802.11a/b/g, Fast Ethernet, 2.4/5 GHz, White/Black
Extend affordable and secure 802.11a/b/g wireless connectivity to multiple Ethernet devices — including cash registers, scales, time clocks and more. The CB3000 Client Bridge provides affordable and reliable wireless connectivity for Ethernet devices that do not have a PC or PCI card slot.
Connect everything from printers, scales and medical equipment, to manufacturing machinery, bar code readers, time clocks, cash registers and other data collection devices via an RJ-45 port. This cost-efficient connection point can support up to 16 wireless clients via an Ethernet hub. And advanced security capabilities protect your traffic from being deciphered and your network from unauthorized access.
POS Protocol Support: RPL, PXE; Limit one RPL or PXE terminal per bridge.

<b>Business challenge</b>
You need to connect your cash registers to your network, but the need to move the registers throughout the year to accommodate seasonal needs will result in high wiring costs.
<b>Solution</b>
Quickly and easily extend cost-effective wireless connectivity for up to 16 cash registers with a single CB3000. And when you need to move your registers to better serve holiday buyers, or for an improved floor plan, just simply relocate the CB3000 with the devices to maintain wireless connectivity - without incurring the expense and time of wiring and re-wiring.
<b>Business challenge</b>
You have an application that will deliver competitive advantage, but it requires the capture real time data from some of your larger equipment. Since the equipment does not have a PC or PCI card slot, you cannot establish the wireless connectivity you need.
<b>Solution</b>
The CB3000 extends wireless connectivity to equipment that typically would not be able to establish a wireless connection via the RJ-45 port. Ideal for connecting printers, scales, time clocks, point-of-sale and more to your wireless network.
