For a system with from 17 to 64 Access Points, you must have
one* 4230 (or 4235) Comms module set to type F and
continuously connected via a Comms Driver to any computer
on your local area network.
•
For a system with more than 64 Access Points, you must have
one* 4235 Comms module set to type F and continuously
connected via a Comms Driver to any computer on your local
area network.
*Note that if you have more than one Hardware System, all the
Comms modules on these extra Hardware Systems (Local or Remote
Site) can be 4232 Comms modules.
On a system which requires more than one Comms module,
addressable 4232 Comms modules handle all the messages on each
communications branch. The following diagram shows a Local
Hardware System where the Comms module connected to the
computer is set to type F, and the Comms modules downstream from
it each have unique addresses from 0 to 9.

One or two Controller system
A Local Hardware System with one or two 4101-2 Controllers needs
no Comms modules at all - the computer can talk via its Comms
Driver direct to the Controller (or the master Controller if there are
two). Any Local Hardware System with more than two Controllers
requires at least one Comms module set to type F to pass messages
between the computer and the Controllers.
You can have several Local Hardware Systems, each with one or two
Controllers, but if the total number of Access Points is more than 16,
you need one 4230 Comms module set to type F at the head of one of
the Local Hardware Systems.
