BLACK BOX® यूनिवर्सल RS-232 से RS-422/485 कन्वर्टर ऑप्टो-आइसोलेशन के साथ RS-232 संकेतों को RS-422/RS-485 संकेतों में और इसके विपरीत अलग करता है और परिवर्तित करता है। अन्य कन्वर्टर्स के विपरीत, डेटा फ्लो को नियंत्रित करने के लिए बाहरी सॉफ़्टवेयर की आवश्यकता नहीं होती। RS-232 इनपुट को DB9 महिला कनेक्टर के माध्यम से DCE के लिए वायर किया गया है, और RS-422/RS-485 संकेतों को एक हटाने योग्य टर्मिनल ब्लॉक के माध्यम से इंटरफेस किया गया है। टर्मिनल ब्लॉक को बाहरी पावर प्रदान करने के लिए, आपको हमारी 120-VAC/12-VDC वॉलमाउंट पावर सप्लाई (PS1003) की आवश्यकता है।

RS-232 के लिए, कनेक्शन RD, TD, और सिग्नल ग्राउंड की आवश्यकता होती है।

RS-422 मोड में, ड्राइवर हमेशा पूर्ण-द्विमासी संचार के लिए सक्षम रहता है। ट्रांसमिट के लिए एक ट्विस्टेड पेयर की आवश्यकता होती है, और रिसीव के लिए भी एक ट्विस्टेड पेयर की आवश्यकता होती है। एक ग्राउंड रेफरेंस वायर की भी आवश्यकता होती है। स्विच सेटिंग्स हैं स्विच 1: RS-422; स्विच 2: इको ऑन; स्विच 3 और 4: 4 वायर।

दोनों RS-485 मोड में, RS-485 ड्राइवर स्पेस स्टेट के दौरान RS-232 सिग्नल की उपस्थिति द्वारा स्वचालित रूप से सक्षम होता है। जब RS-232 डेटा मार्क या आईडल स्थिति में होता है, तो RS-485 ड्राइवर बंद हो जाता है और RS-485 डेटा लाइनों को 4.7-ओम रेजिस्टर द्वारा प्रदान किए गए बायस द्वारा मार्क स्थिति में रखा जाता है; इस रेजिस्टर का मान, आपके द्वारा उपयोग किए जाने वाले टर्मिनेशन के आधार पर बदलने की आवश्यकता हो सकती है।

कई RS-485 डिवाइसों से न्यूनतम वायर के साथ कनेक्ट करने के लिए, यूनिट के 2-वायर, हाफ-डुप्लेक्स RS-485 मोड का चयन करें। जब डेटा अनुरोध किया जाता है, तो पता की गई डिवाइस प्रसारित करती है और फिर रिसीव स्थिति में वापस लौटती है। इस मोड के लिए स्विच सेटिंग्स हैं स्विच 1: RS-485; स्विच 2: इको ऑफ; स्विच 3 और 4: 2 वायर।

4-वायर मास्टर/स्लेव सर्किट के लिए, यूनिट के 4-वायर, पूर्ण-द्विमासी RS-485 मोड का चयन करें। इस मोड में, पता की गई डिवाइसें डेटा प्राप्त कर सकती हैं जबकि पहले के अनुरोध से डेटा प्रसारित कर सकती हैं। एक एकल-मास्टर प्रणाली में मास्टर के रूप में उपयोग करते समय, स्विच 1 को चुना जा सकता है क्योंकि यूनिट प्रणाली में केवल ट्रांसमीटर है। RS-485 स्लेव के रूप में उपयोग करते समय, RS-232 डिवाइस को पता लगाने की क्षमता प्रदान करनी चाहिए। मास्टर/स्लेव सिस्टम में बायसिंग लाइन के अंत में स्लेव द्वारा प्रदान की जाती है। इस मोड के लिए स्विच सेटिंग्स हैं स्विच 1: RS-485; स्विच 2: इको ऑन; स्विच 3 और 4: 4 वायर।

FAQ
The Black Box Universal RS-232 to RS-422/485 Converter features 2000-VAC isolation, selectable RS-422 operation, RS-485 support for both 2-wire half-duplex and 4-wire full-duplex modes, and automatic RS-485 driver control. It doesn't require external software for data flow control and comes with a DB9 female connector for RS-232 input and a removable terminal block for RS-422/RS-485 signals.
The converter has compact dimensions measuring 1.7 inches in height, 0.9 inches in width, and 3.9 inches in depth. It features an external form factor design that makes it easily accessible and installable.
In RS-485 mode, the driver is automatically enabled during each space state by RS-232 signal presence. When RS-232 data is in mark or idle state, the RS-485 driver disables and data lines are held in mark state by a 4.7-ohm resistor. It supports both 2-wire half-duplex and 4-wire full-duplex operations, with specific switch settings for each mode.
The converter requires external power supplied through a terminal block connection. It specifically needs a 120-VAC/12-VDC Wallmount Power Supply (PS1003, sold separately) to function properly.
The converter is RoHS certified and TAA compliant. It's environmentally friendly and manufactured in the United States, meeting various regulatory standards for electronic equipment. The 2000-VAC isolation certification ensures robust protection between input and output circuits.
For RS-422 mode configuration, set Switch 1 to RS-422, Switch 2 to Echo On, and Switches 3 and 4 to 4 Wire. In this mode, the driver is always enabled for full-duplex communications, requiring a twisted pair for transmit, another for receive, and a ground reference wire.
The Black Box Universal RS-232 to RS-422/485 Converter comes with a 1 Year Limited Warranty, providing coverage against manufacturing defects and ensuring customer support during this period.
In 2-wire half-duplex RS-485 mode, the device allows connection to multiple RS-485 devices with minimal wiring. The configuration requires Switch 1 set to RS-485, Switch 2 to Echo Off, and Switches 3 and 4 to 2 Wire. In this mode, devices transmit data when requested and then return to receive status.
