Moxa A52 is a general RS-232 to RS-422/485 converters designed for users who need to extend RS-232 transmission distance and increase networking capability. The device is bi-directional that allow one RS-232 port to be converted into an RS-422 or RS-485 port. This is a legacy model. TNS recommends TCC 100 or TCC-80 (port powered). Feel free to contact TNS for a recommendation to your specific application.
To ease 2-wire RS-485 half-duplex control, Automatic Data Direction Control (ADDC) intelligence, which does not requires a baudrate switch setting, is designed into Moxa A52. This feature simplifies user's RS-485 software programming. Your applications can easily manage data transmitting and receiving via the half-duplex RS-485 port without additional code. All RS-422/485 signals provide TVS protection.
Switch and jumper settings
To change the operation mode, please remove the two screws on the top of the converter, open the cover, and then use the array of sliding switches to set the desired mode. DIP switches are used to select the operation mode (RS-422 or RS-485). For RS-485 mode, the control mode (By RTS or ADDC) is also set by DIP switch.
