About the MS-3000 Decoder
The MS-3000 single head decoder, companion to Microscan’s MS-520 and
MS-1200 scan heads, is designed to accept high speed bar code data from
a scan head, translate that data into alphanumeric characters, and send
that data to a host or other terminal.

Warning and Caution Summary
Caution:There are no user serviceable parts in the MS-3000 decoder.
Opening the decoder voids the Microscan Systems warranty.
Note: The MS-520 and MS-1200 scan heads are designed to be con-
nected to the MS-2000 and 3000 decoders. When installed, powerfor
the scan head is provided by the decoder.
Caution:This equipment has been tested and found to comply with the
limits for a Class B digital device, pursuant to part 15 of the FCC Rules.
These limits are designed to provide reasonable protection against harmful
interference when the equipment is operated in a commercial environ-
ment. This equipment generates, uses, and can radiate radio frequency
energy, and, if not installed and used in accordance with the instruction
manual, may cause harmful interference to radio communications. Opera-
tion of this equipment in a residential area is likely to cause interference in
which case the user will be required to correct the interference at his or her
own expense.
Note: For connection to a listed direct plug-in power unit marked Class 2
and rated at +12 VDC regulated @ 40 mA maximum, –12 VDC regulated
@ 40 mA maximum, +5 VDC regulated @ 300 mA maximum.

1Plan Scanning System
Before installing the MS-3000 decoder you should sketch out a diagram of
your scanning system, showing equipment, connector and cable types, and
cable lengths.
Figure 1-1 shows a possible scanning system setup. There are six I/O con-
nectors on the MS-3000 decoder: the 25-pin host connector (see figure 1-9
on page 1-9), a 6--pin trigger connector (see figure 1-4 on page 1-5), the
5-pin power connector (see figure 1-7 on page 1-6), the modular RJ-45
scan head connector (see figure 1-5 on page 1-5), the modular RJ-11 LAN
connector (see figure 1-8 on page 1-7), and the 9-pin monitor connector
(see figure 1-11 on page 1-9).

maximum cable distances will
vary.

Chapter 1 Setup and Installation
1-4 MS-3000 Single Head Decoder User’s Manual
1–Setup and Inst.
Trigger Connector
The trigger connector (TRIG) is a 6-pin DIN socket (figure 1-3) that mates
with a 240 degree 6-pin DIN plug. Pin assignments are shown in table 1-2.
Pin 1 is the input from the object detector. When operating the decoder in
external trigger mode, a toggle at this pin causes the decoder to begin a
read cycle.
Pin 2 of the trigger connector is a programmable relay driver. The MS-3000
software can be programmed to set this pin high or low upon a good read, a
no read, a good match, or a mismatch. This pin can source or sink 4 mA
(maximum) and can be used to drive a small relay to operate an alarm,
diverter, etc.
Microscan offers an optical object detector (P/N 99-440001-03) that plugs
directly into this connector and a user-customized trigger port connector (P/
N 20-600090-02). 1
Figure 1-4 shows examples of positive and negative external trigger inputs
that could be applied to the trigger connector. (Shown in untriggered state.)

relays, etc.—which tend to be slow and bouncy and produce multiple trigger signals—are not
recommended unless equipped with optical sensors or filtered transitions (optical, Hall effect,
or DC solid state relays).

The power connector (figure 1-7) has a 5-pin DIN socket with pin assign-

You may also supply the required DC voltages yourself. A mating connector
(Switchcraft #05BL5M plug) is required.
Caution: Switching power supplies for Microscan equipment with a switching
noise of 20 mV or greater with ±12 VDC are not recommended due to exces-
sive ripple characteristics.

LAN Connector
The Local Area Network (LAN) connector allows the MS-3000 decoder to
communicate with a multidrop concentrator via a 4-wire cable (preferably
shielded) with a 6-pin, 6-wire, RJ-11 type connector. Pin assignments are as
shown in table 1-4. The LAN connector is used when a MS-3000 decoder is
configured for RS-485 multidrop communications.
For proper operation of RS-485 multidrop communications, the main cable
should not exceed 4000 feet, with each drop no more than 10 feet. The
Microscan MS-5000 multidrop concentrator can support up to 50 decoders
or other multidrop devices on one RS-485 line. Note that the last device
must be terminated correctly. RS-485 pinouts are also available at the host
connector.
Host Connector
The host connector (figure 1-9 on page 1-9), a 25-pin D-subminiature
socket, allows the decoder to be connected to a host, a concentrator, or
other communications device such as a PLC (programmable logic control-
ler), a monitor, a PC, a relay, a diverter, an alarm, etc.
Note:All Microscan products are configured as DTE at the host connector
when in RS-232 operation.
Caution: Do not use a host cable with more wires connected than are required
for the application. The host connector of the decoder has many outputs that
could cause damage or interfere with normal operation if connected and improp-
erly used.

A good read will cause a 5V signal (high or low) to be output to pin 6. A
noread will cause a 5V signal (high or low) to be output to pin 8.
Caution: There must be ±12V present before the decoder will transmit data to
the host. However, the decoder can receive commands without the presence
of either voltage.

the host port, pin 4 should not be wired as the results will be unpredictable.
