DLT-V72 Operating Instructions V2.50 Preliminary 113 / 140
13.1.4. 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.
13.2. Under the antenna
NOTICE: Physical damage
Improper opening of the antenna can impair the function of the entire DLT-V72 system and in
particular the Wi-Fi functionality.
The antenna may only remain open for the duration of the service work.
No objects or liquids may enter the opened DLT-V72 during this.
Only when the antenna is properly closed again may operation be resumed; the protection
class/category is only ensured again after doing so.
13.2.1. Service USB
There is a service USB interface under the antenna. It can be used for service purposes, e.g. to install
software updates.
− USB 3.0 SuperSpeed
− Fused at 1.0 A per channel
− ESD Level 4 protected (according to EN 61000-4-2)
A plug connector which meets the specific shock and vibration requirements is used for the service USB
interface.
 Exercise special care when removing and plugging in USB connectors.
