Preface
Welcome to the Ctek Z Series Cellular Router User’s Guide. This manual covers the Z4200 EVDO and the Z4400
UMTS/HSPA router. The User’s Guide will explain the basic operation of the router 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.
Note that all administrative functions and screens on the two models are identical with the exception of the Wireless
Status and Wireless Interface screens, and the Z4200's Activation screen which is replaced on the Z4400 by a SIM Tools
menu item.
1 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 are reduced to the absolute minimum necessary to register and make connections on a
network.
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 a relay power 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).

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 shipped from the
factory. To restore factory defaults, the unit must be running. You should wait a full two (2) minutes after booting or
powering on the unit before restoring factory defaults. After waiting two minutes press and continue to hold down the
Restore Defaults (inner) switch until the lights begin blinking (about 10 seconds). Release the DFLT switch as soon as the
lights begin to blink. The unit will restore its factory defaults and reboot itself. There is no need to restart or power cycle
the unit.

Figure 2 - DB9 Connector
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
RS-485 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 and JP2
should have jumpers center to left to use the auxiliary RS-485 serial port. Auxiliary serial port parameters (baud, parity,
etc.) are set using the RS232/485 configuration screen. From the factory the unit ships with the auxiliary RS-485 serial
port enabled and configured as a master device.
.
The J1 pin out configuration is as follows:
Terminal Block Pin JP1 & JP2 (internal) Center to Right JP1 & JP2 (internal) Center to Left
Pin 1 Din Src – Discrete Input Source
Pin 2 Din – Discrete Input (See Appendix A) TR- of RS-485 auxiliary serial port1

3 Start Up
Warning – You must connect antenna(s) to the SMA style antenna connectors on the router before turning it on.
Failure to do this could result in erratic start up behavior and could possibly damage the unit.
Note – Z Series routers ship from the factory with DHCP server enabled. The Default Gateway address for the
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 described 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. ON the Z4200 the antenna connector to the right of the LAN LED is the primary
(transmit/receive) antenna and the connector to the left of the reset button is the secondary or diversity antenna.
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
Figure 5 - Windows configuration
4 Administration, Configuration and Status
About Addressing – Devices connecting to cellular 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 Berkeley Internet Name Daemon (BIND) and Microsoft
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 allowed to reinitiate the request for

26 March 2013

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 any web browser pointed at http:// 192.168.1.10. A
login screen appears as shown below. The default User ID is “ctek” (without the quotes) and the default Password is also
“ctek”. Be sure to change the user ID and password and record your new selections.
Figure 6 - Login Screen
When you have completed the login process you will be presented with the top-level administration menu. Notice that the
SkyRouter’s firmware release level, input voltage level, and ambient temperature inside the case are displayed.

Figure 7 - Z4200 Top Menu
An optional top level menu is displayed if IPsec settings have previously been set to allow only secure traffic. Figure 9
shows this menu page which differs from the previous images in that it eliminates the button for the routing function.
Routing and port forwarding are not available in configurations where all of the IP traffic is being routed through an IPsec
tunnel.

Figure 9 - Z4200 Top Menu without Routing
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 wireless and Ethernet 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 always be used to apply any changes made on specific
Interface or Service screens.
4.2 Interfaces

4.2.1 The RS232/RS485 Interface
This screen sets basic parameters for the RS232 port and the auxiliary serial port. These settings should be made to
correspond to those on the far end of the serial connection or serial over IP emulation. The RS232 and RS485 serial ports
are available for all applications and can be connected to the TCP or UDB PAD feature. In addition the RS232 port can be
configured to establish a Point-To-Point Protocol (PPP) connection over a serial link.
Figure 14 - RS232/485 Configuration
Bit Rate – Selects transmit and receive speed. This setting is available on both the RS232 and RS485 ports.
Character Length – Selects the number of bits representing a character. This setting is available on both the RS232 and
RS485 ports.
Parity – Selects the parity bit setting that will match the far end. This setting is available on both the RS232 and RS485
ports.
Flow Control (DB9 Only) – Selects No flow control, Hardware Flow Control (RTS/CTS), or Software Flow Control
(XON/XOFF). If RTS/CTS is selected make sure that the cable you are using has those pins connected on both ends.
Many pre-manufactured cables either do not terminate these signals or else jumper them into a permanent True state.
