NEXCOM MCS transport computers and systems

Define the role of the transport system

NEXCOM Mobile Computing Solutions covers computers and peripherals for road vehicles, rail transport, warehouses and ports. Describe what the system does: gather telemetry, connect onboard devices, process images, show operator instructions or distribute passenger information.

List the data sources, installation locations and equipment involved. For a new installation, include the working cycle, number of vehicles and applications.

For an existing system, provide its designation, an overall photograph and component list. Put the computer, display, switch and power module on separate lines with quantities. Identify the equipment retained at the site and the items being purchased, so the proposal represents the actual system.

Record the complete model and configuration

Copy the entire designation from the identification label, including all letters and digits after the number. Suffixes distinguish VTC and nROK versions; nROK 1040-A and nROK 1040-AC2 illustrate why the short number is insufficient.

Photograph the label, front and rear panels, connectors and bracket. Record the processor, memory, storage and expansion modules when available in the equipment records.

For a replacement, include connected devices and software versions. Identify modules added after the original installation. State quantity, purchasing purpose and vehicle or workstation reference. Use separate label photographs for similar enclosures.

The installed configuration and interfaces guide selection, while previous purchasing records provide supporting identification.

Power, ignition and system shutdown

An onboard computer forms part of the vehicle's electrical installation. State the nominal supply, connection point, protective devices and switching arrangement. VTC and nROK systems use ignition signals in their startup and shutdown logic.

Describe post-stop recording and the time required for application shutdown. Include the supply arrangement for displays, cameras and networking equipment.

Record the designation and connections of any VTK-62B, VTK-SCAP or other backup-power module. Provide the existing circuit diagram and photographs of labelled terminals. List each device's electrical load separately.

This allows the specification to match the computer, peripherals, cables and the operating sequence used on the vehicle.

Telemetry, positioning and mobile connectivity

List the data required by the telematics application: vehicle position, onboard measurements, operator messages or camera images. NEXCOM lists CAN FD, GNSS and SIM positions for nROK 1040-A/-AC2; the application determines the functions used.

Record each source interface and data collection interval. For positioning, identify the antenna location and cable route. For mobile communications, describe the network and connection arrangement.

Treat the communication module, SIM, antenna and computer as individual configuration items. Supply the installed WWAN and WLAN module markings and connector photographs. Describe the platform receiving data at the control centre.

Separate shared configurations from vehicle-specific installations when documenting the telemetry workflow.

Select Edge AI around the processing workload

ATC and aROK transport platforms process data close to cameras and other sources. Begin with the application: the events detected, number of streams, image resolution and frame rate. Record the camera models and connection method.

Then specify the software stack, algorithm format and accelerator requirement. The ATC catalogue includes NVIDIA Jetson platforms, while aROK includes systems using discrete graphics.

List the software and storage tasks: recording, storing results or booting. For a replacement, include the existing configuration and driver versions. Add available space, cooling conditions and supply.

Compare alternatives using the same workload and a complete list of accelerators, memory, storage and peripherals.

Configure the operator station with VMC or VMD

VMC combines the computer and screen in one enclosure. VMD is a separate display connected to an onboard computer. Start with the operator's workflow: displayed information, command input and location of controls and peripherals. Specify screen size, mounting location and available dimensions.

For warehouse vehicles, include photographs of the cab, bracket and cable exits.

Describe workplace lighting, glove use and screen position. A VMD request needs the computer's video output and the display supply; VMC selection needs scanner, network and other peripheral interfaces. Include mounting dimensions and connector markings for a replacement.

List the device, bracket, connections and peripherals together to define the actual workstation.

Match railway equipment to the project

For a railway installation, describe the location on the rolling stock, cabinet arrangement, electrical supply and project requirements. The nROK catalogue covers railway computers, with rROK and aROK providing additional platforms for particular workloads.

NEXCOM lists EN 50155 Class OT4 on the nROK 1040-A/-AC2 product page. Associate requested documents with the precise designation in the purchasing specification.

Use the existing drawings to record connectors, supply, grounding and cable routes. For cameras, state stream count and PoE consumption; AC2 has its own published PoE arrangement. Add mounting and service-access drawings.

Include applications, network configuration and startup settings so the replacement fits the complete project.

Map networking, video and add-on modules

Map the computer, cameras, displays and external connection for VES. Label each port with its device and PoE demand. VES 31-4S/8S and VES 31-4SR/8SR represent vehicle and railway versions; retain complete codes in the equipment schedule.

For VIP passenger video, identify transmitters, receivers, HDMI sources and display points separately.

List add-on modules by function. For example, VTK-PA22-01 adds two Line-out and two Mic-in channels through a miniPCIe module using USB 2.0. For GPS, Ethernet, UPS or converter modules, provide both the module code and host computer model.

Assign cables, antennas and connectors to their devices, making interfaces and mounting locations clear.

Describe the installation and software environment

Identify each item's location: passenger area, driver's cab, exterior installation, cabinet or warehouse station. Describe temperature, dust, moisture, vibration and service space. Record mounting method, cable direction and clearance around the enclosure.

The MCS portfolio includes different protected configurations; retain the selected device version and the site's requirements in the specification.

A software schedule includes the operating system, application, camera and communication drivers, startup configuration and network settings. State who performs configuration and installation checks. Describe storage and backup-power roles where used.

A complete enquiry links environmental conditions, hardware interfaces and software, helping select equipment for the transport architecture already in service.

Create a verifiable procurement schedule

Create an equipment schedule with designation, full code, quantity, purpose and documents. Attach label photographs, a power diagram, network map and installation drawing. Start a new project with the application tasks; start a repair enquiry with the installed configuration and observed fault.

Identify complete computers, separate displays, individual modules and systems for multiple vehicles.

Review proposals line by line: processor platform, memory, storage, connectivity, supply, cables, mounting and software scope. Compare options against one requirements schedule. After delivery, match labels and contents to the agreed list.

On the vehicle, check startup, shutdown, peripheral interfaces, communications and the application in a defined sequence.
