Attaching An Mb Series Backplane; Connecting Multiple Expansion Boards - Keithley DAS-8 Series User Manual

Attaching an MB Series Backplane

Refer to the MB Series User's Guide for information on connecting
DAS-8 Series boards to MB Series backplanes.

Connecting Multiple Expansion Boards

You can daisy-chain up to eight EXP-16, EXP-16/A, and/or EXP-GP
expansion boards to provide up to 128 analog input channels. You connect
the first expansion board to the DAS-8 Series board by attaching one end
of an S-1800 or C-1800 cable to the main I/O connector on the DAS-8
Series board and the other end of the cable to the J1 connector on the
expansion board. To connect additional expansion boards, attach one end
of an S-1800 or C-1800 cable to the J2 connector on the previous
expansion board and the other end of the cable to the J1 connector on the
next expansion board in the chain.
Note: Each EXP-16, EXP-16/A, or EXP-GP expansion board is
associated with an analog input channel on the DAS-8 Series board. You
specify the associated on-board channel by setting a jumper on the
expansion board. Make sure that you use a unique jumper setting for each
expansion board you are using. Refer to your expansion board
documentation for more information.
You can use the J2 connector on the last expansion board in the chain to
attach an STA-08/STA-08PGA screw terminal accessory. This allows you
to access the remaining functions of the DAS-8 Series board.
