TB61_PC-
100 for AxiomV™
Virtual IOC Emulator
With firmware version VIOC8 the PC-100 is used to emulate IOC-16 controllers.
One PC-100 can emulate from one to sixteen IOC-16 panels. Some alarm
panels (the host) can use this version as a general means to interface with the
Axiom system.
The emulated IOC16s act as inputs to the network and will present the various
states and configurations that a normal IOC16 would do. If configured as an
input, commands sent through the host channel will generate messages into the
Axiom system. If configured as an output, output control messages will be sent
to the host from the Axiom system. A simple protocol has been designed that
allows foreign vendors an opportunity to interface to the Axiom Access Control
System by messages to the RS232 or RS485 port on the PC100.
DIP-Switch Settings
The Axiom Access Control System starts its IOC addresses at address 5 and can
support up to sixteen devices ending at address 20. To make the DIP-switches
capable of selecting the range of addresses to which the emulator will respond,
an offset address scheme has been developed. The first four switches create
the start offset and the last four switches create the end offset.
Desired
Address = DIP a 5
. The device when polled will answer any address
that falls between the desired start and end addresses (inclusive). If the end
address is smaller than (or equal to) the start address only the start address will
be used.
