Introduction
Wireless routers provide application and network designers with a bridge between the world of IT infrastructure and the
evolving wireless M2M networks. With the Z Series the wireless transport is fully integrated into the product’s routing
fabric meaning that you can approach the setup and operation of this product much as with any other IP addressable
device. Wireless considerations have been reduced to the absolute minimum necessary to register and make connections
on a network.
The Z Series is also a powerful application platform. Ctek offers an Automation Control, an Irrigation Control, and a
Navigation (LBS) application package that is fully integrated with the SkyRouter operating environment. Ctek also offers a
full range of development tools for customers choosing to develop their own applications.
A number of optional controllers are available for use with the models covered in this manual including a micro-amp
standby power controller, an analog/digital I/O controller, and an analog output controller. The operation of these devices
is covered in their specific user manual and in applicable TechNotes.
1.1
Theory of Operation
The Z Series router is a complete IP router that routes traffic over LAN Ethernet (10/100baseT) connections. The wireless
features of the router simply extend the IP routing capabilities to include routing and network address translation (NAT)
over cellular wireless networks. As with most routers Ctek’s Z Series can be viewed as having a Local Area Network
(LAN) side and a Wide Area Network (WAN) side. Traffic originating at the router’s Ethernet or Serial port is considered
LAN traffic. The Wide Area Network connection is over the wireless network’s bearer channel(s).
