Fig. 6. Example connection of ADA-7040 converters by the use of Fibre-Optic line.
3.4. POWER SUPPLY CONNECTION
The power supply to the ADA-7040 converter should be DC (regulated) from 10 V= to 30V=. Nominal power is typically 2W, e.g. ZS-
12/250 or DR-15-24. Power cable from DC power supplies to device must not be longer than 3m.
Observe the polarity, connect positive (+) of DC power supplies to V+ and negative (-) end to V- screw terminal block. ADA-7040 has
the protection from opposite connection power supply. If after power, on the front panel is not lit green LED PWR, check the power
connection (polarity).
4. CONFIGURATION
The operating mode of the ADA-7040 converter is set by the use 6-position SW1 switch. This switch is located near the Fibre-Optic
connectors (see Fig.1). To set the SW1 should remove the terminal cover and using small, flat screwdriver make correct setting.
4.1. SETTING OF OPERATING MODE
All available operating modes are shows in table below.
If there are any additional questions, please contact with technical support: suppor@cel-mar.pl or on the phone: +48 41 362-12-46.

5. ACTIVATION
Converter can be powered after proper connection according to steps above.
If connection was made properly green LED PWR on front panel of converter should light, if not check polarization of power
connection. During proper data transmission through converter the LEDs Tx and Rx should blink.
