## Description

DT-9000 DT-9000 Manual of Commercial grade interface converter with lightning protection Ⅰ. Overview The DT-9000 converter is compatible with RS-232, RS-485 standard, to convert the RS-232 signal into RS485 signal, built in rapid transient voltage suppressor protector TVS; no need external power supply, the internal adopts the unique "RS-232 charge pump" to drive the whole circuit; circuit with zero delay automatic transceiver conversion unit, I/O circuit with preventing collision can automatically control data flow direction, thereby ensuring the program under the mode of RS-232 need not be changed, can be safely running in RS-485 mode, fully ensure to be suitable for existing software and hardware interface. Ⅱ. Performance parameter 1, Interface characteristics: interface compatible with EIA/TIA RS-232C, RS485 standard. 2, Electrical interface: RS-232 end DB9 hole type connector, RS-485 end DB9 needle type connector, with terminal. 3, Work mode: asynchronous half duplex differential transmission. 4, The transmission medium: twisted pair cable (wire diameter greater than or equal to 0.5MM) or shielded wire. 5, The transmission rate: 300-115.2KBPS 6, Size: 64mmX33mmX17mm 7, working environment:: -20℃ to 70℃, relative humidity of 5% to 95% 8, The transmission distance: less than 1200 meters (RS-485 end), within 15 meters (RS-232 end) 9, The protection of lightning surge protection grade: RS-485 interface of each line is 600W 10,Two kinds of communication modes: point to point / two line half duplex and point to multipoint / two line half duplex Note: in order to prevent the signal reflection and interference, need to be connected with a matching resistor in the circuit terminal (parameter 120Ω 1/4W), depend on the situation.

## Questions & Answers

**Q: Does this device support node addresses on the rs485 network? seems not, so how do i address a particular device?**
A: Your RS-485 end device has to handle the addressing. This device simple converts RS-232 to RS-485. Any RS-485 devices hanging on the other end have to have their own addressing scheme via the protocol you're using.

**Q: Does it work with modbus ascii rs485 devices?**
A: Yes, this RS-232 to RS-485 adapter works for modbus ascii rs485 devices. If there is any usage issue, please feel free to contact us via the order anytime.

**Q: Does the baud rate auto-detect work if the RS232 side listens only (no transmission)?**
A: Only there is signal transmission between RS232 and RS485, the baud rate will be auto detected.

**Q: Does this do 485 to 232?**
A: Yes, I used this converter for Modbus communication from rs-485 to rs-232.

I couldn't ask for more, this thing works great! I needed to send some commands to an RS-485 peripheral to provision it, and it worked perfectly. Its totally bus powered (but provides option for external 7-9vdc power on the RS-485 side). The most important thing when using RS-485 half duplex is fast control of the DE (driver enable) line. This thing handles it automatically and perfectly. Able to send RS-485 commands via terminal and when not sending it releases the transmit line quickly to switch back to receive (<1ms). I was originally contemplating putting one of these together out of a RS-485 transceiver IC, and piddling some TTL stuff together to handle the DE line switching, but for this price, I couldn't justify spending the time building it even if the components were free and sitting on the shelf. A good RS232-485 converter is a handy thing to have in your toolbox for debugging if you work with any RS-485 devices, and this one is well built and super easy to use (it even came with a phoenix style screw terminal block, lol)
