ELO Touch E959434 Serial 3.5MM to DB9 Cable

Overview

The ELO Touch E959434 is a serial adapter cable that bridges 3.5mm mini-jack connectors to DB9 serial ports. This cable solves the connector mismatch problem when integrating legacy serial devices—door readers, access control panels, temperature sensors, or older peripheral hardware—into systems that use standard 9-pin serial connections. The E959434 is purpose-built for surveillance and access control installations where equipment generations don't align on connector standards.

Compatibility

The E959434 works with any ELO Touch system or third-party equipment that has a 3.5mm serial output and requires connection to a DB9 serial input port. Confirm your device's pinout before ordering—serial signal voltage and pin assignment vary across manufacturers. This cable carries signal only; it does not provide power or level conversion. If your source device outputs RS-232 levels and your target input expects RS-232, the cable passes the signal through without modification. Verify compatibility with your system's documentation or contact pre-sales engineering before installation.

Installation Notes

Route the cable away from AC power lines and high-frequency RF sources to minimize induced noise on the serial line. Coiled or bundled serial cables in tight runs can pick up EMI and corrupt data frames. Keep runs under 50 feet when possible—longer distances degrade signal integrity without buffering. If your installation requires cable runs longer than 50 feet, insert a RS-232 line driver or repeater between the E959434 and the target serial device. Secure the connectors with strain relief to prevent intermittent contact from flexing.
