LOGIC NET INSTALLATION GUIDE
The LM3000 Series control units consist of 6 different models:
LM3000, LM3000E, LM3008, LM3008E, LM3016 and LM3016E.The
LM3000 Series control units come in two interface configurations,
serial interface only and ethernet and serial interface. The
LM3008/LM3008E includes 8 LED’s to show the status of up to 8
kitchen systems. The LM3016/LM3016E includes 16 LED’s to show
the status of up to 16 kitchen systems.

Installation of the LM3000 Series is covered in 5a, while installation of
the LM3000E Series is covered in 5b.
1. Planning System Configurations
The proper configuration for Logic Net is a loop. Total RS485
cable length is not to exceed 1220 m (4000 ft.). CAT5 cables should
be used.
The loop configuration provides redundancy and is, therefore, more
reliable. A loop configuration starts with an LM3000, which then has
an LS3000 attached to it. Another LS3000 is attached to the previous
LS3000, and so on, ending with the last LS3000 attaching back to the
LM3000.
A break in a cable between any two devices would break the loop, but
communication would still be possible between the LM3000 and all
LS3000s. This is possible because both RS485 ports on the LM3000
communicate information from the host at the same time.
Note: Simple chain configurations starting from each RS485 port
on the LM3000 is not recommended. The connections must
be in a loop form.
Sample Loop Configuration

2. Mounting LS3000 & LM3000 Units
Mounting brackets are provided to facilitate mounting the LS3000 &
LM3000 to a wall. The installer should ensure that the wall anchors
used with the mounting brackets have the capacity to support 4.3 kg
(9.5 lb.). This weight is determined by adding a safety margin weight
to the weight of the unit. Wall anchors that specify weight capacity are
available commercially.
3. LS3000 Installation & Setup
Make sure that power for all equipment is off before making
connections. Making connections while power is on may cause
damages. A keyboard/bump bar is required for LS3000 setup. After
system component placement and cabling, set up each LS3000 using
the following procedure:
1 Attach the monitor, keyboard/bumpbar, power supply, and
optional RS232 device to the LS3000.
2 Plug in the monitor and the LS3000 power supply to an AC
power source with surge protection and switch ON the monitor.
3 Reset the LS3000 by pressing the reset button at the front panel
with a pointed device.
4 After pressing RESET, within 5 seconds, press up or down arrow
on the keyboard/bumpbar to navigate the setup menu.
5 Verify that the values in the banner message box at the top of the
screen for RAM Test and E2PROM Status are OK. If the values
are other than OK, repeat step 3 and 4. If this fails to resolve the
problem, replace the unit.
6 Logic Station address setup
a. Select Address Setup from the menu using up or down arrow
keys. Press ENTER to open the input area.
b. Enter the assigned unique, 2-digit Logic Station address in
the range between 00 and 15.
c. Press ENTER to accept.
d. Verify that the address you entered appears at the top left in
the banner message box.
7 Press CTRL to exit the LS3000 setup menu.
8 You have now completed the setup for one LS3000. Repeat as
necessary for each LS3000 in the system, ensuring a unique
address for each LS3000. Always verify your input in the banner
message box at the top of the panel.
4. LS3000 Diagnostic Program
Each time the LS3000 is powered on, it runs a ROM-based setup and
diagnostic program that is used to set system parameters and provide
problem determination information. You can run the program by
pressing the system RESET button. As soon as the diagnostic menu
appears, quickly press the up arrow or the down arrow keys on the
keyboard to highlight the required function. Press ENTER to select
the function. After the setting or test is complete, exit by pressing
CTRL key.
5a. LM3000 Installation & Setup
Make sure that power for all equipment is off before making
connections. Making connections while power is on may cause
damages.
1 Attach the LM3000 to an enabled RS232 port on the host server
with RS232 cable.
2 The LM3000 is then connected to the network of LS3000 I/O
units via RS485 cable loop. The connections must be in a loop
form with Cat 5 cables. (See Figure 1)
3 Attach the power supply to the LM3000. Plug the power supply
into an AC power source with surge protection. A lit LED on the
front of the LM3000 indicates that power is ON.

4 Reset the LM3000 (using pointed device to press the RESET
button at the front panel). The LM3000 should now recognize the
attached LS3000s. The banner message box on the top of all
the LS3000 monitors should show Control Status as Present.
5b. LM3000E Series Installation & IP Setup
Make sure that power for all equipment is off before making
connections. Making connections while power is on may cause
damage.
1 The LM3000E Ethernet port has to be connected to the server
computer via an Ethernet hub.
2 The LM3000E is then connected to the network of LS3000 I/O
units via RS485 cable loop. The connections must be in a loop
form with Cat 5 cables. (See Figure 2)
3 Connect at least one I/O unit (with VGA display connected) to the
LM3000E and connect the LM3000E/LM3008E to the Ethernet
LAN (as shown in Figure 2). Power on the I/O unit. At power on
of LM3000E, the current IP address and port number are shown
on the I/O unit VGA display.
4 Record the original PC IP address. Then set the computer’s IP
address to same IP group (that is, the first 3 octet numbers has
to match exactly) as the LM3000E current IP shown on the
LS3000 VGA screen. Refer to the procedures outlined in the
operating systems’ manual for setting the computer’s IP address.
5 Run Telnet program on the server PC with connection to LAN.
(For Windows, under command prompt, enter “Telnet <IP
address>” where <IP address> is the current IP of the LM3000E
displayed on the LS3000VGA screen). Figure 2
Note: Simple chain configurations starting from each RS485
port on the LM3000E is not recommended. The
connections must be in a loop form.
6 Enter command “1” with new IP address as parameter to enter
new IP address for the unit. For example, enter “1
192.168.100.10” to change IP to “192.168.100.10”. (Note: set IP
address to same original IP group in your network. You may
need to check with network administrator for a free IP address). 6. LEDs on Front Panel (LM3008,
LM3008E, LM3016, LM3016E only)
The 8 LEDs on front panel of LM3008E indicates status of I/O
units from address 0 to 7. If more than 8 stations are needed,
model LM3016E is available with 16 LEDs. When the LED is off,
the corresponding I/O unit is off-line. When the LED is on or
blinking, the corresponding I/O unit is on-line. Check the I/O unit
connections if any active LS3000 is not shown with correct LED
status. One or more LEDs blinking indicates a cable break or
loose connection. While the system still works with all on-line
stations under this single cable fault condition, the blinking
LEDs alert you to a cable connection failure that has to be
remedied. The location of the cable break can be easily
identified. The group of blinking LEDs shows that this segment of
network is disconnected from the rest of the network segment with
steadily ON LEDs.
7 Check that the “Current Configuration” shows the required IP
address. If necessary, change IP again with command “1”. Then,
enter command “4” to save settings. To cancel the IP changes
made in this session, enter command “0” to quit without save.
8 Set the server PC back to original network IP address recorded
down in step 2.
After IP address has been changed, the LM3000E will run with the
new IP address automatically. The new IP address will be shown on
the I/O unit VGA display.
Remark:
If Telnet shows double characters when typing in commands &
parameters, it’s due to local echo being set to on. To eliminate the
double characters, set local echo to off. (Enter “Telnet” in command
prompt to start Telnet and enter command “unset local_echo” for
Windows 2000 or “unset localecho” for Windows XP. Enter “quit”
to exit Telnet.)
