The Lantronix LEO-I kit can be used with Local Managers equipped with an RS-232 module.
A valid and active SIM card is required for access to the Iridium satellite network. Contact your Service Provider if you do not have a SIM card.
The SIM card should be provisioned for Data. If you will be using SMS-initiated PPP, the SIM card will need to be provisioned for Voice as well.
An RS-232 module must be installed in the modem option slot of the Lantronix Local Manager as seen on the Lantronix 3200 model below.
Lantronix 500/5000/LM80/LM83X models have modem option slots on the front of the chassis and must have an RS-232 module installed.
Verify that the following items are included:
The connection between the ADU and BDU will require:
These cables can be run as a bundle between the mounting locations of the ADU and BDU. The cables terminating at the ADU should not have connectors, as they will not be able to pass through the ADU gaskets with RJ-45 connectors attached.
It is strongly recommended that each wire be properly marked for Iridium, GPS, power positive, and power negative. Incorrect Iridium/GPS wiring will prevent the unit from operating. Incorrect power wiring may damage the system.
The maximum wiring distance between the ADU and BDU is 500 ft (150 m).
Six RJ-45 plugs are included in the kit for use with the ADU - BDU cabling. If these plugs are missing or exhausted, be sure to use the correct plugs for your cable. Solid core Ethernet cables should use solid core terminals, while stranded core cables should use stranded core terminals. The included plugs are designed to work with both types of cables.
The connection between the BDU and Lantronix appliance will require:
To open the ADU, remove the four screws located at each corner of the lid.
Remove the cover to the SIM card compartment on the 9522B and install the SIM card. Ensure that the card is in the correct orientation.
If you will be using the included ADU Mounting Kit, attach the mounting brackets to the ADU now. The kit contains two U-bolts and a packet of mounting screws.
On some models, the mounting brackets will already be attached to the ADU.
To install the optional remote antenna kit, see Remote Antenna Kit.
Secure at least 1 of the corner screws before moving the ADU to its final location.
When closing the lid of the ADU, take care not to disturb the gasket that fits between the lid and the body of the chassis.
The ADU should be mounted within reach of the previously run cables. Other requirements:
Remove the corner screws of the ADU and open the lid.
Insert the power cable through the far-right gasket and route the wire to the power connector in the upper right-hand corner of the ADU. You will need a small screwdriver to connect the wires to the power module.
Leave the ADU open.
Thread the Iridium and GPS cables through their respective gaskets at the bottom of the ADU. Connect the cables to the PCB using the desired method. Ensure there are no tight bends in the cables by looping the cables inside the ADU. See the included photo for an example.
RJ-45: Dress each cable for standard straight-through configuration. Attach RJ-45 headers and connect to the Iridium and GPS ports on the PCB.
Terminal Blocks: Locate the green terminal blocks on the PCB. Consult the diagram included in this guide to identify the RS-422 9522B and GPS blocks. Each pin is labeled according to the 568-B wiring standard. Be sure to adjust for your wiring scheme if not using 568-B.
Strip the cable jacket of the CAT5 to the length of the terminal block. Strip individuals wires about a quarter inch. Insert wires into the terminal block, ensuring wire pairs remain twisted.
Replace the lid on the ADU and fasten each corner screw tightly.
When closing the lid of the ADU, take care not to disturb the gasket that fits between the lid and the body of the chassis.
If you are connecting the BDU to a Lantronix 3200 with an available expansion bay, you can remove the BDU from its standalone chassis and install it in an empty bay. Move the thumbscrews on the BDU from their default positions to the center holes to secure the BDU to the 3200 chassis. Newer model BDUs come equipped with a single rack ear that can be used to rack mount the BDU.
NOTE: The BDU cannot be installed in a Lantronix 5000 expansion bay.
The left side of the BDU (marked RS232) connects to the Lantronix appliance.
The right side of the BDU (marked RS422) connects to the Above Deck Unit (ADU).
Observe correct polarity when wiring power from the BDU to ADU. Incorrect wiring may cause severe damage to the ADU.
Use Ethernet cables to connect the Local RS-232 ports of the BDU to the Lantronix Local Manager.
BDU RS-232 LOCAL -- LEO-PA DB-9 ADAPTER ↔ UPLOGIX RS-232 MODULE - Use a straight-through Ethernet cable to connect the Local port of the BDU to the LEO-PA adapter. Plug the adapter into the RS-232 module on the Lantronix appliance.
Note that the LEO-PA adapter is REQUIRED for proper operation. If the LEO-PA adapter is missing, see the wiring diagram at the end of this document.
BDU RS-232 GPS -- UPLOGIX LOCAL MANAGER - Use a rolled (for example, a flat, blue Cisco console cable) Ethernet cable to connect the GPS port of the BDU to a free serial port on the Lantronix appliance.
A straight-through cable may be used with a Lantronix 3200 if the Local Manager serial port's null-modem setting is set to YES or AUTO. This connection is not required for proper operation of the LEO-I kit. However, a cable between the GPS ports on the BDU and ADU is still required.
Use the included power supply and power cord to connect the BDU's 24VDC power port to an electrical outlet. If power is configured correctly, the activity and traffic LEDs on the BDU will light up.
