Preface
Welcome to the Ctek Z4300 Router User’s Guide. The Z4300 is an EDGE model with GPRS fallback. The configuration
and administration of the 4300 model is identical to previous generations of SkyRouters with the exception of a few small
differences noted in the text. The User’s Guide will explain the basic operation of the routers and take you through the
necessary settings to get your wireless application online. Additional information and applicable technical notices can be
found at www.ctekproducts.com

1 Introduction
Wireless routers provide application and network designers with a bridge between the world of IT infrastructure and the
evolving wireless data 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 are reduced to the absolute minimum necessary to register and make connections on a network.
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 GSM EDGE wireless networks. A fallback GPRS transport is also provided. 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 EDGE/PRS transport.

2 Connectors, Lights, Switches, and Jumpers
2.1 Switches
Referring to Figure 1, there are two switches on the front of the Z Series router. S1 (Reset) causes a hard reset of unit.
S2 (DFLT) is used to completely restore the firmware settings that were included when the product was shi pped from the
factory. To restore factory defaults, the unit must be running. Press the Restore Defaults (inner) switch and hold it down
for 10 seconds. After 10 seconds, you will see both the green and yellow lights go off. At that time you may either press
the reset (outer) switch or cycle power on the unit.

The network status indicators LINK and SVC are interpreted as follows:
SVC – Multi-color (yellow/green). Indicates:
a) Power

2.3 Connectors
RS232 Connector
The RS232 connector pin out diagram is shown below.
– This connector is a standard RS232 DCE interface. A straight-through RS232 cable sho uld be used.
Figure 2
Ethernet Connector
The Ethernet connector on the Z Series is a standard RJ45 connector with auto polarity sensing and can be used with
either a standard Ethernet cable or a reverse (cross over) Ethernet cable.
Terminal Block
Connector J1 supports four separate functions, power, relay contact closure detection, relay driver output, and auxiliary
serial port serial data. Contact closure pins 2 and 4 are shared with the auxiliary serial port. To option remove the circuit
board and locate 3-pin headers JP1 & JP2 behind the green connector. Facing the end of the board containing the green
connector JP1 and JP2 should have jumpers center to right to use the discrete I/O (Din, Dout), and JP1 a nd JP2 should
have jumpers center to left to use the auxiliary serial port. Auxiliary serial port parameters (baud, parity, etc.) are set using
the RS232 screen. From the factory the unit ships with the auxiliary serial port enabled.

The pin out configuration is as follows:

3 Start Up
Warning
Failure to do this could result in erratic start up behavior and could possibly damage the unit.
Note
unit is 192.168.1.10. The address of the web based administration is also 192.168.1.10. After you have activated
your unit on the wireless network it WILL NOT have a DNS address, meaning that public Internet web access will
not work. To load DNS values go to the Ethernet Interface screen, select “Acquire From Wireless Network” and
press the update button. At this point the Primary and Secondary DNS addresses in the Ethernet Interface screen
will be populated with the DNS addresses provided by your wireless network. As a last step restart both the
router and the connected PC.

3.1 Power
Before starting connect the supplied 12VDC power adapter to the power connector de scribed in Section 2. The adapter
supplied with your router is suitable for use with 120VAC 60-hertz wall power. If you need a different power solutions
contact Ctek.
3.2 Connecting the Antenna
Antennas should be attached to the SMA style antenna connectors described in section 3. The antenna must be
connected before powering the unit on.
3.3 Connecting to the Ethernet Port – Administrative Connection
For a direct Ethernet connection between a PC connect to the Ethernet port using a standard or reverse Ethernet cable.
For initial configuration and administration with a PC or workstation Ctek recommends that the PC be set to obtain an IP
address and obtain a DNS address automatically. For Windows PCs make the following settings under the networking
control panel

4 Administration, Configuration and Status
About Addressing – Devices connecting to GSM/EDGE/GPRS networks are assigned an IP address by the serving
network. Address assignment may either be static or the unit will be dynamically assigned an IP address, depending on
arrangements that you have made with your wireless network operator. Dynamically assigned IP address remain in effect
for a period of time assigned by the network operator, usually at most a small number of hours.
Ctek’s Z Series includes features that manage the temporal nature of dynamically assigned wireless IP addresses. Using
the Wireless Configuration screen you can configure your router to use a Dynamic DNS (DDNS) service. Ctek operates a
DDNS test bed that allows our customers to observe the performance and reliability of DDNS with their applications. For
large-scale commercial applications Ctek recommends that users configure their own DDNS, managed and maintained
with the customers ongoing IT operations. The Z Series may also be configured to operate with a standard DNS having
Dynamic DNS capabilities. Examples of this type of service would be
Server 2000 and up.
For detailed information see Ctek’s TechNote S001.

Even if you elect to use a static IP address a DDNS service will add value in two ways. First, when the networks static
addressing assignment fails there is a mandatory waiting period before the endpoint is allowe d to reinitiate the request for
a static address registration. During this period of time the network will dynamically assign addresses to the end point. A
DDNS service will make the end point network addressable (by name) during this period of time. Secondly, a name
service allows your end point to be known by a name that is independent of network addressing. Addressing a unit by
name may be easier for end users to remember and will, over a long period of time, reduce maintenance problems.
4.1 Getting Started
Once the PC has been set up properly and physically connected to the router you are ready to begin configuring the
router for your application. To access the Administration menu use a conventional web browser pointed at http://
192.168.1.10. A login screen appears as shown below. The default User ID is “ctek” (without the quote s) a nd the default
Password is also “ctek”. Be sure to change the user ID and password and record your new selections.
Figure 6
When you have completed the login process you will be presented with the top-level administration menu.

Figure 7
Note that the administration menu is divided into four sections. The Interfaces section deals with physical connectivity,
managing the connection and subtended devices. Status screens are provided for the EGPRS/GPRS and Ethern et
interfaces. Services are applications that are within the router core to modify the behavior of a specific interface or to
change system wide parameters within the router core. Under the Options category users can find any optional or custom
applications and tools provided to maintain the router.
Important Note – The Restart button must be used to apply any changes made on specific Interface
or Service screens.
4.2 Interfaces
4.2.1 Configuring The Wireless Interface
The configuration screen for the wireless interface is shown below. The actual wireless interface is provisioned and
configured by the wireless Network Operator. The router’s Wireless Interface Configuration screen is used to establish
select from those capabilities available such as inactivity timeouts and Name Server selections.
