Description and Operation
1.1
Product Purpose
RS-FX-MM / RS-FX-SM40 Serial RS-232 / RS-422 / RS-485 Fiber Optic Modem (hereinafter
referred to as the modem) is designed to convert a standard RS232 / RS485 / RS422 signal to a fiber
optic link to extend the signal up to 40 Km.
The modem provides transmission distance up to 40 Km for signals from Orion ISS
intrusion / fire alarm and detection equipment and other equipment that use RS-232, RS-422, RS-485
interfaces.
An
RS-FX-MM
modem is designed to be used with
multi-mode
optical fiber to extend signals
up to
2 Km
. For communicating data,
two fibers
are used: one fiber for receiving signals and the
other one for transmitting signals.
An
RS-FX-SM40
is designed to be used with
single-mode
optical fiber to extend signals up to
40 K
м
. For communicating data,
two fibers
are used: one fiber for receiving and the other one for
transmitting signals.
Scope of application: intrusion / fire alarm and detection systems, access control systems,
building automation systems.
The modem is intended for round-the-clock operation.
The modem is classed as non-repairable and periodically serviced equipment.
