RS232 / RS485 3G gateway Industrial Modem DTU With Sim Card Slot

 
RS232 / RS485 3G gateway Industrial Modem DTU With Sim Card Slot
 
Description
 
The WL-D805 3G gateway can look similar to the common Modems / terminals. The cellular gateway  has additional processing capability and built-in software which allows them to operate autonomously as self-managing communications devices.
Once configured, WLINK Gateways provide ‘IP’ or internet communications for other devices which have limited or no built-in capability to manage a modem.
All of our Gateways can act as an IP server or an IP client, meaning they can either make or accept IP connections & provide a transparent data link between the connected device back to your server or PC.
Gateways are approved to various government and/or network so no further testing or certification is required. This combined with only minimal configuration and testing requirements means a very fast time-to-market.
