TLC422
TLC422 Series RS-232 to RS-422 Converter
The 3onedata TLC422 series provides bidirectional conversion between one RS-232 port and one RS-422 port without an external supply. The official series covers TLC422/9 with DB9 interfaces and a 5-pin RS-422 terminal block, and TLC422/25 with DB25 connectors. Published limits include 0–115200 bps, up to 1,200 m on RS-422, 15 kV electrostatic protection, and -20 to +60 °C operation. Exact variant is confirmed at RFQ.

Frequently asked
What is the difference between TLC422/9 and TLC422/25?
TLC422/9 uses a female DB9 connector for RS-232 and a DB9 RS-422 interface equipped with a 5-pin terminal block; its published size is 90 × 33 × 16.5 mm including the terminal block. TLC422/25 uses female DB25 for RS-232 and male DB25 for RS-422, with a published size of 65 × 55 × 16.5 mm.
Does the TLC422 series need an external power supply?
No external supply is listed. The TLC422 series obtains power from the host RS-232 TXD, RTS and DTR signal lines. Host-port electrical behavior and the exact /9 or /25 connector version remain subject to engineering review.
What baud rate and transmission distance does TLC422 support?
The official datasheet lists 0–115200 bps, up to 15 m on the RS-232 side and up to 1,200 m on the RS-422 side. Actual reach depends on the cable, grounding, topology, baud rate and noise environment.

What we check
We check the ports, topology, protocol map, timing and management needs before selecting the TLC422.
TLC422/9 and TLC422/25 use different connectors and enclosure footprints
the exact variant is confirmed at RFQ
TLC422/9 is 90 × 33 × 16.5 mm with the terminal block, while TLC422/25 is 65 × 55 × 16.5 mm
Power is taken from the host RS-232 TXD, RTS and DTR signals, so the host serial-port electrical behavior must be reviewed
The published 0–115200 bps and 1,200 m RS-422 figures depend on the full cable, grounding and noise environment
The official datasheet does not state galvanic isolation, so isolation must not be assumed
Application fit is subject to engineering review
