he 46022-30 consists of the address logic and a power sup-
ply. Refer to Fig. 1.
Address Logic
The address logic consists of a series of OR, NAND, and exclu-
sive OR gates that are configured to lock out unselected data
addresses and thereby prevent a directed data transmit request
from being accepted. Once an address had been set by the mini-
DIP switches S1-1 through 5, only that data address will turn on
the front panel green LED labeled CHAN ENB. This indicates
that data is being sent to and from the MATs and CPMs through
the communication subassembly.
Power Supply
The power supply uses -21 to -56 VDC input power to supply
+12, -12, and +5 VDC to the modules circuit board and to the
optional subassembly. It also su12 VDC to pin 47,
-12 VDC to pin 49, and +5 VDC to pin 45 of the modules edge
connector. These can be used for off-board use.
