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).
RS-232 Connections
Pin Number Definition
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 (Request to Send) to the host
Power Requirements
Power comes in from 8 to 10 volts DC. Your 865-868 MHz
Reader uses less than 2.4 amps. Intermec supplies 9 volts DC at
2.4 amps from Intermec power supply, p/n: 851-067-002.
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.

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.

Connecting and Getting Started
CENELEC regulations limit exposure to
radiofrequency (RF) radiation. To comply with
these regulations, operators of this device must
maintain a distance of at least 20 cm. (8 inches)
from the cover on the antenna assembly (The cover
on the antenna is the dome shaped surface). While
the device is on, the operator ’s body and parts of
the body such as eyes, hands, or head, must be 20
cm. (8 inches) or farther from the cover of the
antenna assembly.
CENELEC regulations also require that the
antenna assembly of this device be installed in
accordance with the installation procedures to
allow the operator to comply with the limit. Use of
antennas and accessories not authorized may void
the compliance of this product and may result in
RF exposures beyond the limits established for this
equipment.
Antenna Installation
Ensure that you read the above warning before installing the
antennas and using your Reader product.
