Serial Cable Datalogic 90A052138 Black 4.5 m RS-232

The Datalogic 90A052138 Black 4.5 m RS-232 serial cable is a shielded communication lead designed for reliable serial data transfer between devices that use the RS-232 standard. With a 4.5-metre length and robust black jacket, this cable is intended for use in industrial and commercial environments where stable, low-latency serial connections are required. It fits standard RS-232 ports and is compatible with a range of Datalogic equipment that accepts serial communication.

Advantages

This RS-232 cable provides stable signal transmission over extended length without requiring active signal boosters. The durable outer sheath resists abrasion and mechanical stress typical in busy work areas. Shielding reduces interference from nearby electrical equipment, improving communication reliability. The cable’s length offers flexibility in equipment placement while keeping connections tidy and accessible.

Suitable for

• Connecting Datalogic barcode scanners and mobile terminals to PCs or serial printers
• Linking industrial controllers, label printers, and legacy serial devices
• Data logging and serial communication in warehouses, retail points of sale, and manufacturing
• Field service setups where a longer, durable RS-232 cable is required

Key specifications

• Connector type: RS-232 standard connectors for serial communication
• Length: 4.5 metres
• Color: black outer jacket
• Cable construction: shielded to reduce electromagnetic interference
• Intended environment: industrial and commercial use with abrasion-resistant jacket

How to use

Identify the RS-232 ports on the devices to be connected and align the cable connectors accordingly. Insert the connectors firmly into the serial ports and secure any retention screws or clips if present to ensure a stable physical connection. Power on both devices and configure the serial communication parameters (baud rate, parity, data bits, stop bits, flow control) in each device or software application to match. Verify the connection by sending a test data transfer or using device diagnostics.

Recommendations

Avoid routing the cable parallel to high-voltage power lines for long distances to minimize interference. In environments with strong electromagnetic sources, use grounded connectors and ensure both connected devices share a common ground. For permanent installations, secure the cable with appropriate clamps and allow service loops to prevent strain on connectors.
