Small passive RS232 to RS422 converter with DB9 female and screw terminal block

SMUGDESK

SMUGDESK RS232 to RS422 Data Converter Bidirectional FDX Full Duplex Passive DB9 to Terminal Block

SKU CH-2XCB-6KKR4

Passive RS232 to RS422 converter draws port power for full-duplex bidirectional communication up to 115.2Kbps with terminal-block wiring

  • Passive power from RS232 port eliminates external adapter
  • Full-duplex bidirectional conversion enables simultaneous transmit and receive
  • Wide device compatibility suits PLC, CNC, HMI and servo systems
  • Up to 115.2Kbps with differential signalling for long-distance noise immunity
  • Plug-and-play DB9 to terminal block requires no driver installation

Passive RS232 to RS422 converter

This passive adapter converts signals between an RS232 port and an RS422 interface without an external power supply. It draws operating power directly from the host RS232 serial connection. The unit supports true full duplex FDX operation for simultaneous transmit and receive.

Installers wiring PLC, CNC, HMI or servo gear

The DB9 female connector plugs into the host while the screw terminal block simplifies field wiring for industrial devices. No driver installation is required for immediate use. Buyers needing multipoint networks or galvanic isolation should look at other converter types.

115.2 Kbps maximum baud rate

The converter handles serial speeds from 300 bps up to 115.2 Kbps over RS422 differential lines. This differential signalling resists electromagnetic interference for reliable long distance runs. The exact distance achieved depends on cable quality and site conditions.

Questions about this item

What RS232 port must I already have on my host device to power and connect this converter?

You need a standard DB9 female RS232 serial port on the host; the converter draws its operating power directly from that port and requires no external supply.

Will this 422232 adapter work with my existing PLC, CNC or HMI that uses RS422 wiring?

Yes, it provides true FDX fullduplex bidirectional conversion between RS232 and RS422, compatible with PLC, CNC, HMI, servo controllers and similar industrial serial devices.

How can I verify the link is operating at up to 115.2Kbps after wiring the terminal block?

Confirm both ends are set to the same baud rate up to 115.2Kbps, then send test data; successful simultaneous transmit and receive indicates the fullduplex link is working.
