EX952N Series (Addressable RS422/485 to RS232 converter)
EX952N Quick Manual
Introduction
EX952N is an Addressable RS422/485 to RS232 converter that it is designed to
connect RS422/485 devises to an RS232 network.
On most computer systems, industrial device, PLCS, measurement equipment are
unbalanced transmission for communication distance, transmission speed, network
capability. The EX952N addressable converter solves the problem and let you easily
build up an RS485 network with your RS232 devices.

  • Page 3 Quick Start  Initial pin & GND: Each EX952N module has a build-in EEPROM to store configuration information such as address, type, baudrate and other information. Sometimes, user may forget the configuration. Therefore, the EX952N have a special mode named "INIT mode" , to help user to resolve the problem.

  • Page 25 19. $AAU Description: Read data from the COM port buffer Any 232 device should obey the rules of request-reply constitution. In other word, 232 devices are passive. If they have not received any commands, they will not send any message out. However, since the active device frequently appear, our controller is designed with a buffer to receive these message in this situation.
  • Page 26 Example: Command: $01U(CrLf) Response: data1(CrLf) Retrieves “data1” from buffer Command: $01U(CrLf) Response: data2 Retrieves another data “data2” from buffer Command: $02U(CrLf) Response: No data is in buffer Warning: (1)Change CrLf mode will corrupt the integrity of unread data in the buffer (2)Repeat this command several times to ensure the buffer is empty.
