The identification numbers for the integrated access controllers cannot be entered through a
control station. This safeguard is provided to ensure a reliable connection between a control
station and an integrated access controller. Attempts to change an identification number of a
system remotely will be denied.
8.3.4.2

Network Priorities

All integrated access controllers on the wireless network have equal priorities. Because of this
equality, no Controller can interrupt a remote session between another Controller and a control
station. This is why the control station always initiates all communication on the RITS
network.
8.3.4.3

Intra-Network Communications

Integrated access controllers cannot communicate with each other. Communication on the
network is only between the control station and a single Controller. Since the communications
on the network of integrated access controllers is always initiated by the control station, the
Controller systems cannot communicate with each other. Figure 8-9 shows a diagram of three
RITS units.
PC
The PC associated with integrated access controller #34 can engage any of the two other units
by using "AT" commands from the communications software used. If a local VT-100 is active
at any of the remote locations, the user will be logged off and the master PC will control the
system unit. When the master PC logs off, the local user will be able to log into the unit again.
Connections at all units are done through the DB9 computer port.
