4. PCD-39E00 Terminal Board
4.1 Introduction
The PCD-39E00 is a Terminal Board that can be used with the iPac HCS12 as well as other products. This Terminal Board is
designed to be used stacked on top of the iPac using the supplied standoffs but can be alternatively used off to the side if the
user provides longer cables.
The PCD-39E00 comes with three cables of which only two can be used at one time. The HRD2 (Analog) connector is
always used if Analog connectivity is required whereas HDR1 and HDR3 are selectively used depending on the desired
connectivity. If HDR3 has the desired connectivity then use the short 50 pin ribbon cable. If HDR1 connectivity is desired
then the long twisted cable should be used. Note the twist needs to be intact.
If connectivity to both HDR3 and HDR1 are necessary then two PCD-39E00s will be required, one which uses the short 50
pin cable and the other that uses the longer 50 pin cable with the twist.
4.2 iPac Terminal Board Pinout
The PCD-39E00 can be used with several different board thereby changing the connector descriptions for each board. There
fore the specific iPac descriptions are given within the context of the iPac HCS12 manual. There are eight individual 10 pin
screw terminal connectors used on the PCD-39E00. Each is labeled STx where x is numbered from 1 to 8. The diagram
below shows the connector layout.
