● Rail mounting according to DIN35 / TS35 standard,

● Dimensions (W x D x H) 53mm x 62mm x 90mm.

2.2. DESCRIPTION

The ADA-4044H HUB is used for creation star-branches from the main bus and also separation and extending of RS485/RS422 bus

for next segment 1200m without interfering with the format of transmitted data. The HUB has one input RS485 port (RS485-IN) for

connection of main bus and 4 separated output ports for connection of 2-wire bus or 2 ports for connection of 4-wire of RS485/422

bus. To each output port can be connected a RS485 bus branch, having up to 32 devices. The setting of a port type is made, by the

use of a RS-485 PORTS microswitch, located on the front panel. HUB ADA-4044H can be used for communication in star-topology

with devices in different location and distance, where RS485 chain-topology is difficult or impossible.

To RS-485-OUT ports can be connected up to 64 devices in case of 4-wire RS485 bus, 128 devices in case of 2-wire RS485 bus and

2 addressable devices RS422.

ADA-4044H baud rate is up to 230,4 kbps via 4 or 2 pairs or twisted pair connected to screw terminal block. To 2-wire RS485 bus can

be connected devices operate in half duplex mode and to 4-wire operate in half duplex & full duplex mode. It can be PLC, measuring

devices, electronic scale and cash registers with RS485 or RS422 interfaces.

A surge protection on each RS485/RS422 line was made on the basis of surge diodes and fuses.
