How to Set the Internal Jumpers and DIP Switches (Cortex 360)

Jumpers and switches location on the Cortex 360 main board

1 – Relay/open-collector outputs

The Cortex-360 can control its physical relays, or the transistors acting as relay drivers (open-collector mode).
By default, the eight relay jumpers are set for direct relay operation (RLY position). If you need open-collectors, change the jumpers of the desired relays to OC Mode.

2 – Status input

The status inputs can all be individually set for separate grounds or for internal grounds with pull-up resistors. DIP Switches S11 and S12 select isolated grounds mode (Default is NO on all 16 inputs). DIP switches S9 and S10 select pull-up resistor mode (it is IN by default on all 16 inputs).

3 – Metering input

The Cortex-360 metering inputs can be configured for 4-20 mA operation. To select this mode, place the jumper for the desired metering input in the ON position. By default, the metering input jumpers are set for voltage measurement (OFF position).

4 – IOIOI

This serial port can be configured for RS-232, RS-422 or RS-485 operation. By default, the jumpers are set for RS-232 operation.
