2.2. DESCRIPTION
Multidrop Fiber Optic Converter ADA-7240 is used for creation of fiber optic bus, for connection of RS485/422 interface devices quite
distant from each other eg. Computers, controllers etc. Conversion between fiber optic RS485/422 is without interfering with the data
format. The use of fibre-optic provides complete isolation between connected devices and resistance to interference on the
transmission bus. Fiber optic connection is made by the use of two fibres. ADA-7240 can be use also for extend the fiber optic bus for
next part 2500m because the converter also complies functions of fiber optic repeater.
ADA-7240 is equipped with screw terminal block for connection of RS485/422 and power connections. It supports baud rates up to
2Mbps on 2-wire or 4-wire RS-485 bus via one or two pairs of twisted pair, connected to the screw terminals block. The device uses to
operate lines RX +, RX-, TX +, TX-.To RS485 bus built on the ADA-7240 can be connected 2 devices operating in half duplex mode
or full duplex mode and to RS422 bus two devices operating in half duplex mode. Overvoltage protection was made on base safety
diodes and fuses on each RS485/RS422 lines.

3. INSTALLATION
This chapter will show how to connect ADA-7240 to RS485/422 bus, Fibre-Optic and power supply and how to use it.
In the purpose of minimization of disruptions from environment is being recommended to:
●apply 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,
●apply cable of adequate cross-section due to voltage drops for converter powering,
●use Interference suppression filters for power supply converters that are installed within a single object.
●not supply converter from power circuit device that generates large impulse interference such as transmitters, contactors,
3.1. ASSEMBLING
The ADA-7240 converter case is adapted to assembly on TS- 5 (DIN 5) rail. To install converter should mount device on the rail
upper part of the case then press bottom part to hearing characteristic „Click” sound.
3.2. CONNECTION TO RS485/RS422 BUS
RS485/RS422 interface at ADA-7240 converter is available on terminal block described as: Tx+/A, Tx-/B, Rx+, Rx-. ADA-7240 support
operating on RS422 bus and RS485. Both buses need proper cabling.

3.3. CONNECTION FIBRE-OPTIC BUS
The multimode Fibre-Optic with connectors type: ST®, SC or SMA, connect into their corresponding converter's connectors type: ST®,
SC or SMA like on the Fig. 6. Connecting the fiber optic cables should be cautious and careful not to damage them or dirty. If it is
necessary to lay the cable at an angle, must be created the appropriate bends.
ATTENTION!!!
The devi e is equipped in the laser transmitter.
The radiation emitted by the laser transmitter is harmful to the eyes!
Under no ir umstan es should never look to at the un overed slot, to whi h it is not onne ted the fiber opti

3.4. POWER SUPPLY CONNECTION
The power supply to the ADA-7240 converter should be DC (regulated) from 10 V= to 0V=. 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 m.
Observe the polarity, connect positive (+) of DC power supplies to V+ and negative (-) end to V- screw terminal block. ADA-7240 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-7240 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. OPERATING MODE SETTING
