Detailed Product Description

RS-232/RS-485/RS-422

Fiber Optic Modem

User Manual

1,Overview of Product

HSGQ MODEM serial product supports the mutual conversion of asynchronous RS-232,RS-422,RS-485 corresponging interface and Fiber. It is the best choice for controller connecting Remote Terminal Unit(RTU) TO HOST or Supervisory Control And Data Acquisition (SCADA).

HSGQ MODEM serial product supports the Asynchronous Serial Communication Protocal among RS-232.RS-422.RS-485,simultaneously it can be worked with two multi RS-232,RS-422 or RS-485 interface,which supports the working model of 2 wires (half duplex) and 4wires (full duplex) RS-485.

HSGQ MODEM serial product with RS-485 supports the conrol of transmission of data (TXD or SD), hence which enchances the the performance of various software, simplifies the way of control .HSGQ MODEM serial product supports the connecting way of mutil fiber with asynchronous serial interface,it supports two asynchronous serial interface through fiber to work with full duplex or half duplex.

The maximum transmission speed of RS-232 signal is 115.2KBPS,.The maximum transmission speed of RS-422/RS-485 is 460KBPS.The different electrical interfaces can be used mutually together,For example The RS-232 device can connect RS-422/RS-485 device.HSGQ MODEM serial product can substitue the converter of RS-232/RS-485 interface or photoelectric isolator, providing the favorable performance of EMI/RFT.
