T&D’s RTR-500MBS-A Mobile Base Station is a GSM-based base unit for the T&D RTR-500 wireless monitoring system. These wireless dataloggers are ideal for monitoring and alarming temperature in trucks, warehouses and more. Like T&D’s other base units for this system, it requires an SMTP server that does not use SSL. Some cell companies advertise e-mail with their carrier services, but the RTR-500MBSA cannot use the automatic SIM settings provided by these cell services. With this in mind, CAS DataLoggers shows you how to quickly set up auto-data transfer in our latest Technical Article.
