INTRODUCTION
Metrologic’s HoloPlexer is a port and data concentrator used to simplify the installation of multiple
scanners. The HoloPlexer is available in two models: the MI8004 allows up to four scanners to be
connected to one host while the MI8008 allows up to eight scanners to be connected to one host.
Both models accommodate applications that require multiple scanning locations, but have only one
data input port available on the host device.
The HoloPlexer, and all of the scanners connected to it, operate as if it were a single scanner. Set up
and configuration commands sent to the HoloPlexer will program all of the scanners. Set up and
configuration is easily accomplished using an IBM compatible personal computer and either
MetroSet™ or HoloSet®.
The HoloPlexer provides a 38.4 kbps data transfer rate from the scanners while data transfer to the
host is programmable, supporting standard baud rates and handshaking up to 38.4 kbps using either
RS-232 or RS-422. Light emitting diode (LED) status indicators allow the user to easily monitor
HoloPlexer operation and input port activity.
The HoloPlexer also supports package detection (sensor input) and control (switched AC line output)
using Metrologic’s optional MX006 and MX001 interface accessories.

HOLOPLEXER STATUS INDICATORS
To enable the user to monitor HoloPlexer operation easily, different color status indicators (as
indicated on the previous page) are used. These functions are as follows:
The yellow TD/RD indicator (1) located to the left of the 25-pin output (host) connector indicates
communication activity through this connector. Any data to or received from the host system will
cause this indicator to flash.
The red indicators (4 or 8) located to the right of the power supply connector indicate input port
activity. These indicators light when a scanner has data to send to the HoloPlexer. (They monitor the
scanner’s RTS signal.) The numbering and position of the indicators correspond to the input port
connector location when looking directly at the rear panel of the HoloPlexer.
The green indicator (6) located to the right of the power switch indicates that the HoloPlexer is active
and what mode it is operating.

JUMPER SET UP
The HoloPlexer contains three internal jumpers, which will require set up if any of the following
features are to be used.
1. Host DTR Control (J7)
2. Use of MX006 (or other) Interface Accessory (J8)
3. RS-422 Host communications (J9) – May apply, see below.
If none of the above applies, the HoloPlexer is ready to use as received and will act as a 4 or 8 port,
RS-232 multiplexer. (The default locations of all jumpers are pins 1 and 2.)
If jumper set up is required, the top cover of the unit must be removed. This is accomplished using a
small, Phillips head screwdriver to remove the two screws on each side of the top cover. The top
cover is then slid back slightly to clear the rear connectors and lifted off exposing the printed circuit
board and its jumpers. DO NOT REMOVE THE FEET ON THE BOTTOM OF THE UNIT DURING
DISASSEMBLY.

1. Host DTR Control (J7):
Jumper J7 controls this option and is located on the left side of the circuit board behind the yellow
indicator. Move the jumper block from pins 1 and 2 to pins 2 and 3 to enable this option. The unit
must be configured for “host DTR enable” using the HoloSet® program as detailed later in this
manual.
IMPORTANT NOTE: When the host DTR option is enabled, port #8 of the MI8008 is unavailable
for use as a scanner/slave mux-box input.

JUMPER SET UP (CONTINUED)
2. Use of MX006 or Other Accessories (J8):
All accessories MUST be connected to the PORT-4/ACC connector of the HoloPlexer. Jumper J8
enables 5V power to the accessory port #4 and is located on the right side of the circuit board
behind the power switch. Move the jumper block from pins 1 and 2 to pins 2 and 3 to enable
power output.
3. RS-422 Host Communications (J9):
Normally, the RS-422 transmitter is under software control (currently unsupported). Jumper J9
enables the RS-422 transmitter output continuously and is located near the left side of the circuit
board behind the 25-pin output connector. Move the jumper block from pins 1 and 2 to pins 2 and
3 to enable the RS-422 transmitter continuously.
NOTE: If your circuit board does not contain jumper J9, contact Metrologic. You may also want to
contact Metrologic for information on a future software method of enabling the RS-422 transmitter.
After jumper set up is complete, reinstall the unit’s top cover.
CABLE CONNECTIONS AND CONNECTOR PIN OUTS
The cable connections are the same for a MI8004 and MI8008. There are two connectors on the front
of the box. The 4-pin white connector connects to the 5-volt power supply and the 25-pin D-sub
connector labeled “output” connects to the host. The 9-pin D-sub connectors on the back of the box
are input “ports” and are used as scanner or “slave” mux-box inputs. Additionally, any accessory,
such as Metrologic’s MX006, is always connected to the Port-4/ACC connector on the MI8004 or
MI8008.
Important RS-422 Connection Note:
If RS-422 host communications is NOT being utilized, do NOT connect any wiring to pins 9 and 10 of
the 25-pin D-sub host output connector. The use of a completely wired 25 pin RS-232
communications/extension cable is also not recommended for the same reason as if connects open
wiring to these two pins.

NOTE: RS-485 is user specific as to format and protocol and therefore requires custom software. It is
not supported by standard HoloPlexer software. Light pen emulation is currently not supported by
standard HoloPlexer software.
Cabling is straightforward. Use Metrologic cables #52702 (10 ft.), #52704 (20 ft.), or an equivalent for
scanner communication connections. These 25 to 9 pin cables are used to connect scanners to a
HoloPlexer or a “slave” HoloPlexer to a “master” HoloPlexer in a two layer/level system.
Host communication cables are available from Metrologic in a variety of configurations that meet many
common interface requirements or the user may fabricate his own cable using the host pin-out
information listed above. If a custom-made cable is used however, remember to leave pins 9 and 10
open unless RS-422 communications is being used.

SCANNER
The HoloPlexer and the scanners connected to it support most of the options found in either the
MetroSet or the HoloSet configuration program. When using HoloTrak scanners, configuring the
HoloPlexer causes the proper configuration to be sent through the HoloPlexer to the scanners. Many
scanner features for the scanners are specific to allowing communications to the HoloPlexer, and do
not interfere with the HoloPlexer’s ability to communicate to a host system. This is not true for other
scanners, which must be configured separately, using the appropriate configuration software (see
table on following page). Once all units are configured, the system will operate as a unified system.
Two Scanner Systems
If only two scanners are needed for a particular application and at least one of those scanners is a
HoloTrak, the scanners can be connected directly together without the need for a HoloPlexer. This
connection method is typically limited to two scanners only. Connecting more than two HoloTrak
scanners together (master-slave-slave) is not suggested as it will add appreciable propagation delay
to the application and may cause system problems.
HOLOPLEXER MOUNTING
The HoloPlexer can be easily mounted on a flat surface by using the optional HoloPlexer mounting kit
available from Metrologic. This kit consists of a mounting plate, which attaches to the bottom of the
HoloPlexer providing it with four user accessible screw mounting holes. The plate is secured to the
bottom of the unit using the six 32x7/16 flat head Phillips head screws provided.

SCANNER COMPATIBILITY
Metrologic scanners can be input to HoloPlexer. There are some limitations for scanners other than
HoloTrak as to the availability of all features.

GETTING STARTED
Make all the appropriate cable connections. Package detection/control output, host DTR and host RS422 require internal jumper changes and other considerations. Refer to the sections of this manual
detailing this information. When RS-422 communication is NOT being used, connect nothing to pins 9
& 10 of the HoloPlexer output (host) connector.
After all connections are made, power up the scanners and HoloPlexer(s). Notice that each scanner
takes several seconds to complete its power up sequence. As the motor comes up to speed, the
scanner’s green LED will flash and the lasers will remain off. Once the motor has come up to full
speed, the scanner will beep once, its red LED will come on steady, the green LED will stop flashing,
and all lasers will turn on.
The HoloPlexer/multiplexer box(es) takes little time to power up. Once the box has completed its
power up sequence, its green LED will start blinking at about a ½ second rate. This indicates that the
box is ready.
If you have not configured your application yet, run HoloSet program from your PC or laptop. (See
HoloSet manual for full configuration details.) In summary, after all units have powered up, the
scanners are ready to configure them. Enter program mode from HoloSet. Notice that the master box
goes into a rapid blink mode and all lasers on all scanners turn off. If this does not happen, check all
connections and the com port selection in HoloSet. Do not continue until this step works properly.
After entering the program mode in HoloSet, go to the configuration screen and choose the
appropriate settings. Hit F5 from this screen and the configuration will be downloaded to the system.
Once the master box receives the download, it will in turn try to configure each of its ports with the
configuration.
•
If a scanner is connected to a port, and it is receiving its download properly, it will beep and its
green LED with begin to blink.
•
If it does not, check the connection between the box and the scanner.
•
If a slave box is connected to the master box port, it will enter its rapid blink mode if it receiving its
download properly
•
If it does not, check the connection between the master and slave box.
After receiving its configuration, the slave box will download configuration information to the scanners
connected to it completing the cycle.

SUPPORTING PACKAGE DETECT/CONTROL OUTPUT
Additional hardware is necessary when package detection/control output is desired from the
HoloPlexer. Metrologic’s MX001 and MX006 provide this support. The MX001 provides for up to two
sensor inputs and can power these sensors if they are of the low (910-30V) DC type. It also provides
a switched AC line voltage output.
The MX006 provides the interface between the HoloPlexer (MI8004/8) and the MX001. In a two
layer/level (“master-slave”) system, this support is handled by the MASTER BOX ONLY. To establish
this support, connect the MX006’s 9 pin D-sub connector directly to the PORT-4/ACC connector of the
MASTER HoloPlexer box; the (lower) right hand port connector on the rear of the HoloPlexer. The
15-pin D-sub connector at the other end of the MX006 plugs into Metrologic cable #52708 or
equivalent. This cable is terminated by a military-style connector, which connects directly to the
MX001 Industrial Interface Box (see diagram below). As noted previously, jumper J8, inside the
(master) HoloPlexer (located behind the power switch) must be placed in position 2 and 3 to enable
the MX006. (See Jumper Set Up for full details on how to change this jumper.)
Lastly, the box needs to be configured correctly through either MetroSet or HoloSet to support
package detection and/or control output. (See Using the Package Detect/AC Output Menu in the
HoloSet documentation in this manual for full details of this set up.) If this option is not required, leave
jumper J8 in position 1 and 2 (default).
Any sensor used, must be set up to provide an output signal when the package is detected (commonly
the beam broken/dark on mode). The sensor is connected to the S IN terminals of the MX001. (In two
sensor systems, this sensor acts as the “entry” sensor.) The MX001 provides an indication of package
detection by lighting its S IN LED only when all cabling is complete. In addition, the HoloPlexer will also
provide the S IN indication by lighting its front panel, port #4 red LED. In two sensor systems, a second
sensor is connected to the A IN terminals of the MX001 and acts as the “exit” sensor. The MX001 will
also provide a package detect indication for this sensor by lighting its IN LED.
All cabling must be complete (MX001 connected to MX006) for this to happen. The HoloPlexer
however provides no LED indication of this second sensor’s operation.
10
SUPPORTING HOST DTR
The Host’s DTR RS-232 control signal can be used as a hardware communication flow control signal
controlling the HoloPlexer and allowing it to send data to the host only during those times that the host
provides the HoloPlexer with an active DTR signal. If this feature is required, connect the host DTR
signal to pin 20 of the HoloPlexer’s “output” connector and move jumper J7 (behind the yellow indicator)
to position 2 and 3. (See Jumper Set Up for full details on how to change this jumper.)
Lastly, the box needs to be configured correctly through MetroSet or HoloSet to support host DTR
control. (See Using RS-232 Format Menu in the HoloSet documentation in this manual for full details of
this set up.) If this option is not required, leave jumper J7 in position 1 and 2 (default).
IMPORTANT NOTE: When the host DTR option is enabled, port #8 of the MI8008 is unavailable for use
as a scanner/slave mux-box input.
BATTERY REPLACEMENT
The HoloPlexer contains a 3 volt, #2032 lithium battery (large button cell) used to provide backup
power to its memory and some other circuitry. This battery will last in excess of six years with the
HoloPlexer turned off and much longer with the HoloPlexer turned on. (Connecting power to the
HoloPlexer without turning the power switch on will not extend battery life.) If erratic HoloPlexer
operation is noted, the battery may require replacement. Lithium batteries #2032 are readily available
from all major battery manufacturers.
CAUTION:
Danger of explosion if battery is incorrectly replaced.
Replace only with the same or equivalent type recommended by the manufacture. Dispose of
the used batteries according to the manufacture’s instruction.
To replace the battery, remove the HoloPlexer case top cover. (See Jumper Set Up for full details on how
to change this jumper.) The battery is located in a holder behind the green indicator. Remove the old
battery from its holder and install the new one with its + terminal facing up. Then replace the case top
cover.
