Power Requirements
Power comes in from 8 to 10 volts DC. The Fixed Reader uses
less than 2 amps. Intermec supplies 9 volts DC at 2.4 amps
from Intermec power supply, #351-066-001.
User I/O
A general purpose I/O (Input/Output) connector provides signal
lines in and out of the reader allowing monitoring and/or con-
trol of external devices or functions.
The connector for this is a 13-pin female circular DIN. The
mating male connector you need for mating with this is a CUI
# SD-130, (one source is Digi-Key #CP-1013-ND).

GROUND though individual 10 ohm resistors
Outputs and inputs have 12 volt transient suppression devices
to ground at the connector. Output signals are driven by
2N3904 NPN transistors (low level) with a 100 kohm pull--up
to +5 volts through a silicon diode, giving about a 4.3 volt high
level. An output can be pulled high from an external source as
high as 40 volts. This will however tend to pull the other out-
puts higher (through two 100k resistors). The low level will be
about 0.1 volt up to about 30 mA. The output low voltage will
