ADA-4040

2.2. DESCR PT ON
ADA-4040 separator-repeater is a device used for separation and extension of RS485/422 bus, about next segment 1200m (without
interference with data format). The distance is being reduced in case of large baud rate (over 115,2 Kb). The separator-repeater can
be used for communication with other, remote devices with RS485/422 interface eg controllers or scales; using the lines
RX+,RX-,TX+/A,TX-/B.
The ADA-4040 transmits data at baud rate up to 230,4 kbps, through four or two twisted-pair connected to a terminal block. To
RS485/422 bus created by the use ADA-4040, it is possible to connect 32 devices, operating in half duplex or full duplex mode. The
1kVDC or 3kVDC galvanic isolation and ~3kVDC optoisolation in signals line separate RS1/OUT (RS485/RS422) interface from
RS2/IN (RS485/RS422) interface. Protect a device connected to RS2/IN from overvoltage, which appear on RS485/422 bus,
connected to RS1/OUT and in the power-circuit.
Over-voltage protection on each RS485/422 lines, was made on the base overvoltage LED's and the fuses. The ADA-4040 should be
powered from the power supply stabilized voltage with a voltage in the range 10 - 30 VDC and minimum power 2W.

2.3. SOLAT ON
The separator-repeater ADA-4040 has (depend on version) 2-way or 3-way and 1kV= or 3kV= galvanic isolation. The descriptions are

3. NSTALLAT ON
This chapter will show how to connect ADA-4040 to RS485/422 bus and power supply and how to use it..
To reduce disturbance from environment, it is recommended to:
–use multi-pair type shielded cables, which shield can be connected to the earthing on one end of the cable,
–use the suitable diameter cable for power supply on account of voltage drop,
–use the powering cable with a suitable section because of the voltage drops,
–use the interference eliminators for powering the converter,
–lay signal cables at a distance of not less than 25 cm away from power cables,
–not powering the converters form the power-circuit of devices generate large impulse disturbance like contactors, relays, inverters.
3.1. ASSEMBL NG
The ADA-4040 case is adapted to assembly on TS-35 (DIN35) 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. CONNECT ON TO RS485/RS422 NETWORK
RS485/RS422 interface at ADA-4040 separator-repeater is available on terminal block described as: Tx+/A, Tx-/B, Rx+, Rx- ND.
ADA-4040 support operating on RS422 bus and RS485 (2-wire and 4-wire). Both buses need proper cabling.
3.2.1. EXTENS ON AND SEPARAT ON OF RS-485 / RS-422 BUS
Using the ADA-4040 it is possible to extend the RS485/422 bus of next segment 1200m and make the galvanic separation of next
segments of the bus. It increases the reliability of the system operation based on RS485/422 bus.
Example connections of the ADA-4040 are shown below.

3.2.2. GND TERM NAL CONNECT ON
Connection of ND terminals of RS485/422 interfaces, devices connected to RS485/422 bus, should be done in the case of a
potential difference of the signals grounds on interfaces RS485 / RS422, which prevents proper data transmission.
Cannot connect to the GND terminal - cables screens, PE circuit of electrical installation, signals grounds of other devices.
3.2.3. L NE TERM NAT ON
The application of Line Termination (terminator) Rt = 120 W (ohms) will reduce electrical reflection in data line at high baud rate. It is
not needed below 9600Bd. The Line Termination resistor should be used if the distance is over 1000m @ 9600Bd or 700m @
19200Bd transmission, the resistor can be necessary if there are problems with the transmission correctness. The
terminators/resistors are connected to the terminal block of ADA-4040 on the RS485/RS422 interface. Example connection of Rt are
shown on Fig. 3, 4, 5, 6, 7, 8, 9.
3.3. POWER SUPPLY
The power supply to ADA-4040 should be DC (regulated) from the scope 10 V= to 30V= and nominal power 2W. The power cable
from DC power supplies to the device must not be longer than 3m. Observe the polarity, connect positive (+) of DC power supplies to
V+ and negative (-) end to V- terminal. ADA-4040 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. CONF GURAT ON
For configuration of ADA-4040 operating mode use a six-position dip switch SW1.
The SW1 is located next to RS485 terminal block (Fig.1) under the cover. For setting, remove the cover and use small, flat
screwdriver.
4.1. OPERAT NG MODE SETT NG
The setting of SW1 dipswitch for operating mode of ADA-1040 is shown in the Table 1 (below).
