Host Communication

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

S The maximum data rate is 115.2K baud, with 8 data bits, no

parity bit, and 1 stop bit.

S The maximum RS-232 distance from the reader to the host,

modem, or other physical controller interface is 50 feet (15.2
meters).

2 TXD (Transmit Data) to the host

3 RXD (Receive Data) from the host

5 Ground

7 CTS (Clear to Send) from the host

8 RTS (Re quest to Send) to the host

Power Requirements

Power comes in from 8 to 10 volts DC. Your 915 MHz Reader
uses less than 2.4 amps. Intermec supplies 9 volts DC at 2.4
amps from Intermec power supply, p/n: 851-067-001.

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.

mating male connector you need for mating with this is an In­termec p/n: 351-184-001.

9 through 13 Ground through 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 12 volts. This will however tend to pull the other out­puts higher (through two 100k resistors). The low level will be
about0.1voltuptoabout30mA.Theoutputlowvoltagewill
climb higher as the sink current increases. There is no protection
on this. You need to ensure that their load won’t require the
reader to sink more than 50 mA.

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 1 µAisusedun­til 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.

Installing the IM5 Reader Module

The IM5 Reader Module requires 8-10 volts DC at 2 amps.
The IF4 Serial Reader is powered through a 2-pin bulkhead bar­rel connector (Switchcraft p/n: 712A).

The Reader Module supplies 9-volt 2.4 amps to this connector.
Mating plugs for this connector are Switchcraft part numbers
760, 760K or 761K. A cable within the PSR connects the bulk­head barrel connector, via an endplate switch, to the 2-pin Mo­lex connector on the IM5 Reader Module.

The IM5 Reader Module has holes along the sides that can be
used for mounting. For best results, attach heat sink to case via
the screwholes in the heat sink.
