Only 4connections are required, +12V, 0V, A and B data. If the Keyprox is the lastmodule on the A B RS485 data bus, then a 680 ohm end of line resistormust be fitted across the A and B terminals.ConfigurationThe Keyprox is configured onto the Galaxy panel as two separate modules,a keypad and a MAX reader. Before powering up the Keyprox, the addressmust be set using the rotary switch on the back of the PCB. This addresswill apply to both the Keypad and the MAX Reader sections. It is theinstaller’s responsibility to ensure that the address set is compatible withthe system in use. Not all addresses are acceptable to all Galaxy panels.Reference to the installation instructions of the Galaxy panel isrecommended.Once the address has been set and the Keyprox has been powered up, itmust be configured onto the Galaxy system. This is done automatically onleaving programming mode, or by repowering the system. When configuredcorrectly, the system will show that two modules have been added, akeypad and a MAX reader, both with the same address.Keypad ProgrammingThe keypad side of the Keyprox requires no programming for mostinstallations.
