Hardware and Technical Requirements
New computers are much faster than old, and where possible it is always preferable to use new commercial computers. we recommend our clients to be wary of backstreet “custom build” machines which are often made from cheap parts and can be prone to breakdown, especially if running a very intensive database application for 10 hours per day. computers aimed at the home market should be avoided also, as these are built significantly less robust than commercial pc’s.
This part of the document lists our minimum and recommended (29/08/08)machine specifications.

NOTES: The options for server software and workstation software outside of the Microsoft Suite are very much available, but not supported or endorsed by Houston Medical. This is in no way a reflection upon alternative systems, and data servers build with Linux have a very strong network system, with both advantages and disadvantages over the Microsoft products. VIP was programmed using the Microsoft suite of languages and intended to run on Microsoft based operating systems. While the program may operate quite happily outside of these boundaries, you do so at your own discretion.

With terminal server and thin client, the speed of the workstations does not matter. In this manner any machine capable of running the Remote Desktop client can connect to a terminal server. In real practice, to generate the required screen draws without lag, terminals of 1000mhz + have proved best.
When designing a system for terminal server, the network engineer needs consider primarily how much ram will be needed.
With any server, reserve minimum 512mb for the server and console services only. Then add about 100mb per user after that. If the clients are going to run any other applications such as email clients, office apps, and internet browsing then the ram per user will increase accordingly.
A simple table can plan the ram requirements:
Server 512mb
15 users @ 100mb ea 1500mb
TOTAL RAM required 2GB minimum
So to be on the safe side, put 4.0gb of ram in the terminal server, which is the maximum for Server Standard edition.
If you would like assistance installing VIP onto a system, please download the document:”VIP Installation Guide” from our website, which outlines the complete installation procedure on single user, peer-to-peer network, client/server and thin-client networks.
Third party products:
VIP works with a number of external hardware devices, such as Eye Machines, ECG Machines, ETT Machines and scanners. Not all devices are supported, and it is very imported to check and confirm that any device is compatible.
Scanners
VIP will work with any scanner which is TWAIN compliant. As far as models go, it is best to decide depending on volume of scanned material. For example, if you only intend to scan a few documents a week, then a cheap flatbed model would be fine. If you were scanning in excess of a dozen or so a day, then a multi-page-feed scanner would be ideal, but expensive.
The other option is multifunction printers - many new printers these days are scanners, copiers, printers and fax machines all built into one. VIP has been tested and works on network device scanners such as photocopiers as well.
VIP has support for individual document scanning direct into the individual patient file, bulk-scanning through document feeders, and the ability to scan / import images into clinical notes.
Digital Cameras
VIP has the functionality to import images from any location on the PC or network. Most digital cameras save their files as .jpg images, which VIP can import into Clinical Images.
Eye Machines
There are a large number of specialist eye-machines which we have developed interfaces for, including machines from TopCon, Humphrey and others.
ECG Machines
VIP does not have a direct interface with any ECG machines, however a number of our clients are exporting the ECG from their generic ECG software, and then importing that as part of the VIP imaging software in Clinical Notes.
