RX55 Quick Start Guide
One year of AirLink Complete is included with your router when you or your Sierra Wireless Partner register your router with ALMS. Registering with ALMS
allows you to remotely deploy, monitor and maintain multiple AirLink routers and to access technical support.
For more information on AirLink Complete and ALMS, see the included AirLink Complete guide. Note that your Sierra Wireless Partner may have pre-registered the
router and activated your AirLink Complete subscription. Your router will automatically connect to ALMS the first time it powers on to complete its registration.
STEP 1: Register Your Router with ALMS
Reset
1. Using a #1 Phillips screwdriver, remove the SIM card cover.
2. Slide the SIM cards into the SIM card slots until they click into place. By default, the SIM card
in slot 1 (the upper slot) is the Primary SIM card. When the RX55 is powered on or reboots, it
automatically connects to the network associated with the Primary SIM card.
3. Re-attach the cover.
STEP 2: Install Your SIM Cards

4. Connect a Windows® computer to the router with an Ethernet cable. If required
by your application, connect the RS-232 port and / or the USB port.
3. Connect 9 – 36 VDC.
To operate the router between 7 – 36 V,
after startup, adjust the Voltage Threshold
(see the AirLink OS documentation).

Sierra Wireless strongly recommends that you always ground the chassis using the unpainted mounting hole. For more information, refer to the RX55
Hardware User Guide. A green LED chase may occur when the router is powered on, indicating that the radio module is being configured for your SIM card. The
process can take 6–7 minutes. Once the router’s radio module is configured for the SIM card, it automatically begins the activation/provisioning process and
attempts to connect to the mobile network. This process takes a few minutes. A successful connection is indicated by a green Cellular LED. If the router does not
automatically connect to the network, refer to the AirLink OS documentation at source.sierrawireless.com/airlinkos.
