Premier Cable PCM-MP-0088 is a USB-C Multiport Panel Mount Dock developed for office desks, industrial consoles, wall systems, smart furniture and multimedia cabinets.
Unlike a conventional portable USB-C hub placed on a desk, PCM-MP-0088 is designed for fixed panel installation. The host computer can remain inside or behind the equipment while frequently used interfaces are extended to an accessible front-panel location.
Through a single upstream USB-C connection, the module provides USB-A, USB-C, RJ45 Ethernet, HDMI, DisplayPort and 3.5mm stereo audio for integrated data, display, network, audio and peripheral connectivity.

Core Superiority
This product completely revolutionizes traditional desk cable management. Complex systems that previously required multiple adapters can now be elegantly extended to the front panel via a single USB-C cable. This highly integrated design drastically reduces physical clutter and eliminates signal attenuation caused by multi-stage adapters.
Stable Connectivity
The multimedia panel cable pass-through box features independent shielding and isolation for each signal path internally. Equipped with built-in EMI and ESD protection circuitry, it ensures flash-free HDMI 4K video and zero packet loss on Gigabit Ethernet, even in electromagnetic-heavy industrial CNC environments. The high-end network and video chipsets utilize independent power rail architectures, preventing cross-talk and ensuring rock-solid performance during full-load multi-port operations.
Installation Requirements
This design fully accommodates embedded installation requirements across diverse scenarios. The panel edges feature user-friendly, micro-arc bezels that perfectly conceal cutting flaws. Whether installed in wooden desks, metal cabinets, or aluminum CNC panels, it can be easily secured with standard cutout dimensions. The ultra-slim rear cable exit design ensures flexible routing within narrow wall cavities or densely packed multimedia racks.

Frequently Asked Questions
Q1: Can the USB-C port on this panel be used to connect an external monitor?
A1: No. The USB 3.1 Type-C port on this panel is strictly dedicated to high-speed data transmission (10Gbps) and power delivery (5V/3A) with no video Alt-mode functionality. For display output, please use the integrated HDMI or Displayport interfaces directly.
Q2: Can the HDMI and Displayport interfaces output different screens simultaneously?
A2: This depends on whether the USB-C source port of your host device (e.g., laptop or PC) supports the MST (Multi-Stream Transport) protocol. It allows extended screens on MST-supported systems, whereas on SST-only systems (like macOS), it will mirror the displays.
Q3: Will there be flickering or drops on the network/video ports under high electrical interference on CNC machines?
A3: No. The internal cables feature multi-layer aluminum foil and high-density metal braided shielding. Coupled with industrial-grade anti-EMI circuitry, it effectively blocks stray interference in high-electromagnetic industrial environments, guaranteeing rock-solid connections.
Q4: Does this panel pass-through box require an external power supply to work?
A4: This product is bus-powered and does not require an external power supply. It extends the host device's power, delivering up to 5V/0.9A via the USB-A port and 5V/3A via the USB-C port, which is fully sufficient to drive flash drives, portable HDDs, and mice.
