3.1.1 User Connector Type

The connector on the 9602/9602N is a Samtec low-profile header connector, part number FTSH-110-01-L-DV.
This connector provides the ability for a stackable board to board configuration, allowing connection to the
host system motherboard.
Data sheets on these connectors can be found at:
A suitable motherboard female socket that matches this connector is the SAMTEC header part number CLP-
110-02-L-D.

3.1.2 User Connector Pin Allocation

The user connector is a 2-row 20-way header. Individual pin assignments are shown in Table 7 and the limits
for the digital signals are listed in Table 8. Multiple supply grounds are provided and all supply and supply
grounds are required to be connected to the power supply in order to limit the current on any one pin.
Multiple signal grounds are provided to reduce cross-talk.
