The RAK-LINK is an essential component of any Rako Wired network. The purpose of the RAK-LINK is to provide power to the Wired network and communicate between the Wired network and the RAK8-MB units. Up to 32 circuits can be mapped to a single RAK-LINK (4 RAK8-MB units); multiple RAK-LINKs may be used should more circuits be required. The RAK-LINK supports up to two CAT5 or CAT6 cables via the punch-down connector and has three RJ11 ports that can connect Rako Wired accessories. The power supply on the RAK-LINK is capable of powering up to 40 Rako Wired devices via the connections to the punch-down connector. NB The RJ11 ports are not suitable for connecting multiple devices and must be used solely for single Rako Wired accessories. For a specific calculation of power requirements, please refer to the RAK-LINK diagnostics application sheet. RAK-LINK Manual Version 3.2.4 2 Installation of the RAK-LINK Installation should only be carried out by a competent electrician. The connections to the RAK-LINK, as shown below are: 1. Mains AC connection to power supply 2. RJ45 patch lead to RAKs 3. Krone connector punch downs and RJ11 sockets to Wired network 4. Optional 3 x RJ11 sockets for Wired accessories RAK-LINK Manual Version 3.2.4 Step 1 Step 2 Step 3 RAK-LINK Remove the front cover and remove the plastic knockouts to allow cables to pass in and out of RAK-LINK. If RAK8-MB units are being used, slot the RAK-LINK housing into the RAK8-MB metalwork using the plastic rails. Screw RAK-LINK to the wall and prepare the mains supply cable. Remove the top tray by disconnecting the ribbon cable and screws Fix the lower tray into the wall-mounted metal housing using the screws indicated in the diagram. Manual Version 3.2.4 Step 4 Step 5 Step 6 RAK-LINK Wire the mains supply into the terminal block. Insert the RJ45 cable that links the RAK-LINK to a stack of RAKs. Prepare two remaining screws to be slotted into the top tray Reattach the ribbon cable between the top and bottom board Slot the top tray into the bottom tray and screw down Punch down the CAT5 to the Wired network to complete installation. If required, connect up to three Wired accessories (for example the WK-HUB) to the RJ11 ports Manual Version 3.2.4 3 Terminating the RAK-LINK The final step in the installation process is to terminate the RAK-LINK. The termination that is required depends on the nature of the installation and the position of the RAK-LINK within the System. No Term - Both Jumpers removed Used when the RAK-LINK is not at the end of line. This is usually identifiable by two cables being punched down to the RAK-LINK. Term - Jumper fitted across 1+2 & 4+5 Used when the RAK-LINK is end of line in a daisy chain configuration. Star Term - Jumper fitted across 2+3 & 5+6 Used when the RAK-LINK is end of line in a STAR wire configuration. 4 Programming the RAK-LINK The RAK-LINK is programmed using the Rasoft Pro programming software. A WK-HUB or WA/WTC-Bridge is required for any programming of a Wired System. For more information on how to program a RAK-LINK please refer to "Wired System Setup Guide" RAK-LINK Manual Version 3.2.4 Appendix 1: RAK-LINK diagnostics Requires ISSUE B circuit board and firmware version 0.4.6 RAK-LINK Blue LED Status Number Colour Indicates Blue Device activity Uses/example Device in setup Network looping poll 2 Blue Power/ CAN bus activity Solid Power detected Flashing CAN Bus Transmitting or receiving 3 Red CAN Diagnostics CAN warning CAN error Red LED Status Warning: RED LED Fast flash Cause: Incorrect voltages measured on the RAK-LINK data lines. The System may still function. Warning: RED LED Slow flash Cause: Power supply detected to be below 12V Error: RED LED solid Cause: CAN Transmission failure. The RAK-LINK has repeatedly failed to transmit a message. Troubleshooting (Potential causes) Continuously checked One or more data line(s) have been shorted to a power line. RAK-LINK put into setup mode with no network attached. The network is very busy (LED 2 will also be flashing fast). Continuously checked Power Supply failing. Power is supplied from another source. Checked on power-up and attempted transmission RAK-LINK put into polling mode with no network attached or CAN bus shorted together. Once the fault has been cleared, power cycle the RAK-LINK to clear the LED diagnostics. NB Caution should be exercised while using this table for diagnostic purposes. The suggested possible cause is the most likely of many possible outcomes but is not a guaranteed solution.
