PHD development harness
If simulating the I/O isn’t required, the PHD Development Harness is a simpler, more robust option
for application development. The cable contains Power, CAN, video, USB and serial connections for
application development, but all contained in the harness itself. See Catalog MSG33-5024-US, PHD
Accessories, for more information.
