Introduction
The PRO-MUX-2 is designed to suit the majority of NMEA 0183 systems and is ready to go ‘out of
the box’ by simply hard-wiring the two mode inputs as required. The manually configurable basic
modes of operation include buffer modes, autoswitch modes, and combine modes. For all other
configurations, leaving the mode inputs floating selects the ‘web based’ user configuration mode.
The configuration tool allows full customisation of the PRO-MUX-2, and as the configuration tool is
web based it is compatible across all popular Operating Systems.
The PRO-MUX-2 supports a direct Ethernet connection to a PC without the need for a specialised
Ethernet crossover cable.
Installation Warnings
All warnings and notices must be followed to ensure the correct operation of the PRO-MUX-2.
Incorrect installation may invalidate the guarantee.
It is highly recommended that all of the installation instructions are read before commencing the
installation.
There are important warnings and notes throughout the manual that should be considered before the
installation is attempted.
Warning 1:
Accuracy.
The Actisense PRO-MUX-2 is designed to accurately transfer data from input to output. When the
PRO-MUX-2 is in a Basic Mode no data integrity checking is performed, therefore any incomplete,
inaccurate or corrupt data received on a PRO-MUX-2 input will be duplicated to the PRO-MUX-2
outputs. In contrast, PRO-MUX-2 Smart Modes do use the sentence checksum (if available) to
remove incomplete and corrupted data, however, the accuracy of the data fields in a valid sentence
still remains the responsibility of the NMEA Talker that generated the data.
Warning 2:
Installation and Operation.
This product must be installed and operated in accordance with the instructions provided. Failure to
do so could result in personal injury, damage to your boat and/or poor product performance.
Warning 3:
Installation Code of Practice.
When wiring the power supply to the PRO-MUX-2 ensure the isolation switch is off. Wiring the PRO-
MUX-2 while the connection is live may damage the PRO-MUX-2 and is in breach of the guarantee.
Any connection to a battery or power supply must meet the mandatory essential safety requirements
that may be imposed by local regulatory agencies.
All wiring should be in accordance with the requirements of the NMEA 0400 installation specification.
Warning 4:
Mounting Requirements.
Select a flat location to mount the PRO-MUX-2. Mounting on a contoured surface may cause damage
to the case.
Do not mount the PRO-MUX-2 while the device is powered, or the cable harness is connected.
Note that the connectors are unplugged easily when mounting or removing the PRO-MUX-2.
Software Updates
The PRO-MUX-2 units have built-in firmware which is held in flash memory, allowing quick and easy
upgrades using the latest Actisense Toolkit. It is highly recommended that the firmware is kept up to
date in the PRO-MUX-2.
The currently installed PRO-MUX-2 firmware version can be viewed on the PRO-MUX-2 Configuration
Tool ‘Home’ page in the ‘Main Application’ section. Details of the latest PRO-MUX-2 firmware version
release can be found on the Actisense website’s PRO-MUX-2
‘Downloads’
page.
