8. Serial Ethernet Recovery Flexcan (SERF)
Board and Development Harness
The SERF Development Board for the PHD is intended as a development tool to simulate inputs and
outputs when attached to a PHD display.
8.1. SERF Overview
The SERF Development Board allows the GPIO, CAN Bus, video and RS232 inputs and outputs to be
easily accessed without having to make a custom wire harness or build a special I/O board for each
development project. The SERF Development Board should be used in conjunction with the available
Power and I/O cables for PHD displays. See Catalog MSG33-5024-US, PHD Accessories, for more
information.

8.2. Available Inputs and Outputs
The SERF Development Board offers direct connectivity to the following Inputs and Outputs for the
PHDs.
•
5VDC, 12VDC and Ground connections
•
12VDC or 24VDC Power Supply
•
GPIO 1 through 10
•
RS232 Communication
•
CAN Bus 1 and 2
•
CAN Bus 1 and 2 Termination Resistor
•
Ethernet Communication (Reserved for Future Use)
•
Audio L and R, Input and Output (Reserved for Future Use)
In addition to the above I/O, the SERF Development Board has pin locations and power supplies to add
on a daughter board for matrix keypad or encoder inputs. The corresponding I/O is labeled on the SERF
Development Board. Note that “External” indicates the connection from the PHD to an external device
such as a PC, possibly through an adapter cable.
