====== 2.5 IOL Ports and LEDs ======

{{:iol-hat:hw-pro:2_connections:2-3-1_connectors.png?400&direct}}

Both IOL ports use the same pin-out. For industrial use, the signal lines on the SDCI ports have improved surge immunity. Each port features a bi-color LED for signalization of the operation mode. The typical M12 cable coloring scheme for pre-configured cables is listed.

^ Pin # ^ Usage ^ M12 cable color ^
| 1 | L+ (24V) | brown |
| 2 | DIA (Input/Output line) | white |
| 3 | GND | blue |
| 4 | CQ (Serial line) | black |

The connector is 4pin, 3,5mm MC-type

<WRAP Important>

Each IOL Port is designed to supply max. 500mA on the L+ line and 150mA on the CQ line. The current supply is limited by software (for L+ in connection with a series resistor). If a custom master application is used, the limits must be set in the driver configuration.
