ADDER LINK Product Lines We Repair
Our engineers are trained on the full ADDER LINK product range. Below are the major product families we service.
Adder Link ALIF series
IP-based KVM over network switches enabling remote console access across campus or WAN. Common faults include Ethernet port failures, SSL certificate expiration causing connection lockout, and DHCP lease renewal issues in industrial networks with strict firewall rules.
Adder Link X-series
High-density analog KVM switches for legacy equipment control and serial device management. Typical failures involve EDID (Extended Display Identification Data) memory corruption, analog video bandwidth loss causing signal ghosting, and mechanical relay contact wear on hot-switched channels.
Adder Link Infinity series
Fiber optic KVM extenders for long-distance transmission and EMI-sensitive industrial environments. Repair challenges include DVI/HDMI converter chip failures, fiber transceiver alignment issues, and USB hub controller failures on multi-port models.
Adder Link USB Extender modules
Standalone USB signal extension over Ethernet or serial lines for PLC programming and peripheral access. Common issues include USB enumeration timeout, hub power delivery module failures, and protocol compatibility problems with industrial USB devices.
Adder Link ControlCentre Pro
Software-based centralized KVM management platform for multi-switch environments. Faults include database corruption, license key validation failures, and Java runtime memory leaks under heavy load in large Indian manufacturing networks.
Adder Link Secure KVM (SKVM) series
Military-grade secured KVM switches with encryption and air-gap security for banking, defense, and critical infrastructure. Repair requires understanding secure boot sequences, encrypted firmware update procedures, and tamper-evident seal protocols.

All-India Service
Couriered repairs accepted from any city in India. Doorstep pickup available in Vadodara, Mumbai, Pune, Ahmedabad, Surat, Chennai, and more.
Common ADDER LINK Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in ADDER LINK equipment arriving at our workshop.
- ✓EDID memory corruption causing no video output — Repeated power-off cycles, firmware flashing failures, or age-related EEPROM degradation in Adder Link X-series and older ALIF models. EDID data becomes unreadable, and the switch cannot negotiate display resolution with attached monitors.
- ✓USB hub controller failure - devices not detected — Power surge during device hotplug, firmware timeout in USB enumeration routine, or capacitive degradation on the hub controller chip (commonly Microchip or Mentor Graphics chipsets). Results in 'Unknown USB Device' errors on PLC programming and peripheral connections.
- ✓Ethernet port unresponsive on IP-based KVM switches — RJ45 connector mechanical wear, magnetics module failure, or PHY chip saturation from network storms common in Indian industrial networks with inadequate EMI filtering on Ethernet runs.
- ✓Video signal loss or degraded image quality on DVI/HDMI — DVI/HDMI converter IC failure in fiber optic extender models, analog bandwidth loss from degraded video amplifier stages, or clock recovery PLL lock-loss under high-frequency horizontal sync demands in industrial displays.
- ✓SSL certificate expiration blocking remote access on Adder Link ALIF switches — Default factory SSL certificates expire after 10 years; Adder Link devices refuse new connections when certificate validity window closes. Common in Indian plants with long equipment deployment cycles without firmware updates.
- ✓Mechanical relay failure causing channel switching lockup — Contact arc erosion from high-inductive loads or repeated switching cycles; relay coil burnout from over-voltage transients. X-series analog switches with 8+ year service life commonly exhibit contact resistance rise and occasional non-switching conditions.

Frequently Asked Questions — ADDER LINK Repairs
Do you repair Adder Link equipment anywhere in India?+
Yes. Synchronics repairs the entire Adder Link product portfolio — KVM switches (X-series, ALIF, Infinity), USB extenders, fiber optic interface cards, and secure KVM modules. We offer PAN-India door pickup from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Bangalore, and 50+ cities, with all repairs performed at our Vadodara facility. Standard turnaround is 5-7 working days; we offer 24-hour express service for critical downtime situations.
Can Synchronics repair Adder Link fiber optic KVM extender modules with failing transceiver cards?+
Yes. Our engineers specialize in Adder Link Infinity series fiber extenders. We diagnose transceiver laser failures, DVI/HDMI converter chip degradation, and optical signal loss using precision test equipment. We source OEM-matched transceiver modules and validate signal integrity across distance before return. If OEM spares are unavailable, we identify compatible third-party optics and perform full certification testing.
What is the turnaround time for Adder Link EDID and video path repairs?+
Standard EDID EEPROM reprogramming and video amplifier stage repairs are completed in 5-7 working days. Express service (48-72 hours) is available for Indian manufacturing plants with production stoppages. Synchronics maintains a stock of common Adder Link chipsets (video converter ICs, relay modules, USB hub controllers) enabling rapid component replacement and immediate functional testing.
Do you provide firmware updates and certificate renewal for Adder Link ALIF IP KVM switches?+
Yes. Synchronics performs firmware updates, SSL certificate regeneration, and security policy reconfiguration for all Adder Link ALIF models. We extract existing device configuration (user logins, switch settings, IP assignments) before updates and restore them post-upgrade, minimizing downtime. For devices locked by expired certificates, we enter secure firmware recovery mode and reissue valid certificates suitable for Indian industrial networks with strict firewall rules.
Are your Adder Link repairs backed by warranty and functional certification?+
Yes. All Adder Link repairs carry a 12-month parts and labor warranty covering manufacturing defects and component failures unrelated to physical damage. Synchronics provides a detailed test report documenting all signal paths verified, relay contact resistance measured, and USB enumeration validated. For mission-critical applications, we offer extended 24-month warranties and preventive maintenance contracts with quarterly health checks.
How do I send my ADDER LINK unit for repair?+
Pack the unit securely and courier it to our Vadodara workshop. Include a note with the fault description and your contact details. We will log it into our system and WhatsApp you a job number within 24 hours of receipt. Doorstep pickup is available in Vadodara, Ahmedabad, Surat, Mumbai, and Pune.
What is the cost of repairing a ADDER LINK drive or PLC?+
Repair cost depends on the model and the fault. We offer a free diagnosis — once we identify the fault, we provide a fixed quotation before proceeding. Typical repairs cost 20–40% of the new unit price. We will never repair without your approval.
What warranty do you provide on ADDER LINK repairs?+
All repaired units carry a 6-month comprehensive warranty covering the same fault and related issues. If the fault recurs within the warranty period, we repair it free of cost.
Do you provide a no-fix, no-fee guarantee?+
Yes. If we cannot repair your ADDER LINK unit after diagnosis, you pay only the diagnosis fee (₹500–₹1,500 depending on the product). The unit is returned to you at no additional charge.
