Extension Header (Row Signal) Wiring for 4x64
The position of extension headers J24 and J25 are marked on the 34934T-001’s
silk-screen. Oriented with the terminal side of the board up, the pin numbers for
these headers are shown below.
The supplied 20-pin terminators are identical. For 4x64, you can only make row
connections to header J24. The terminal numbers—corresponding to the
headers—are shown below. Pay careful attention to the indexing keys on the
connectors, to correctly identify terminal #1.
You must fabricate custom cabling to make row signal connections to the central
16 pins (3-18) of header J24, using the pin assignments below. The supplied blue
terminators accommodate 22 AWG coated wire, fitted to “crimp-to-wire” contacts
with latch tabs (FCI part #76357-301LF or equivalent).
