EMPower Connect™ Service Tool
Monitoring operation and manual control of the pump can be accomplished using the service tool
EMPower Connect which is part of the EMP Service Suite available at no cost on our website at:
http://www.emp-corp.com/support/downloads/ . To use EMPower Connect download and install on
your PC. If the pump is being run standalone you will also need an interface cable from the 6 pin
Deutsch connector on the pump and an EMP USB/TTL converter. Both are available as a kit P/N
7500038001. If the pump is on a J1939 CAN bus EMPower Connect™ can be run using a Data Link
Adapter (DLA) to interface to the CAN bus.
