Introduction
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
o o
operating temperature range, -20 C~70
(JetCon 2401-w).
Further more, JetCon 2401 supports wide range power input (DC/AC) and DIN rail mount for
quick and easy installation.

Mounting the Unit
 Din-Rail mount: screw up the DIN rail mount kit
with 4 screws and mount JetCon 2401 on the DIN Rail.
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.
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
the serial communication infrastructure and link more JetCon 2401. To ensure the quality of
serial line signal, JetCon 2401 provides 2 termination resistors for the RS-422/485 TX and
RX signal by DIP switch enabled/Disable. About the DIP Switch setting, please refer to DIP
Switch setting table.The following information will show the different serial signal
connectivities for your reference.
