Industrial 3G RS232/485/TTL Serial Modem

The WLINK WL-D803 is a 3G Modem series designed to emulate serial connections for RS232 devices, and can be used with a variety of existing serial devices to turn them into M2M/IoT solutions. This typically includes things like water flow monitoring/control, meter reading, traffic monitoring/control, digital sign control, etc.

The unit converts RS232 data signals into IP packets for point-to-point communications with an endpoint. The endpoint can be an Ethernet enabled device, or a device behind another WLINK unit.

We also have a TTL or RS485 supporting version of this hardware on request.

This unit is designed for use on the Spark UMTS network.
