3 Module DIP Switch Configuration
3.1 Addressing (4 DIP Switches)
Each Switch LED Module must be connected to the Axis
AX
panels P-BUS (RS-485 serial communication bus),
located on the AX-CTL base card. As the Switch LED Modules reside on the AX-CTL P-BUS, each module must
be configured with a unique address (see figure 6). The address setting corresponds to P-BUS programming criteria
utilized within the Advanced PC-NeT, field configuration program.
As previously stated, up to 16 (sixteen) Switch LED Modules (any combination) can be connected to a single Axis
AX
AX-CTL base card, P-BUS.
Note: Only 16 (16) Switch LED Modules can be connected to a single Axis
AX
AX-CTL base card.
3.2 485 Comms EOL & Disable PSU Monitor (2 DIP Switches)
In addition to the DIP switches provided for module addressing, each Switch LED Module has two additional DIP
switches, DIP switch 6 and 7. DIP Switch 6 is for activating an onboard resistor to allow for AX-CTL base card P-
BUS (RS485) end-of-line filtering. Dip switch 7 is for allowing the monitoring of a remote power supply.
3.2.1 485 Comms (P-BUS) EOL
The P-BUS (RS485 communications bus) of the AX-CTL base card requires a 150
Ω
end-of-line filtering resistor to
be placed on the last (furthest) P-BUS module connected to this Style 4 (Class B) communications bus. If a Switch
LED Module is the last module on the P-BUS, set DIP switch 6 on the module to “ON”, thereby activating the
internal 150
Ω
end-of-line filtering resistor (see figure 6). If the Switch LED Module is not the last module on the P-
BUS, leave DIP switch 6 in its “OFF” position.
Note: DIP switch 6 on the Switch LED Module should only be in set to its “ON” position if the Switch LED
Module is the furthest (last) P-BUS module from the Axis
AX
AX-CTL base card.
