112 / 140 DLT-V72 Operating Instructions V2.50 Preliminary
13.1.1. 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:

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.
13.1.2. USB, Service-USB
USB connection, for example for mouse, keyboard, USB stick:
− 4 x USB 2.0 Host
− USB 2.0 Hi-Speed
− Fused at 1.0 A per channel
− ESD Level 4 protected (according to EN 61000-4-2)
13.1.3. COM1 and COM2
The DLT-V72 is equipped with two externally accessible serial interfaces COM1 and COM2.
Resources for the serial interfaces are pre-defined in the system architecture and automatically
managed by the BIOS.
