for each OEM board for a diagram of the positioning of any connectors.

For all ICE daughter modules, the circuit boards are designed such that all I/O connectors will be on a
single side, and the copper heatsinking tabs will be on the opposite side. The master controller (ICE-
MC1) also follows this convention, with the exception being the serial port flat flex connector.

Ultra-Miniature Coax Connector (UMCC)

The surface mount UMCC connectors (

Molex PN: 0734120110

) are used on the 

ICE-CS1

 and 

ICE-CP1

for handling low-frequency analog signals (<8 GHz). A UMCC to UMCC cable or UMCC to SMA cable
may be used to integrate these connectors with the OEM system.
