The quikCONNECT ZEST UMTS (EU) is the latest in the Siretta range of cellular modems. It is the lowest cost modem in the range and is an ideal choice for entry level and seamless 3G/UMTS connectivity. It competes strongly on its robust and industrial specification using top cellular technology. The quikCONNECT ZEST 3G has a full 2.0 USB and an RS232 serial interface and can be wall or DIN rail mounted as required.


The quikCONNECT ZEST-N-UMTS (EU) is a dual band UMTS modem providing EU coverage, for the EMEA and APAC regions, on both UMTS and GPRS frequencies. In the absence of 3G signals if a lower data rate is all that is required then the quickConnect ZEST-N-GPRS(EU) is ideally suited.

Robust Connection Software:For seamless cellular connectioon that is controllable via SMS text, please see our linkCONNECT products.



Specification Overview:

Despite its highly competitive price, the quikCONNECT ZEST is built to the same exacting standards as the rest of the Siretta modem family. The quikCONNECT ZEST will be a popular choice for many situations requiring just UMTS/GPRS connectivity, and the flexible 6-21V power supply and a -40˚C to +85˚C operating temperature range allow the product to be used in most industrial applications.

Controlling the quikCONNECT ZEST:

The quikCONNECT ZEST is AT command driven as a standard modem but becomes a Smart modem with linkCONNECT software applied. 


The quikCONNECT ZEST enclosure can be either wall mounted or DIN rail mounted as standard, an unusual feature at this price point.


This capable low cost modem offers full nine pin functionality at the RS232 port and full USB 2.0 capability via the USB connector,  to cater for all application requirements. It will be at home in any of the following applications: automatic meter reading, remote vending machine management, LED signage, POS connectivity and many other situations requiring 3G connectivity in a reliable compact package measuring just 75 x 84 x 31mm.
