What is the RAK-LINK?
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.
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:
- Mains AC connection to the power supply
- RJ45 patch leads to RAKs
- Krone connector punch downs and RJ11 sockets to Wired network
- Optional 3 x RJ11 sockets for Wired accessories.
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 the 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 the line in a daisy chain configuration.
Star Term – Jumper fitted across 2+3 & 5+6
Used when the RAK-LINK is the end of the 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 the “Wired System
Setup Guide”

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.
