COM1 as a voltage source
The COM1 interface can optionally supply to externally connected equipment with
+5 VDC. The voltages are protected by internal fuses and may not exceed a continuous
consumed current of 1 A at 5 V. Depending on the connected devices, the maximum
current consumption may be significantly lower.
Using the DLoG Config tool, you can select whether "+5 VDC" or "RI" is output on pin 9
of COM1.
Network adapter (10/100/1000)
The DLT-V72 is equipped with a 10/100/1000 Mbit network adapter with
10/100/1000 Mbit per second. This adapter can be accessed via the bottom of the device
and offers an RJ45 connection jack. The RJ45 connection port has two integrated status
LEDs and are assigned as follows:
Left LED (green):
LED off: no connection
LED on: connection (link)
Problems with data transmission via LAN/Ethernet
If problems occur during data transmission over LAN/Ethernet (e.g. data is lost or not
detected), the cause of these problems may be a cable which is too long. Depending on
the cable layout and interference from the environment, it may be impossible to use the
cable length of 100 m given in the specification (IEEE 802.3 standard). The solution here
is the use of a shorter cable.
