Connecting the Optical Fiber
The Fiber Optical link architecture supports PTP and SFR
mode for different purposes.
1. PTP Mode (Peer to Peer)
The PTP (Peer to Peer) mode provides connection between
2 nodes. When working on this mode, JetCon 2401 can
transmit data and receive it at same time, which means
JetCon 2401 is working at full duplex mode.
2. SFR Mode (Serial Fiber Ring)
To extend the transmission distance and to save
the fiber cable cost, JetCon 2401can link to each
other as a ring architecture, in this mode JetCon
2401 only provides half duplex transmission and
all of data communication is controlled by the
host device. The maximum of communication
nodes can up to 20.

Note: To ensure your fiber converter transmission/receiving of data between the 2
nodes, the attenuation of the optical fiber cable should be smaller than the fiber
converter's Link Budget.

JetCon 2401
Overview
JetCon 2401 is a Multi-serial to fiber media converter which has RS-232/RS-422/RS-485
triple mode circuits with auto baud rate and direction control functions. It extends the
distance of serial communication to 5KM (JetCon 2401-m Multi-mode Optical Fiber) or
40KM (JetCon 2401-s Single-mode Optical Fiber) and also provides good immunity of
EMI/EMS. For the ESD protection, JetCon 2401 also passed the 15KV ESD testing on serial
line.
To ensure nonstop transmission in hazardous environment, JetCon 2401 supports wide
operating temperature range, -20~70
o
C model (JetCon 2401) and -40~70
o
C model (JetCon
2401-w). Further more, JetCon 2401 supports wide range power input (DC/AC) and DIN
rail mount for quick and easy installation.

Grounding JetCon 2401
There is one earth grounding pole include in power-input
connector. Connect the earth grounding of JetCon 2401
which is within power-input terminal block to ensure
system safety and prevent noise to interfere communication.
Wiring the Power Inputs
1. Insert the positive and negative wires into the V+ and V-
contact on the terminal block connector.
2. Tighten the wire-clamp screws to prevent the power wires
from being loosened.
Notes: The recommended working voltage is DC24V
(DC12~ 48 V) or AC24V (AC 12~32V) with polarity
reverse protection.
Connecting to serial line
The JetCon 2401 provides triple mode circuits for RS-232/RS-422/RS-485 2/4-wires and
extend these signals to 5KM or 40KM by optical fiber cable.The converter operating
architecture can also configure as a PTP (Peer to Peer) or SFR (Serial Fiber Ring) to enlarge
