2.3.4. OTHER COMMUNICATION MODES
ADA-13028L converter can be configured in other communication types, like:
– terminal mode,
– modem emulation mode,
– console mode,
– user mode.
However, in the case of Current Loop CLO converter, it will not be able to work properly in these modes, as they relate to the full
RS232 interface.
2.4. CURRENT LOOP TRANSMITTER & RECEIVER
ADA-13028L converter is produced with active or passive Current Loop transmitter.
The converter with CLO active transmitter has the transmitter on base power source generating the power with value specified in the
converter versions and passive receiver comprising the optocoupler. ADA-13028L with CLO passive transmitter has the transmitter on
base transistor switch and passive receiver comprising the optocoupler.
2.5. ISOLATION
ADA-13028L has 3-way galvanic isolation on the level 1kV= or 3kV= - depends on version.

3. INSTALLATION
This chapter will show how correctly connect ADA-13028L to devices with Current Loop CLO interface, LAN/WAN 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.
3.1. ASSEMBLING
ADA-13028L converter case is adapted to assembly on TS-35 (DIN35) rail. To install the device on TS-35 should be the upper part of
the casing put hooks on the terminal and then press the bottom of the cover until you hear a characteristic "Click" sound.
3.2. ETHERNET NETWORK CONNECTION
ADA-13028L has to be connected to ETHERNET network by the use of the switch, the HUB or directly to the PC network adapter.
The table below shows preparing of the straight cable for converter connection to switch or hub.
