Introduction

The RocketLinx MC5001 is a serial to fiber media converter with an RS-232/422/485 port with
auto sensing baud rate and direction control functions. It extends the distance of serial
communication to 5KM (MC5001, Multi-Mode) or 40KM (MC5001, Single-Mode) and also
provides good immunity for EMI/EMC. The RocketLinx MC5001 supports 15KV ESD
protection on the serial line. It also features a wide power input range
(12-48VDC/12-32VAC) and DIN rail mounting for quick and easy installation.

Mounting the RocketLinx MC5001

DIN Rail mount: screw on the DIN rail mounting clips
with the four screws and mount MC5001 on the DIN Rail.

Grounding the RocketLinx MC5001

There is one earth grounding pole included on the
power input connector. Connect the earth ground of the
MC5001 to ensure system safety and to prevent noise.

Wiring the Power Inputs

1. Insert the positive and negative wires into the
V+ and V- contacts on the terminal block connector.

2. Tighten the wire-clamp screws to prevent the
power wires from being loosened.

Note: The recommended working voltage is 24VDC (12-48VDC) or 24VAC (12-32VAC)
with polarity reverse protection.

Connecting to serial line

The MC5001 provides triple mode circuits for RS-232/422/485 2/4-wires and extends these
signals to 5KM or 40KM by optical fiber cable. The converter operating architecture can also
be configured as a PTP (Peer to Peer) or SFR (Serial Fiber Ring) to enlarge the serial
communication infrastructure and link additional MC5001s.
To ensure the quality of the serial line signal, the MC5001 provides two termination resistors
for the RS-422/485 TX and RX signal by using the DIP switch enable/disable option. Refer to
the DIP switch setting table for more information.

Connecting the Optical Fiber

The Fiber Optical link architecture supports PTP
and SFR mode for different purposes.

PTP Mode (Peer to Peer)

The PTP (Peer to Peer) mode provides connection
between 2 nodes. When working in this mode, the
MC5001 can transmit and receive data at the same
time, which means the MC5001 is working at
full-duplex mode.
