TheWA-NEXisaWirednetworkextenderconsistingoftwo isolated connection points. There are two main uses for the WA-NEX: Systemsthatexceedthemaximumcablelengthof3000m for radial Wired networks or 1500m for star Wired networks. The WA-NEX is used to partition the system, creating two smaller Wired networks as if it were a single system. Whentherearethreeormorecablesatasingleconnectionpointandtheuseofa RAK-STARis not possible. This is typical when retrofitting a 4-core system. For more information, see Appendix 1: WA-NEX 4 Core. NB Asystemwithapproximately two fully populated RAK-STAR units will be approaching the 3000mlimit in a typical installation. This can vary depending on the nature of the installation and the resulting routes taken by the cables. WA-NEX Manual Version 2.0.3

If both the Master and Remote sides have independent power, the power link can beremoved;if the remote side has no power source, the power link must be fitted. WA-NEX Manual Version 2.0.3

Terminating the WA-NEX There are two sets of termination jumpers on the WA-NEX,oneforeachhalfofthenewlypartitioned network. These must be terminated in the same fashion as any other Rako Wired device. As two Wired networks are being connected, the correct termination for each system is required. Terminated For end-of-line termination, use if the WA-NEX is connected to anything except a RAK-STAR. Star Terminated Usethis termination if the WA-NEX is connected to a RAK-STAR. Un-Terminated If the connection point is in the middle of a Wired network, remove the termination jumpers. Adding the WA-NEX as a device To address the WA-NEX, first connect to a HUB connected to the Master side. For full instructions on howtoconnecttoaHUB,seetheRasoftPro programming guides. WhentheHUBissuccessfully connected to Rasoft Pro, it should appear in the communications window with a green tick next to the HUB name. - Select “File” - “New Device” to open the “New Device Wizard.” - Select the WA-NEX from either the “Wired” or “All” device lists. - Give the device a suitable name and leave “Automatic ID” selected. - When prompted, press and hold the setup button on the WA-NEX. When the “A” status LEDbeginstoflash,release the setup button. WA-NEX Manual Version 2.0.3

OncetheWA-NEXhasbeenaddedasadevice,itwillappearinthedevicelist: NB Although it is not mandatory, it is advisable to set up the WA-NEX in order to access its diagnostic features in Rasoft Pro. Diagnostic features of the WA-NEX Each of the network diagnostic LEDs at the top of the PCB (A-F) gives information on the state of either side (Master and Remote) of the Wired network. A(Master In) Blue LED. Will flash whenever a command is received by the WA-NEX from the master side of the network. B(Master Error) RedLED.Willdisplay solid if no network can be found on the Master side of the WA-NEX. It will flash red if there is a network connected on the Master side but there is an error in communication (likely a cabling fault). WA-NEX Manual Version 2.0.3

C(RemoteIn) Blue LED. This LED will flash whenever a command is received by the WA-NEX from the remote side of the network. D(RemoteError) RedLED.Willdisplay solid if no network can be found on the Remote side of the WA-NEX. It will flash red if there is a network connected on the Remote side and if there is a communication error (likely a cabling fault). E(Master Out) Blue LED. This LED will flash whenever a command is transmitted by the WA-NEX to the Master side of the network. F(RemoteOut) Blue LED. This LED will flash whenever a command is transmitted by the WA-NEX to the Remotesideofthenetwork. Diagnostic features using Rasoft Pro Onceaddedtothesystem,theWA-NEXwillgivediagnosticfeedbackaboutthestateof the Rako Wired network: Pressing “Poll” will run a diagnostic check on both sides of the system. If there is a problem such as “Remote CAN Voltage Too Low” or “Short on Master Data Side," it will appear to the right of the screen in Rasoft Pro. In most cases, an advised course of action will also be given. WA-NEX Manual Version 2.0.3

If a system is too large, the WANEX can be implemented between RAK-STAR units to create two smaller systems. WA-NEX Manual Version 2.0.3
