1.1. WARRANTED INFORMATION The ADA-1044H converter is covered by a two year warranty from date of sale. In case of being damaged it will be repair or the damaged component will be replace. The warranty does not cover damage caused from improper use, materials consumption or any unauthorized changes.
This converter has one RS232 port for connection Master device (PC, PLC-MASTER) and four separate RS485-ports for 2-wire bus or two RS485/422 for 4-wire bus. The setting of port type is by 'RS-485 PORTS' switch on the front panel. ADA-1044H can be used also for communication with devices in star topology located in different places where RS485 chain topology is impassible.
Fig 2. Isolation structure 3. INSTALLATION This chapter will show you how to connect ADA-1044H to PC or controller with RS232 port, RS485/422 network and power supply. In the purpose of minimization of disruptions from environment is being recommended to: ●...
Fig 5. DCE type connection of ADA-1044H to device with RS232 interface (eg. modem) 3.3. CONNECTION TO RS485/RS422 BUS RS485/RS422 interface at ADA-1044H is available on terminal block described as: Tx+/A, Tx-/B, Rx+, Rx- (IN) and T1+/A1, T1-/B1, R1+/A2, R1-/B2, T2+/A3, T2-/B3, R2+/A4, R2-/B4. RS485/422 bus need proper cabling.
3.3.1. STAR-TYPE CONNECTION FOR 4-WIRE RS485 BUS Using the ADA-1044H, configured for operating with 2-ports, 4-wire RS485 (the 'RS-485 PORTS' switch should be set in 4W position and 'SW1” switch should be set in RS485 position), it is possible to make : - star-type connection of up to 64 devices with 4-wire RS485 interface, - galvanic separation of RS232 port from RS485 Bus.
3.3.2. STAR-TYPE CONNECTION FOR 2-WIRE RS485 BUS Using the ADA-1044H, configured for operating with 4-ports, 2-wire RS485 (the 'RS-485 PORTS' switch should be set in 2W position and 'SW1” switch should be set in RS485 position), it is possible to make : - star-type connection of up to 128 devices with 2-wire RS485 interface, - galvanic separation of RS232 port from RS485 Bus.
3.6. POWER SUPPLY CONNECTION The power supply to ADA-1044H should be DC (regulated) from the scope 10 V= to 30V= and nominal power more than 2W e.g. DR- 15-24. The power cable from DC power supplies to the device must not be longer than 3m.
4.2. SETTING OF TYPE AND NUMBERS OF PORTS RS485 IN Converter ADA-1044H has on front panel the switch RS-485 PORTS (see fig.1), which is use for selection of type and numbers of RS485 ports. Available ports type: 4W – four-wire, 2W – two-wire.
