The PXI-2527 has a front-mounting terminal block (TB-2627). Bare wire is used to connect to the TB-2627 screw terminals. Using additional bare wire, you can externally connect (daisy-chain) the COM lines together to expand the multiplexer across multiple PXI-2527s. Remember to select the wire gauge so you can insert more than one wire in the COM screw terminals.
Spec'd clamp opening size: 0.065 x 0.067 in (1.65 x 1.7 mm)
Spec'd maximum wire diameter (for one wire): 0.65 in (1.65 mm)
