Network kit DATACOM 4590 — cable tester, RJ45/RJ12 crimp tool, 8P/6P plug crimper and wire stripper

DATACOM 4590 network kit combines essential handheld tools for creating, terminating and testing Ethernet and telephone cabling. The set includes a cable tester for verifying continuity and pair order, a crimp tool compatible with 8P (RJ45) and 6P (RJ12) modular plugs, and a wire stripper for preparing conductor insulation. Designed for installation, maintenance and fault-finding of LAN, telephone and patch cords, the kit enables efficient cable termination and helps ensure reliable connections in small- to medium-scale network deployments.

Advantages

The kit groups a compact cable tester, a robust crimping tool for both 8P and 6P plugs, and an adjustable wire stripper into a single portable package. The cable tester provides quick verification of conductor continuity and pair sequencing, reducing time spent locating wiring faults. The dual-purpose crimp tool supports RJ45 and RJ12 plugs for Ethernet and telephone terminations, while the stripper offers precise insulation removal without damaging conductor strands. Together they simplify on-site work and reduce the number of separate tools technicians must carry.

Suitable for

• Installation and termination of Ethernet (Cat5e/Cat6) patch cables
• Telephone cable preparation and RJ12 terminations
• On-site testing and verification of cable continuity and pair order
• Maintenance and troubleshooting in offices, server rooms and small data closets

Key specifications

• Cable tester function: checks continuity and pair sequence for multi-conductor network and telephone cables
• Crimp tool compatibility: accepts 8P modular plugs (RJ45) and 6P modular plugs (RJ12)
• Wire stripper: adjustable stripping length for solid and stranded conductors used in network and phone cables
• Tool form factor: handheld, manual operation for field use without external power
• Build characteristics: metal crimping mechanism with molded ergonomic handles

How to use

Prepare the cable by cutting to length and using the wire stripper to remove the outer jacket and individual conductor insulation to the required length. Arrange conductors according to the intended pinout and insert into the modular plug until the conductors reach the end of the plug. Place the plug into the crimp tool and compress firmly to secure the contacts to the conductors. After crimping, connect each end of the finished cable to the cable tester to confirm continuity and correct pair sequencing; follow the tester’s indicator signals to identify any open, shorted or miswired pairs. For telephone cables using 6P plugs, follow the same steps using the RJ12-compatible crimping slot.

Usage recommendations

Use the wire stripper calibration to avoid nicking conductor strands, and ensure plugs are fully seated before crimping. When testing, use the tester’s labels or LEDs to compare both cable ends and repeat tests after any repair. Store the tools clean and dry to maintain crimping accuracy and tester reliability.
