access:

Stand-alone controllers that are directly connected to the PC via a cable.Controllers within a network.Either stand-alone or networked controllers via GSM or landline modem.Devices with IP addresses, via Ethernet.

Remote Access can be used with either Vision or M90/91 controllers. Vision controllersrequire O/S versions 2.96 and higher; M90/91 require V3.00 and higher.
