Three Coolscopes were installed in NHLS laboratories in Mthatha, East London and Port Elisabeth and connected via LAN allowing remote control of the microscope from any PC on NHLS network (Figure 1). These laboratories are run by only few pathologists, without access to full immunohistochemical studies, which makes final diagnosis difficult.
Due to security measures on NHLS LAN it was not possible to connect to Coolscopes outside LAN. Virtual Private Network Server was installed to allow connection from any PC at any time and from any site. NHLS VPN server uses Secure Socket Level (SSL) technology with security level compared to this used in e-banking or e-commerce (Figure 2). Example of web page with Coolscope interface is seen on Figure 3.
