DTECH Serial to Ethernet Converter Adapter RS232 RS422 RS485

This product is a RS232/ RS422/ RS485 to TCP/ IP serial port server, with internal integration of TCP/ IP protocol stack , which can realize two-way transparent transmission
of network data packets and serial data , with TCP CLIENT, TCP SERVER , UDPCLIENT, UDP SERVER , etc. Four working modes , the serial port baud rate can support up to
115200bps , which can be easily configured through the host computer software that this product is equipped with , which is convenient and fast. Products are widely used in
industrial automation control systems , access control systems , time and attendance systems , credit card systems , POS systems, building automation systems, power
systems , monitoring systems, data acquisition systems andbank self-service systems.

Product parameters
1. Built-in Ethernet media transport layer (MAC) and physical layer (PHY)
2. DHCP (Dynamic Host Configuration Protocol) This function enables the serial
port server to obtain its dynamically assigned IP Address through the DHCP
Server,which can avoid IP address conflicts in the internal network segment.
3. Realize two -way transparent transmission of serial port data and network data
4. Support DHCP to automatically obtain IP address, support DNS domain name
access
5. The serial port baud rate supports 300bps～115200bps
6. RS232: support serial port RS232
7. RS422: Full duplex RS422 communication
8. RS485: Half-duplex RS485
9. Maximum connection of 256 RS485 devices, RS422 standard can only connect 10
devices, RS232 standard can only connect 1 device
10. Button function: long press the button before power-on, and release the button
after power-on for 5 seconds to restore the factory settings
11. Support 10/ 100M, full-duplex/half-duplex adaptive Ethernet interface,
compatible with 802. 3 protocol
12. Support “non -standard ” and “standard ” POE power supply (4, 5 and 7, 8 and
1, 2 and 3, 6 power supply mode switches)
13. Support Modbus RTU/TCP two -way transparent data transmission
14. With DC 9 ~ 35V power output (the output voltage is determined by the input
voltage, not related to the POE voltage)
