Pin assignment of the multipin connector
The 40 lead multipin connector is the main connector for all of Spectrum’s digital boards and is addi-
tionally used for different options, like “Extra I/O“ or the additional digital inputs (on analog acquisition
boards only) or additional digital outputs (on analog generation boards only).
The connectors for all the options are mounted on an extra bracket, while the main conncectors for the
digital boards are mounted directly on the board’s bracket. Only in case that a digital board uses more
than two connectors (more than 32 in and/or output bits) an additional bracket will be used for moun-
ting the connectors as well.
The pin assignment depends on what type of board you have and on which of the below mentioned
options are installed.
Extra I/O with external connector(Option -XMF)
A3…A0 are the pins for the analog outputs, while D23…D0 are the 24 digital I/Os.
Pin assignment of the multipin cable
The 40 lead multipin cable is used for the additional digital inputs
(on analog acquisition boards only) or additional digital outputs (on
analog generation boards only) as well as for the digital I/O or pat-
tern generator boards.
The flat ribbon cable is shipped with the boards that are equipped
with one or more of the above mentioned options. The cable ends
are assembled with a standard IDC socket connector so you can ea-
sily make connections to your type of equipment or DUT (device un-
der test).
The pin assignment is given in the table in the according chapter of
the appendix.
