Power Supply
The MMU su5 VDC power for digital circuitry to con-
nector P1. If input 1 or 2 uses a preamplifier, then the 24 VDC
I/O supply must be connected to the E1 terminal of the termi-
nation unit. That power goes to the DSM through the termina-
tion cable to edge connector P3.
Connector Functions
The DSM has 3 standard edge connectors along the rear of the
circuit board. The 12 pin connector (P1) supplies the module's
+5 VDC logic power from the MMU backplane. The 12 pin con-
nector on the lower side of the module is (P2). It connects the
DSM04 to the expander bus through a 12 strap dipshunt
mounted on the MMU backplane. The 8 input signals flow into
the 30 pin connector (P3) through a termination unit cable
from the termination unit.
