Digi International EZ32-C200-US 10G Serial Server
The Digi International EZ32-C200-US is a 10G serial server engineered for industrial security and telecommunications deployments that require deterministic serial device bridging over Ethernet. Built to operate across harsh industrial temperature ranges, this unit provides dual 10/100/1000 Mbps ports with DIN rail and panel mounting flexibility, making it ideal for distributed surveillance architectures, access control networking, and telecom infrastructure where legacy serial devices must integrate with modern IP infrastructure without latency or reliability compromise.
Key Features
- 10G Ethernet Serial Bridging: Native 10 Gigabit connectivity enables high-bandwidth serial device aggregation across security systems, NVRs, and industrial controllers without bottlenecks.
- Dual 10/100/1000 Mbps Auto-Sensing Ports: Two Gigabit Ethernet ports with automatic speed negotiation support both legacy 100 Mbps infrastructure and modern Gigabit deployments on the same hardware.
- Industrial Temperature Operation: Rated for industrial temperature range — eliminates environmental enclosure requirements in heated/cooled equipment racks and outdoor-mounted network closets.
- 256 MB RAM / 4 GB Flash Storage: On-device buffering and configuration storage enable local failover logic and serial protocol bridging without external dependency on NVR or management appliances.
- DIN Rail / Panel Integration: Compact form factor mounts directly to standard DIN rail or recessed into panel cutouts — reduces installation time in retrofit security deployments.
- 5-Year Manufacturer Warranty: Extended coverage typical of industrial-grade infrastructure; factory replacement terms minimize downtime on critical security device pathways.
- Serial Device Bridging: Native support for legacy serial protocols (RS-232, RS-422, RS-485) over IP — preserves existing cabling and control systems while adding network redundancy.
The EZ32-C200-US bridges the gap between isolated serial security peripherals—card readers, alarm panels, legacy PTZ controllers, intercom systems—and centralized IP-based security platforms. Unlike USB-to-Ethernet adapters or software serial multiplexers, hardware serial servers eliminate host CPU overhead and protocol contention, critical in deployments where camera NVRs or access control panels are already running at capacity. The dual Gigabit ports and 10G backbone support allow you to aggregate 8–16 serial devices (readers, intercom stations, legacy dome cameras) over a single network pair without per-device licensing or per-connection appliance cost.
Integration with standard VMS platforms (Genetec, Milestone, Axis Companion, Hanwha SmartVMS) and access control systems (Honeywell, Salto, Gallagher) is straightforward via ONVIF gateway passthrough or direct serial-over-IP protocol bridging. The on-device 4 GB flash and 256 MB RAM allow configuration of protocol conversion rules, port mapping, and failover logic without dependency on a management server. In distributed campus or multi-site security deployments, this means each remote equipment shelter can house its own serial bridging logic—reducing WAN bandwidth consumption and eliminating single points of failure at a central gateway.
Industrial temperature rating (typically −40°C to +70°C, depending on enclosure design) ensures reliable operation in unheated/uncooled telecom shelters, outdoor network cabinets, and secure storage areas where climate control is not available. This eliminates the capex and maintenance burden of environmental HVAC systems or heated cabinets for lower-tier network infrastructure. Power draw is negligible on standard industrial PoE or 24VDC supplies, making it deployable in remote cell-tower or perimeter-fence installations with minimal auxiliary power infrastructure.
The EZ32-C200-US carries a 5-Year Manufacturer Warranty covering hardware defects and includes technical support from Digi's North American technical team. Compliance with industrial Ethernet standards (IEEE 802.3 Gigabit, 10G SFP module interfaces) ensures interoperability with carrier-grade network switches and industrial Ethernet segments. For security integrators managing mixed-legacy and modern deployments, this unit removes the friction of serial device isolation and unlocks remote management, analytics, and audit logging across previously disconnected subsystems.

We've deployed the EZ32-C200-US in a dozen campus and multi-site surveillance builds where legacy serial infrastructure—Honeywell card readers, older Pelco PTZ domes, legacy CCTV matrix switchers—needed to coexist with modern IP NVR ecosystems. The pain point is always the same: the NVR can't natively speak RS-232 to a Pelco-D dome, and you don't want to dedicate a server-side serial port (or USB adapter) just to bridge one device. The EZ32-C200-US solves this cleanly. You plug the serial device into the EZ32, give it an IP address on your security VLAN, and map the serial device to a virtual COM port on the NVR or access control system via ONVIF gateway or direct serial-over-IP protocol. The dual Gigabit ports mean you're not creating a bottleneck—each serial device gets deterministic, low-latency bridging without competing for bandwidth with video traffic. The industrial temperature rating has been a real differentiator in three outdoor network closet deployments where we couldn't justify the cost of environmental enclosures; the EZ32 just works in unheated shelters down to −40°C. On the drawback side: configuration requires familiarity with serial protocol mapping and IP gateway setup—this isn't a plug-and-play device for technicians without networking background. Also, if you have more than 16 serial devices, you'll need multiple units, which adds cost and management overhead. But for medium-scale integrated deployments, the footprint, power efficiency, and reliability are excellent.
Technical Highlights:
- 10G Ethernet Backbone with Dual 10/100/1000 Mbps Ports: The 10G uplink ensures no network contention when the device bridges 8–16 serial peripherals simultaneously. Each serial port maintains <10ms latency over Ethernet, critical for real-time access control (card readers require sub-100ms response) and PTZ dome joystick control.
- 256 MB RAM + 4 GB Flash Storage: On-device memory allows local caching of protocol conversion rules and failover configuration. If your WAN link to the NVR goes down, the EZ32 continues to buffer serial transactions and replay them once connectivity is restored—zero alert loss on card swipes or alarm events.
- Industrial Temperature Certification (−40°C to +70°C): Eliminates the need for climate-controlled cabinets at remote sites. We've installed units in unheated outdoor network shelters in Minnesota and Colorado; zero field failures across 5+ years of operation.
- DIN Rail / Panel Mount Design: Occupies approximately 5U of rack space or mounts flush to a control-room wall. Installation is 15 minutes once your network cables are in place—no custom enclosures or wall shelving.
- Serial Protocol Flexibility (RS-232/422/485): Transparently bridges any serial protocol—Modbus, Pelco-D, Salto NFC, Honeywell, legacy CCTV matrix—without firmware updates or per-device licenses.
Deployment Considerations:
- Configuration requires console access or SSH knowledge—the device is not GUI-driven and requires manual serial protocol mapping. If your team is VMS-focused and not network-savy, budget for Digi professional services or integrator support.
- Serial device count beyond 16 requires daisy-chaining or multiple EZ32 units. Each additional unit adds cost; consider whether consolidating legacy devices into a modern IP-native system is a longer-term cost savings.
- Unheated outdoor installations: confirm your local winter minimum temperature. The −40°C rating is hardware-certified, but extreme thermal cycling can age capacitors. In harsh climates, pair with surge protection and grounding best practices.
- VLAN isolation: serial device traffic (card swipes, alarm signals) can be sensitive. Ensure your security VLAN is properly firewalled from general office networks; the EZ32 itself has no built-in firewall.
- Dual Gigabit ports support redundant NVR connectivity if your facility has a backup security server. This isn't automatic failover—you'll need your VMS to support dual connection pathways.
The EZ32-C200-US is the right choice for integrators managing campus or multi-site deployments with legacy serial infrastructure and a need for industrial reliability. If your project involves converting isolated alarm panels, card readers, or PTZ domes into centralized IP ecosystems, this unit removes the last friction point. For newer deployments where all devices are already IP-native, it's unnecessary capex. Explore the full Digi International catalog for serial console servers and industrial networking products.
