The PCoIPTM technology is designed to deliver a user’s desktop from a centralized host PC or server with an immaculate, uncompromised end user experience across standard IP networks – including full quad or dual DVI monitor video, complete USB compatibility, and full-duplex high-definition audio. The new ALLNET ZC-2321P PCoIP zero client is a portal device (5.906 x 5.118 x 1.772 inches) based on the proprietary Teradici® TERA2321 Portal processor that resides in a remote client access device.

The PCoIP Host/Client system separates the user from the PC or workstation, which provides both increased security and needs minimal IT administration and support overhead for the enterprise while giving end users complete remote display and I/O functionality for personal computer (PC) or workstation graphics user interfaces. The system includes a PCoIP Software Agent or PCoIP Host Processor at the host Virtual Machine or PC/Workstation that encodes the display, USB and audio signals before transmitting them over an IP network. The PCoIP Zero Client at the remote site receives and decodes these signals, creating standard PC interfaces for the display, USB peripherals and PC audio. The PCoIP system also supports a reverse communication path for items like USB keyboards, mouse, microphone audio and other peripherals. It is connected to the network via standard Ethernet using RJ45 at 10/100/1000Mbps.

The second-generation PCoIP Host/Client system provides the following benefits:

  • Wide range of applications from very robust personal workstations to simple kiosks
  • Support for up to four 1920×1200 high-resolution, perception-free DVI video outputs and USB 2.0 peripherals allows PC or workstation relocation to the datacenter or computer room without compromising end user experience or productivity
  • High cost effectiveness when integrated into PCs or workstations
  • Robust PC experience delivered to the end user without the need for Terminal Services protocols
  • Performance using existing enterprise networks, enabling low cost, straightforward kiosk or digital signage functionality.

The ALLNET ZC-2321 PCoIP zero client ships with two 2Gbit of DDR3 memory and supports two DVI, four USB, a Speaker, a Microphone, a Headphone and a RJ45 Ethernet connectors. Output is driven by the DVI ports for video and USB 2.0 ports for peripheral and I/O connections. The ALLNET ZC-2321 PoE zero client features Power-over-Ethernet (PoE) which allows a single cable to provide both Ethernet connection and electrical power to the device. The net result is a fan-less and reliable client-side device that requires minimal IT administration and support since all processing resides on the host PC orworkstation.

This client device is compatible with TERA22xx and TERA1202 host cards, and VMware® ViewTM 4.5 or later.
