DB9 RS232 Serial to 8pin AV Terminal Block Screw Adapter Converter Block Plug Cable (Male) What this adapter does Converts a male DB9 RS232 serial plug into an 8pin AV terminal block with screw connections. Provides a simple, solder way to break out RS232 signals for custom wiring, quick field changes, or integration with terminalblock driven equipment. Key benefits Saves time: attach or change field wiring quickly using screw terminals instead of soldering or crimping. Reduces errors: individual screw terminals make it easy to identify and secure each conductor. Versatile: enables RS232 devices with a DB9 interface to connect to systems or cabling that use an 8pin terminal block layout. Compact and practical: small footprint fits into tight installations and helps keep wiring tidy. Main features and attributes Connector type: male DB9 RS232 plug on one end; 8position AV terminal block screw adapter on the other. Functionality: breakout/conversion of RS232 signals to discrete screw terminals for direct wiring. Compatibility: works with equipment using standard RS232 (DB9) serial interfaces and with devices or custom harnesses that accept an 8pin terminal block. Build: designed for secure screwtype wire retention and reliable contact for serial communication. Size and installation: compact adapter that plugs into a DB9 serial port; wires are secured into the 8 screw terminals with a small screwdriver. Typical use cases Field wiring and device integration: quickly connect serialcontrolled equipment (e.g., controllers, sensors, legacy instruments) to custom cable runs or building wiring without reterminating DB9 connectors. System installation and testing: use as a breakout for temporary or permanent connections when configuring RS232based devices, debugging serial lines, or mapping signal pins. CCTV, POS, industrial automation: useful where devices provide RS232 on a DB9 and system wiring or accessories use terminal block inputs. How to use Plug the male DB9 directly into the device's DB9 serial port. Strip appropriate wire ends and insert each wire into the corresponding screw terminal on the 8pin block. Tighten each screw to secure the conductor and verify connections against the device's RS232 pinout. Why choose this adapter Practical solution for converting between DB9 RS232 and terminalblock wiring without tools beyond a screwdriver. Keeps installations flexible and serviceable, simplifying maintenance and wiring changes in the field. Note Use with standard RS232 signal levels and wiring conventions. Verify pin assignments on your devices before wiring to ensure correct signal mapping.
