Host Communication

Host communication comes through the 9-pin female D-sub
connector. Both RS-232 and RS-422 standards are supported as
ordered from the factory or service center.

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 con­trol of external devices or functions.

The connector for this i s a 13-pin female circular DIN. The
mating male connector you need f o r mating with this is a CUI
# SD-130, (one source is Digi-Key #CP-1013-ND).

Definition

Outputs and inputs have 12 volt transient suppression devices
to ground at the connector. Output s ignals 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 out­puts higher (through two 100k resistors). The low level will be
about 0.1 volt up to about 30 mA. The output low voltage will

climb higher as the sink current increases. There is no protec­tion on this. You need to ensure that their load won’t require
thereadertosinkmorethan50mA.

Input signals should be 0 to +1.5 volt for a low input and +3.5
to +5 volts for a high input. Each input has a 1.1 kohm resistor
in series with clamping diodes, but only about 1PA is used until
the input exceeds the 0 to +5 volt input range. There is also a
weak (100 kohm) pull--up to +5 volt on each input.
