1.1. Copyright Notice
©2012 to 2013 Logic Data Systems LLC. All Rights Reserved.
This manual covers the operation of the Logic Data Systems L-5500 CDMA Cellular Modem.
Specifications described are typical only and are subject to normal manufacturing and
service tolerances.
Logic Data Systems LLC reserves the right to modify the equipment, its specifications or this
manual without prior notice, in the interest of improving performance, reliability, or
servicing. At the time of publication all data is correct for the operation of the equipment at
the voltage and/or temperature referred to. Performance data indicates typical values
related to the particular product.
No part of this documentation or information supplied may be divulged to any third party
without the express written consent of Logic Data Systems LLC.
Products offered may contain software which is proprietary to Logic Data Systems LLC or
partner companies. The offer or supply of these products and services does not include or
infer any transfer of ownership.
1.2. Modem Use
The Logic Data Systems L-5500 cellular modem is designed and intended for use in fixed,
nomadic, or mobile applications. “Fixed” assumes the device is physically secured at one
location and not easily moved to another location. “Mobile” assumes the modem is
physically secured in a vehicle and is operated when the vehicle is moving. “Nomadic”
assumes the modem is installed in a vehicle but is operated when the vehicle is stationary.
Please keep the cellular antenna of the L-5500 radio modem at a safe distance from your
head and body while the modem is in use (see below).
Caution: Maintain a distance of at least 20 cm (8 inches) between the transmitter antennas
and any person while in use. This modem is designed for use in applications that observe
the 20 cm separation distance.
1.3. Interference Issues
Avoid possible radio frequency (RF) interference by following these guidelines:
The use of cellular telephones or devices in aircraft is illegal. Use in aircraft may
endanger operation and disrupt the cellular network. Failure to observe this
restriction may result in suspension or denial of cellular services to the offender,
legal action or both.

Page 2
Do not operate in the vicinity of gasoline or diesel-fuel pumps unless use has been approved
and authorized.
Do not operate in locations where medical equipment that the device could interfere with
may be in use.
Do not operate in fuel depots, chemical plants, or blasting areas unless use has been
approved and authorized.
Use care if operating in the vicinity of protected personal medical devices, i.e., hearing aids
and pacemakers.
Operation in the presence of other electronic equipment may cause interference if
equipment is incorrectly protected. Follow recommendations for installation from equipment
manufacturers.
1.4. FCC Notification
This device complies with part 15 of the FCC rules. Operation is subject to the following
conditions: (1) This device may not cause harmful interference, and (2) this device must
accept any interference received, including interference that may cause undesired
operation.
Changes or modifications not expressly approved by the party responsible for compliance
could void the user's authority to operate the equipment.
Note: 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 in a residential installation. This
equipment generates, uses, and can radiate radio frequency energy and, if not installed and
used in accordance with the instructions, may cause harmful interference to radio
communications. However, there is no guarantee that interference will not occur in a
particular installation. If this equipment does cause harmful interference to radio or
television reception, which can be determined by turning the equipment off and on, the user
is encouraged to try to correct the interference by one or more of the following measures:
Reorient or relocate the receiving antenna.
Increase the separation between the equipment and receiver.
Connect the equipment into an outlet on a circuit different from that to which the
receiver is connected.
Consult the dealer or an experienced radio/TV technician for help.

The label contains the part number, serial number, MAC ID, FCC ID and the IMEI numbers
in both Hex and decimal format.
2.2. General Description
The L-5500 Modem from Logic Data Systems is the ideal solution for a wide range of
Internet Access, Corporate Network and wireless IP connectivity requirements.
The L-5500 product features high-speed wireless wide-area-network access to IP networks
over 3G cellular networks. The L-5500 cellular radio modem advanced router features full
Ethernet routing, DHCP Server, and NAT support. The embedded GPS makes it an ideal fit
for mobile applications requiring position information and Internet connectivity. The built-in
802.11 WiFi tether allows you to step away from your vehicle and remain connected at all
time. Alternatively, the client mode forwards all traffic via the WiFi interface instead of the
cellular interface.

2.4. External Interfaces
2.4.1. Front Panel Connections
Figure 1 - L-5500 radio modem's front panel
The L-5500 radio modem's front panel connections include:
GPS: SMA female, GPS antenna connector. This input requires a 3.3V, GPS antenna with an
SMA connection. For best coverage, use an active GPS antenna with a gain of >25dBm.
PWR: 9-28 VDC; the mating connector is a Molex 43025-0400 4 position connector.
LAN1 & LAN2: Input for standard or crossover Ethernet cable.
COM: Standard RS-232 port for debugging, Garmin FMI, and maintenance.
ANT: SMA female, primary antenna connection. See section “Antenna options” for more
information.
DIV: SMA female, receive diversity antenna. See section “Antenna options” for more
information.
WiFi: RP-SMA jack, WiFi antenna. See section “Antenna options” for more information.

2.5. RJ-45 Ethernet Ports
The L-5500 radio modem can accept either standard or cross over ethernet cables.
2.6. Power Cable Connections
If using the provided power cable to connect to a DC supply (car battery) use the following
diagrams and table to connect the unit.
Ensure the ignition sense line is connected to the vehicle's ignition. This line will initiate the
shutdown timer following ignition deactivation (if enabled).
Note: Both ignition sense and DC power are required to start up an L-5500.
Caution: Connect the red power wire to a CONSTANT hot source. To prevent corruption of
the L-5500 firmware, only use the ignition source to power off the unit.

2.7. Antenna Options
Antennas are available for L-5500 radio modems installations from Logic Data Systems.
2.7.1. Primary Cellular Antenna
The L-5500 product requires a multi-band cellular antenna for operation in the 800 MHz
band, the 1900 MHz band, and the 2100 MHz band. The primary antenna connection on the
L-5500 unit is an SMA female connector; therefore you must purchase an antenna with an
SMA male connector. Do not select an SMA antenna with “reverse polarity” or RP-Male.
Mounting options and cable lengths are the user’s choice and application specific.
Caution: To comply with FCC approval for this device, do not use a cellular antenna with a
gain greater than 5 dBi in the cellular (800MHz) band, or 4 dBi in the 1900MHz band.
2.7.2. RX Diversity Cellular Antenna
The L-5500 radio modem RX Diversity antenna has the same requirements as the primary
antenna with the exception of the connection. The RX Diversity antenna connection on the
L-5500 product is an SMA female connector; therefore an antenna with an SMA Male
connection is required. Mounting options and cable lengths are the user’s choice and
application specific. For best performance, separation between the Primary and Diversity
antenna should be at least 5/8 wavelength (=8 inches or 20 cm for 915 MHz).
Caution: To comply with FCC approval for this device, do not use a cellular antenna with a
gain greater than 5 dBi in the cellular (800MHz) band, or 4 dBi in the 1900MHz band.
2.7.3. GPS Antenna
The L-5500 radio modem’s GPS connector requires an external 3.3V GPS antenna. The GPS
antenna connection on the L-5500 product is a female SMA connector; therefore an antenna
with an SMA male connector is required. For best coverage, use an active antenna with a
gain >25dB. Mounting options and cable lengths are user’s choice and application specific.
2.7.4. WiFi Antenna
The WiFi antenna connection on the L-5500 product is an RP-SMA jack; therefore an
antenna with an RP-SMA plug is required. Mounting options and cable lengths are user’s
choice and application specific.
2.7.5. Antenna Spacing
Referring to Figure 4 for illustration, the L-5500 radio modem commonly uses four
separate antennas:
