Your serial equipment uses terminal block wiring instead of a DB-9 plug, and you need it talking over fibre 15km down the line. The SCR460SC-4 handles that. RS-232, RS-422, or RS-485 over single-mode fibre to 20km. Terminal block on the copper side, SC fibre on the other. Auto-detects which standard you're running — no config, no DIP switches. Baud rate up to 460.8K, direction control included. Bench it standalone or rack it in a DCR12 Series chassis alongside other converters. All-metal case, EMI-hardened
