Plan 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).

Front Panel Connectors
The MS-3000 decoder has six I/O connectors. On the front panel
(figure 1-2) there are the following two connectors:
a. Trigger (Micr oscan or other object detector) (6-pin DIN socket)
b. Scan head (modular RJ-45)
Figure 1-2 Front Panel
Under ideal conditions, maximum cable lengths can match
the distances shown in table
1-1
. However, since cable
lengths and sizes are dictat ed
by local conditions such as
wire size, wire shape (flat or
round), shielding, grounding,
extraneous signal noise, etc.,
maximum cable distanc es will
vary.

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).

LAN Connector
The Local Area Network ( LA N) co nnector allows the MS-300 0 de co de r to
communicate with a mu lt idr op conc en tr ato r via a 4-w ire cabl e (p r efer a bl y
shielded) with a 6 -pin, 6-wir e, RJ- 11 type c onnec tor. Pin ass ignme nts a re 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 controller), 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 improperly 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.

Configure Decoder
Settings for Communications, Operations, Code Types, and User Outputs
and Raster Setup are stored in non-volatile memory and can be configured
by menu, serial command, or profile card commands.
For explanations of configuration settings, see Chapter 2, “Menu Configu-
ration.”
To establish communications you will need to match the host’s or auxiliary
terminal’s communication settings with your decoder’s settings (see Com-
munications Menu” on page 2-5). Also make certain that the code type
enabled in the decoder matches that of the label being used (see Code
Types Menu” on page 2-22).
Hint: Sending the <P> command will allow your scan head to read all of the
listed code types.
4
Position Scan Head and Label
Before testing, you will need to position the scan head and label in a manner that matches as nearly as possible the actual conditions of your application. Consult your scan head user’s manual for important setup
specifications.
Communicating with an d ASCII Terminal
The MS-3000 decoder communicates in full duplex, terminal mode with no
handshake. It also recognizes carriage returns and line feeds.
The host or ASCII terminal must match the following de fault settin gs before an y
communication can ta ke plac e:
9600
Baud Rate,
Seven
Data Bits,
Even
Parity,
and
One
Stop Bit.
A PC or Macintosh computer can be used as a dumb terminal if connected as
shown in table 1-5 on page 1-8 and running a communications program set to
the above defaults. See your computer user’s manual for communication’s port
pinouts.

This test calculates the percentage of scans decoded. It is useful during
setup procedures to help optimize scan head-to-label orientation.
a. Place the label used i n your application i n front of the scan hea d and
within the desired read range.
Note:
Ensure that the label being scanned is of a code type enabled in the
decoder’s software.
Hint:
Read rates are easier to read on the screen if Postamble is enabled.
b. Select from the ESP Utilities menu or send a <C> command to the
decoder to start testing (see the “Enter Read Rate Test” command on
page 5-5).
A percentage number from 0 to 100
will be displayed on the monitor in
the read rate test indicating the ratio
of good reads per total number of
scans.
c. Find the correct read rate area by
moving the label in and out and right
and left while observing read rate on
the monitor.
Avoid the specular reflection area (see scan head user’s manual).
d. Record the range area measurements and file the test results for
future reference.
If the results are not satisfactory, reposition or re-configure the
decoder or choose a different narrow-bar-width label size.
e. Select from the ESP Utilities menu or send a <J> command to the
decoder when testing is complete (see the “Exit Read Rate Test” command on page 5-5).

Install Decoder
The MS-3000 decoder can be mounted temporarily using the four rubber
pads, or permanently, as follows:
a. Position the decoder in a dry place.
b. Before mounting, ensure that there is at least a 3 inch (76.2 mm) clear-
ance at the rear and front of the decoder for the connectors and cables
being used.
c. Use the measurements provided in figure 1-12 to locate centers of
mounting holes and drill four 5/32 inch or four 4 mm holes.
d. Secure decoder with four 6-32 screws of the appropriate length.
Caution: Make certain that mounting screws do not penetrate into the
decoder case more than .175 in. (4.4 mm) or damage to the decoder could
result.

Ground and Shield Considerations
Proper grounding is necessary for operator safety, noise reduction, and the
protection of equipment from voltage transients. Buildings–including any
steelwork, all circuits, and all junction boxes–must be grounded directly to
an earth ground in compliance with local and national electrical codes.
RS-232 signals have a common signal ground (pin 7 of the 25-pin connector). Pin 7 is normally connected to pin 1 (chassis ground) in the decoder;
however, under certain conditions (e.g., when potential differences exist
between power outlet grounds) signal and chassis grounds can be isolated
from each other inside the decoder by Microscan technicians.
Any data line, as necessary, can be shielded. If shielding is used, isolate it
from the decoder and ground only to the host earth ground.
Noise Interference
Noise interference can be mini-
mized if cabling subject to
noise interference is twisted
and/or shielded or encased in
grounded conduit, and the
conduit or shielding (“drain”
line) is grounded only to earth
ground at the host, as shown in
figure 1-14. You might need to
examine and if necessa ry cut
the shielding connec ti on at or
near the concentrator cable
connector.
Ground Loops
Ground loops, signal degradation due to different ground potentials in com-
municating devices, can be eliminated or minimized by ensuring that the
host, concentrator, and their power supplies are connected to a common
earth ground.

This chapter describes how to configure the MS-3000 decoder with on
screen menu commands from a host or auxiliary terminal.
All keystrokes are in bold typeface.
Default parameters in the menu structures are also in bold typeface.
All of these parameters, with the exception of Full Screens, can also be
changed by serial commands (see Chapter 3, “Serial Configuration”).
In addition, most of these configuration parameters can also be changed
with a Microscan profile card (P/N 99-500011-01), obtainable from your
Microscan representative (see Chapter 4, “Profile Card Configuration”).
Communicating with an ASCII Terminal
The MS-3000 decoder communicates in full duplex, terminal mode with no
handshake. It also recognizes carriage returns and line feeds.
The host or ASCII terminal with must match the following default settings
before any communication can take place: 9600 Baud Rate, Seven Data
Bits
, Even
Parity, and
One
Stop Bit.

Press N to exit without saving changes, or press Y to retain the current settings to non-volatile RAM for power up. If Y is selected, a beep will indicate
the save has been carried out.
Loss of Communications
Defaulting might be necessary if communications between the decoder and
another device are interrupted or if using incompatible equipment (for
example, a terminal is set to communicate at 9600 baud, but the decoder is
configured at 38.4K baud). Communication can also be lost if an address
has been assigned to the decoder.
To reset parameters to default values, see Appendix C, “Defaulting the
Decoder,” on page A-4.
Defining Special Characters
To define any control character from the ASCII table: Press SP once, then
enter the control character by holding down the control key and simultaneously pressing the desired character. For example to define a line feed,
press SP, then Control and J simultaneously. It is displayed as ^J on the
command line and as <LF> in the menu when the screen is refreshed.
To define CR as a character: Press SP, then CR. It is displayed as ^M on
the command line and as <CR> in the menu when the screen is refreshed.
To define a space as a character: Press SP twice. It is displayed as a blank
space in the menu when the screen is refreshed. While it appears that nothing has been assigned, the hex value 20 will be sent during data transmission.
To select NUL as t he char act er: Press SP, then a 0 (zero). It is displayed as
<NUL> in the menu when the screen is refreshed.
