However, in the case of RS485/RS422 port server will not be able to work properly in these modes, as they relate to the full
RS232 interface.

2.4. ISOLATION
ADA-14040 converter has 2-way galvanic isolation, depend on version of device, described at section VERSIONS.

3. INSTALLATION
This chapter will show how correctly connect ADA-14040 to RS485/RS422 network, Wi-Fi network and power supply.
To reduce disturbance from environment, it is recommended to:
–
use shielded twisted multipair type cables, which shield should be connected to the grounding on one end of the cable,
–
lay signal cables at a distance not less than 25 cm from power cables,
–
use suitable diameter cable for power supply on account of voltage drop,
–
use the interference eliminators for powering the converters installed in the range of some building,
– not powering the converters form power-circuit of devices generate large impulse disturbance like contactors, relays,
inverters.
