2.1 Connections overview
The following image provides an overview on the available connections and interfaces:
All logic signals (SPI, interrupts) on the 40-pin GPIO and the generic interface X3 work on 3V3 logic levels.text/html2025-04-16T19:17:03+00:00Anonymous (anonymous@undisclosed.example.com)2.2 40-pin GPIO to Raspberry Pi and jumper settings (PT-1201 only)

2.2 40-pin GPIO to Raspberry Pi and jumper settings (PT-1201 only)
This connector provides the connection to the Raspberry Pi over the standard 40-pin GPIO connector:
This connector is implemented as stack-through, i.e. up to two IOL HATs can be connected on top of each other. If the pins are not occupied by the connected IOL HAT, additional expansion boards can be connected via the stack-through connector.text/html2026-01-18T11:51:23+00:00Anonymous (anonymous@undisclosed.example.com)2.3 Generic Interface (PT-1202 only)

2.3 Generic Interface (PT-1202 only)
The 40-pin connector is not populated, the X3 connector is populated with the pin header. Selection over the jumpers is not possible. The interface to the host system is on X3 with the following pin assignments:text/html2025-04-16T19:20:53+00:00Anonymous (anonymous@undisclosed.example.com)2.4 SDCI Ports and LEDs
https://doc.pinetek-networks.com/doku.php?id=iol-hat:hw:2_connections:2.4_sdci-leds&rev=1744831253&do=diff
2.4 SDCI Ports and LEDs
Both SDCI 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.text/html2025-04-16T19:21:36+00:00Anonymous (anonymous@undisclosed.example.com)2.5 24V-Input
https://doc.pinetek-networks.com/doku.php?id=iol-hat:hw:2_connections:2.5_24v-input&rev=1744831296&do=diff
2.5 24V-Input
The 24V power supply input is used for the L+ supply of the SDCI ports. The logic part of the module is supplied over the 3V3 on the 40-pin GPIO connector or the generic connector.
The connector is 2pin, 3,5mm MC-type
Depending on the connected SDCI devices, the 24V input can consume up to 1,3A current. Please use adequate cabling. The port is not hardware overcurrent protected, the L+ lines and CQ-lines shall be current limited by the driver in software.
