System Overview
TMN-51T is a plug and play RS232 to GPRS gateway. It can easily retrofit a traditional
serial communication system to a more advance GPRS platform. Remote devices can be
centrally managed without upgrading the device firmware and central software. Unlike
those systems that the devices are centrally managed via PSTN or GSM dial up line or
lease line, TMN-51T can be a more cost economical solution to achieve an “always on”
data link network.
Note: TMN-51T may be able to use with 3G SIM card/data plan seamlessly but subjected
to Telco‟s offering.
Hence, our customers may enjoy the economical 3G data plan for higher data bandwidth
package.
