3. INSTALLATION
This chapter will show you how correctly connect ADA-4010A to Computer, RS485 and RS422 network, power supply and how to use
the ADA-4010A.
In the purpose of minimization of disruptions from environment is being recommended::
applying multipair type shielded cables, which shield can be connected to the earthing on one end of the cable,
–
arrange signal cables in the distance not shorter than 25 cm from powering cables.

3.1. CONVERTER ASSEMBLING
ADA-4010A case is adapted to assembly on TS-35 (DIN35) rail. To install converter you should mount device on the rail upper part of
the case then press bottom part to to hearing characteristic „Click" sound.
3.2. COMPUTER CONNECTION
To connect ADA-4010A converter to:
– RS232 port of computer you should make a cable according to schema on Fig.3,
– USB port of computer you need additional converter USB to RS232 e.g. ADA-I9110 converter or ADA-I9111 converter. Typical
connection of ADA-4010A to PC is shown on Fig. 4.
