Remark about the 5 pol connector for power supply and RS-485
The above described mounting position of the 5 pol connector of the 24VDC and RS-485 connector
(24VDC pins are on the side where the RJ45 Ethernet connector is plugged) was introduced since
hardware version B of the PCD7.D443WTxRx
On the hardware version A of the PCD7.D443WTxRx the whole 5 pole connector is mounted 180°
inverted, means that the 24VDC pins are not on the side where the RJ45 Ethernet connector is
plugged.
The 5 pol connector is the same for the hardware version A and version B, and the Pin numbering
on the connector is the same on both hardware version.
(Pin 1 = 24VDC, Pin 2 = GND, Pin 3 = D RS-485, Pin 4 = GND RS-485, Pin 5 = /D RS-485)
That means, when replacing a panel from hardware version A to hardware version B, there is no
need to change the wiring at the connector. Only insert the connector by 180° inverted.
