Advantech-DLoG DLT-V8312 - COM1 as Voltage Source; COM2 EIA-422;485 Interface

Serial interfaces
Page 122 of 178 DLT-V83 Series Manual V1.31 Advantech-DLoG
The DLT-V83 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.
11.1. COM1 as a voltage source (optional)
The COM1 interface can optionally supply to externally connected equipment with +5 V
or +12 V of power. The voltages are protected by internal fuses and may not exceed a
continuous consumed current of 1 A at 5 V resp. +12 V.
Depending on the connected devices, the maximum current consumption may be
significantly lower.
11.2. COM2 as EIA-422/485 (optional)
A basic function (RX, TX) EIA-422/485 interface can be integrated optionally into the
DLT-V83 as serial interface.
