CONEL Product Lines We Repair
Our engineers are trained on the full CONEL product range. Below are the major product families we service.
CONEL Remote Access Gateways
Industrial gateways enabling secure remote monitoring and diagnostics of machinery. Common faults include cellular modem failures, SIM authentication errors, VPN connection drops, and firmware corruption during OTA updates affecting operational visibility.
CONEL Industrial Routers and Switches
Ruggedised Ethernet switches and routers for factory floor networking in harsh environments. Repairs address port failures, VLAN misconfiguration, PoE power delivery faults, and environmental stress from humidity and temperature fluctuations.
CONEL Serial Communication Converters
Devices converting legacy RS-232/RS-485 machine data to Ethernet and 4G for Industry 4.0 integration. Common issues include baud rate synchronisation failures, protocol timeout errors, data corruption in high-noise factory environments.
CONEL Cellular IoT Modules
Embedded cellular connectivity units for machine-to-cloud data transmission in remote plant locations. Repair challenges include signal strength issues, battery charging circuit faults, GPRS/LTE radio failures, and antenna connector degradation.
CONEL Edge Controllers and DIN Rail Units
Compact edge computing devices for local data processing and PLC integration in cramped cabinet spaces. Issues include CPU overheating, SD card slot damage, GPIO pin failures, and watchdog timer resets under heavy processing loads.
CONEL Cellular to Serial Adapters
Cost-effective modules bridging cellular networks with industrial serial equipment lacking native 4G capability. Common repairs involve modem firmware crashes, power supply regulation failures, and serial port signal integrity issues.

Common CONEL Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in CONEL equipment arriving at our workshop.
- ✓CONEL Cellular Modem Not Registering Network — SIM authentication failures, expired data plans, network operator handshake issues, or internal modem flash memory corruption. Indian carriers (Jio, Airtel, Idea) sometimes have compatibility gaps with international CONEL devices due to network protocol variants.
- ✓CONEL Gateway VPN Connection Drops Intermittently — Weak cellular signal in remote plant locations, firewall policy timeouts, MTU size mismatches between factory network and cloud servers, or memory leaks in CONEL firmware versions prior to v2.8.5.
- ✓CONEL Ethernet Switch Ports Not Forwarding Traffic — Spanning tree protocol loops, VLAN configuration errors during factory network integration, PoE power depletion under high-load conditions, or port LED driver IC failures on multi-port units like CMS-400.
- ✓CONEL Serial Converter Data Corruption in High EMI Factory — Inadequate shielding on RS-485 cables, missing surge protection diodes on serial ports, ground loop issues between legacy PLCs and Ethernet network, or baud rate mismatches causing frame errors.
- ✓CONEL Edge Controller CPU Thermal Shutdown — Blocked airflow in cabinet due to poor mounting, failed internal heatsink contact with CPU die, ambient temperatures exceeding 50C in Indian summer conditions, or runaway process consuming 100% CPU cycles.
- ✓CONEL SD Card Slot Reads Old Data After Reboot — Filesystem corruption on SD card, failed write-cache flush circuits, contact corrosion on micro-SD adapter pins, or firmware bug in CONEL file system driver causing stale block caching.

Frequently Asked Questions — CONEL Repairs
Do you repair CONEL equipment anywhere in India?+
Yes, absolutely. Synchronics repairs the full CONEL product range — cellular gateways, industrial routers, serial converters, edge controllers, and IoT modules. We offer PAN India door pickup from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Nagpur, and all major cities. Your equipment comes to our fully equipped facility in Vadodara, Gujarat, where our 180+ engineers diagnose and repair CONEL devices using advanced test benches and carrier-specific network simulators. Typical turnaround is 5-7 working days.
My CONEL gateway lost cellular connection. Can you fix it without an RMA to Europe?+
Yes. Most CONEL cellular failures — modem firmware corruption, SIM authentication errors, antenna connector issues, power supply problems — can be repaired in-house at Synchronics without warranty claim delays. We stock replacement modem modules, SIM interface circuits, and power regulators. We reprogram firmware directly via serial port, test with Indian telecom carriers (Jio, Airtel, Idea, VI), and validate connectivity before returning your unit. Same-day modem swaps are possible for stock failures.
What is your experience with CONEL CMS and CRS series switches?+
Synchronics has repaired 100+ CONEL industrial switches (CMS-200, CMS-400, CRS-2020 models) used in Indian textile, automotive, and process plants. Common repairs include port failures, VLAN misconfiguration after network redesigns, PoE circuit faults under high load, and environmental damage from factory humidity. We have spare Ethernet port controller ICs, managed switch firmware images, and can restore custom VLAN configurations from your network documentation. We also perform port isolation and loopback testing to verify repair completeness.
Can CONEL gateways work reliably with Indian 4G networks from different carriers?+
Yes, but with proper configuration. CONEL devices support 2G, 3G, and 4G standards, but success depends on correct APN settings, SIM compatibility, and antenna placement in your factory location. Synchronics has tested CONEL gateways with Jio (Vodafone Idea 4G LTE), Airtel, and Idea networks across multiple Indian regions. We maintain carrier-specific APN profiles, provide antenna upgrade recommendations for weak-signal sites, and conduct multi-day connectivity tests before handover. We also advise on SIM plans optimised for industrial IoT (unlimited data, static IPs where available).
My CONEL edge controller keeps rebooting in our hot summer climate. What is wrong?+
Thermal shutdown is very common in Indian manufacturing environments where ambient temperature exceeds 50C. CONEL edge controllers (CIC-2100, CIC-2200 models) have built-in thermal protection that forces restart if CPU junction temperature exceeds 85C. Synchronics diagnoses root cause: blocked cabinet airflow, failed heatsink contact, or runaway CPU tasks. We clean heatsinks, reapply thermal compound, add exterior cooling fans or cabinet heat exchangers, and profile your running processes. We also upgrade your unit with thermal paste rated for industrial -40 to +85C operation, test under sustained load, and provide cabinet layout recommendations to prevent future thermal issues.
How do I send my CONEL 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 CONEL 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 CONEL 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 CONEL 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.
