Terminal Blocks
NOTE: Terminate field wiring in accordance with the appropriate 4100 Field Wiring Diagram (841-731).
Class A (Style D) Motherboard Terminal Blocks:
Two 8-terminal blocks (TBl and TB2) at the board’s top and two 8-terminal blocks (TB3 and TB4) at the board’s
bottom.
Class B (Style B) Motherboard Terminal Blocks:
One 8-terminal block (TBl) at the board’s top and one 8-terminal block (TB2) at the board’s bottom.
Connectors and Connector Sockets
J2 = Daughter Card Socket (for compatible daughter cards only).
Pl and Jl = lo-pin edge connectors. Pl fits into Socket Jl of the previous motherboard; Jl accepts Connector Pl
of the following motherboard. These connectors “daisy-chain” power, serial communications, and coded
signal outputs between motherboards.
l Pl-1 = TDX (Transmit Data)
l Pl-2 = COMMON
l Pl -3 = RCV (Receive Data)
l Pl-4 = CODE
l Pl-5 = 8VDC COMMON
l Pl-6 = 8VDC COMMON
l Pi -7 = +8VDC
l Pl-8 = 24VDC COMMON
l Pl-9 = 24VDC COMMON
l Pl-10 = +24VDC
P2 = 8-pin connector for 733-525 harnesses. Used by the first motherboard in each row for serial communications
and coded signal outputs.
l P2-1 = TDX (Transmit Data)
l P2-2 = COMMON
l P2-3 = RCV (Receive Data)
l P3-4 = CODE

From P8 of Master Controller board,.or P2 of
motherboard in previous row
