The SMS Bridge provides an economical means of transmitting reefer monitoring
data to the YORK Global Monitoring Server (GMS). Instead of sending SMS
messages directly to the GMS server in Denmark, your monitoring systems send
them to the SMS Bridge. The SMS Bridge relays the messages to the GMS server
via the Internet, reducing the cost of data transmission.
The SMS Bridge is intended for use with the YORK RefLine and RefBox reefer
monitoring systems. It consists of a GSM modem and a software application for a
Windows 2000 or XP PC.

serial port adaptor.
The SMS Bridge receives data over the GSM mobile phone network via SMS text
messages. This requires a GSM account and SIM card (not included).
