How to Connect a Cellular Modem to Your Accsense Pod

For A2-05 Ethernet Loggers and Wireless Pods via B1-06 Gateways


Accsense monitoring pods use an Internet connection to monitor a wide range of physical values including Temperature, Humidity, Current/Voltage and more. However if you don't have access to Ethernet, and you still need Accsense alarm capabilities, you can connect a cellular modem to your Accsense system. This gives you a simple and quick way to bring your Ethernet-wired or Wireless pod online. The Applications Specialists at CAS DataLoggers have written up this short 3-Step tutorial to keep you connected to your critical data!

Connecting Your Modem:

1.  Your choice of modem depends largely on which cellular carrier you choose. In North America there are 2 cellular technologies: GSM and CDMA. In the United States, ATT and T-Mobile are the main large companies using GSM technologies, while Sprint and Verizon are 2 big CDMA carriers. There are also many smaller carriers available to select from. Always ask what technology your carrier uses if you are going to go with a smaller carrier or a prepaid system (if the carrier uses a SIM card, it's generally a GSM carrier).

2.  Once you've chosen a particular cellular technology, you'll need to find a modem that has an Ethernet connection on it and which provides a DHCP connection for the Accsense B1-06 gateway or the A2-05 standalone wired pod. You'll also need to check to see if Port 443 needs to be opened in the modem's firewall.

3.  Since the Accsense system's interface is all contained in the managed webpage at, you're nearly finished after you get the modem properly set up and connected to the cellular network. Note: you can also go to and click ‘Customer Login' at the top menu. Simply power up the Accsense B1-06 or A2-05 and plug in the Ethernet cable, and then the pod will begin logging data and monitoring for alarms.

A2-05 Power Over Ethernet Logger

The A2-05 Ethernet Temperature monitor is designed for temperature measurement and alarm in medical refrigerators, freezers, cryogenic storage and incubators. The data logger has connections for external RTD and Thermocouple sensors. In the event of a loss of the network connection, the datalogger will store up to 256 data points, or until the connection is restored.

World-Class Medical Monitoring:

Accsense medical monitoring systems are the choice of many distinguished medical and academic institutions including Stanford Hospital and Clinics, the Smithsonian Institute, the Cleveland Clinic Foundation, New York Hospital Queens, and the US Navy Medical Center, among many others.
