This item can convert RS-232 signal of single end into RS-422 or RS-485 signal of balanced difference. It can offer isolation voltage of 3500V; quick transience voltage suppresser (TVS) may effectively suppress lightening; and 600W lightning and surge protective power og each line input by ESD may effectively prevent from lightning and disturbance of common place.

RS-232 interface connects with computer serial port through a linker with a DB9 female din, with RS-232/RS-485 end connecting with computer through DB9 pinhead or six-digit connecting terminal convenient to plug in or draw out. Due to the fact that RS-485 supports double line half duplex, namely, data shall be both sent and received through the only lines of RS-485, handshaking signal usually controls the direction in which data is sent, and the circuit inside the optical isolation interface converter may apperceive data flow direction and switch enable control automatically. A RS-485 network can be formed conveniently without any handshaking signals; and the RS-485 enable control is completely point transparent, dispensed with modifying any software for the past operation method based on RS-232.

This optical isolation interface converter may offer reliable connection for communications from one point to point or ine point to points, and the latter allows connecting with 32 RS-422 or RS-485 interface equipments, with speed of data communication from 300 to 115.2kbps.
The three indicator lights indicate communication circumstance of data flow timely, and the supported communication method includes conversions from RS-232 to RS-422 and from RS-232 to RS-485. It is widely used in industrial automatic control system, one card universal gata inhibition system, park system, automatically bank system, bus charging system, restaurant sale system, personnel attendance management system, highway toll station system, etc.

Interface feature: concurrently with RS-232M and RS-485/RS-422 standard of EIA/TIA;
Electric interface: RS-232M interface with 1 DB9 port, RS-422/RS-485 interface with DB6 female linker and equipped six-digit connecting terminal.
Transmission media: shielded twisted pair
Operation method: Asynchronous half duplex or four-step full duplex.
Signal indication: two indicator lights TXD,RXD,POWER
Isolation degree: isolation voltage: contentious 3500VRMS,5600VDC;
Protection degree: RS-232 interface with protection of ±15KVESD,RS-422/RS-485 with protection of 600W lightning strike and surge power of each line.
Transmission speed: 300-115.2kbps.
Transmission distance: 0-5KM
Dimension: 90mm*65mm*25mm

Power supply and surge grounding protection
External power supply HXSP-2108M optical interface converter can adopt 9V power supply adapter matched with product to supply electricity, also can supply power from other DC source or equipment, power supply voltage is +97 and electrical current is 100MA.
Surge grounding protection: common interface
Converter is not provided with protection device of largeenergy due to the transient high pressure of circuit inductionon interface data line, try to release energy from minimumresistance path of equipment to ground wire, therefore, it iseasy to result in samage on interface components. Opticalisolation converter can provide each line with 600W protective power of lightning stroke, rapid transient voltage suppresserinterface converter should be connected to ground reliably andavoided to hang in the air in order to guarantee communicationsafety during use.

Package Includes
1x RS232 to RS-422 RS-485 Optical Isolation Interface Converter
1x US/EU AC-DC Power Adapter
1x 2M UTP 4Pairs 24AWG Patch Cable
