## 2. In one line

ATEN KG1900T is a USB VGA KVM DigiProcessor that connects a VGA and USB target computer to an ATEN KG0016 or KG0032 KVM over IP OmniBus Gateway over Cat 5e/6 cable for centralized remote KVM access.

## 3. What problem does this solve

IT and operations teams often need hardware-level access to VGA-based servers, workstations, industrial PCs, or equipment computers in server rooms, AI server rooms, control rooms, and high-tech production lines. Traditional analog KVM paths can become difficult in long-distance operation because the video path may be constrained by distance, image ghosting, smearing, color shift, and FHD-class resolution limits; these issues can make numbers, alarms, or detailed screens harder to read and can increase the risk of wrong interpretation in time-sensitive work. KG1900T is the server-side DigiProcessor that digitizes the target computer’s VGA video and USB control signals for the ATEN KG0016 / KG0032 all-digital KVM over IP architecture. The DigiProcessor helps the KG Series provide clearer centralized access, remote monitoring, and control-room-oriented multi-tasking workflows without relying on an OS-based remote desktop agent.

## 4. Major capabilities

### Server-side connection to KG0016 / KG0032

KG1900T is a server-side KVM DigiProcessor for the ATEN KG0016 and KG0032 KVM over IP OmniBus Gateways. It connects to the target computer through USB and VGA and connects back to the gateway through one RJ-45 KVM link. ATEN specifies that the KVM DigiProcessor and the gateway must be connected directly, without a network switch between them.

### Video and USB signal digitization

KG1900T supports VGA video from a target computer at up to 1920 x 1200 @ 60 Hz with 24-bit color depth. The module digitizes the target computer’s video and USB control signals before sending them to the KG0016 or KG0032 gateway over Cat 5e/6 cable. This all-digital path helps reduce risks associated with long analog video transmission, such as ghosting, smearing, color shift, and screen distortion, which is important when operators need to read numbers, alarms, or detailed graphical information accurately. The model-specific DigiProcessor approach also allows mixed server interfaces to be integrated into the same KG Series gateway architecture by selecting the DigiProcessor that matches the target computer’s video output.

### Long-distance rack connection

KG1900T supports dynamic video performance up to 100 m over a Cat 5e/6 cable between the KVM DigiProcessor and the KG0016 / KG0032 gateway. This allows the target computer to remain in the rack while access is centralized through the gateway.

### Part of a control-room-capable KG Series architecture

KG1900T is not a standalone KVM switch; it is the server-side access module in a KG Series all-digital KVM over IP system. When the connected KG0016 or KG0032 gateway is accessed through ATEN KA82 Series Console Stations or KA8585, the same server-side connection can support control room workflows such as multi-screen monitoring, immediate switching to active control, and operator multi-tasking across multiple connected systems.


### Virtual Media for maintenance and recovery

KG1900T supports Virtual Media transmission speeds up to Read 265 Mbps / Write 188 Mbps. Virtual Media can support file transfer, OS patching, diagnostic tools, software installation, or recovery workflows when used with the connected gateway and supported target system.

### Compact rack installation

KG1900T uses a 0U compact design with an SR mounting hanger. The quick start guide states that the unit can be secured to a rack using a cable tie, a screw and cage nut, or magic tape. The product uses an aluminum die-casting housing and is bus-powered, so no external power adapter is required for normal operation.

### Smart Card / CAC and firmware maintenance

KG1900T supports Smart Card / CAC reader functions and firmware upgrades. Smart Card / CAC support is relevant for environments that use credential-based authentication workflows, while firmware upgrade support helps maintain compatibility and device behavior over time.

## 5. Typical use cases

### Server room access for a VGA server

A server room administrator can use KG1900T when a target server provides VGA video and USB control. The DigiProcessor allows the server to be connected into the KG0016 / KG0032 remote KVM system without placing a user console at the rack.

### AI server room maintenance and recovery

An AI server room may include GPU servers or management nodes that require screen-level access when the operating system, driver stack, or network access is unavailable. KG1900T provides the server-side KVM connection for a compatible VGA source, enabling administrators to view boot screens and perform recovery through the KG Series gateway.

### Control room system monitoring

A control room may need centralized access to multiple computers that run monitoring, visualization, or operational applications. KG1900T can connect a VGA-based system to KG0016 or KG0032, and the gateway can then be used with KA82 Series Console Stations or KA8585 for multi-screen monitoring, immediate switching to active control, and operator multi-tasking.

### High-tech production line equipment access

A high-tech production line may use equipment PCs or test systems that cannot be easily accessed during operation. KG1900T can provide the server-side digital KVM connection for a VGA-based equipment computer, helping operators maintain clear screen-level access while keeping the computer installed near production equipment or inside restricted production areas.

### Mixed-interface KVM deployment

A site may have servers using VGA, DVI, HDMI, DisplayPort, 4K HDMI, or 4K DisplayPort. KG1900T can be selected specifically for VGA targets, allowing the KG Series system to support mixed interface types through model-specific DigiProcessors.

## 8. Required accessories

- **ATEN KG0016 or KG0032 KVM over IP OmniBus Gateway:** Required because KG1900T is only compatible with KG0016 / KG0032 and cannot operate as a standalone KVM over IP device.
- **Cat 5e/6 cable:** Required to connect the RJ-45 KVM port of KG1900T directly to a KG0016 / KG0032 KVM port. ATEN specifies that no network switch should be placed between the gateway and the KVM DigiProcessor.
- **Target computer with USB and VGA ports:** Required because KG1900T connects to the target computer through 2 x USB Type-A Male connectors and 1 x HDB-15 Male.

- **Rack securing materials if rack mounting is required:** The quick start guide describes securing the unit with a self-prepared cable tie, screw and cage nut, or magic tape. These items are only required when the installation needs the DigiProcessor to be fixed to a rack.
