ME70 system is turned on and operates normally.
• If applicable: The transducer is replaced with a dummyload.
• A personal computer with a sensor simulator program is connected to the Processor Unit.
The simulator is active.
You need the following test equipment:
• Personal computer
• NMEA Simulator software
Context
Refer to the relevant ME70 end user manuals for information about the serial communication
setup.
Procedure
1 Connect a serial line cable from the personal computer to the first serial port on the
Processor Unit.
2 Start the ME70 program.
3 Start the Sensor Simulator program.
4 Set up the relevant communication parameters for the first port to accept the sensor data.
The communication parameters defined for NMEA 0183 are:
• : 4800 bit/s
Baud rate
• : 8
Data bits
• : Even
Parity
• : 1
Stop bits
Some instruments may provide other parameters and/or options. You must always
check the relevant technical documentation supplied by the manufacturer.
