PMC-4U Front Panel IO Pin Assignment
The figure below gives the pin assignments for the PMC Module IO
Interface on the PMC-4U. Also, see the User Manual for your carrier board
for more information. GND* is a plane which is tied to GND through a
1206 0Ω resistor. AC or open are options – contact Dynamic Engineering.
