Electrical Substation-Rated
10/100/1000 Mbps Ethernet Media Converter
This manual serves the following
ComNet Model Numbers:
RLMCSFP24DC
RLMCSFP48DC
RLMCSFPHV
The ComNet RLMCSFP is designed for deployment in environments where high
levels of electromagnetic noise and interference (EMI) and severe voltage transients
and surges are routinely encountered.
The DIP-switch-selectable 100BASE-FX or 1000BASE-FX port supports conventional
CAT-5e/CAT-6 copper or optical transmission media by selection of the appropriate
ComNet SFP module.
User-selectable link fault pass-through provides remote indication of a network fault,
and a summary fault alarm provides a local or remote indication via Form C dry
contact closure in the event of loss of optical link or operating power.
The 10/100/1000BASE-TX port supports both auto-negotiation and automatic MDI/
MDI-X crossover for full and half-duplex operation; manual MDI/MDI-X switching is
not required.
LED indicators confirm operational status.
See Figures 1 – 6 for complete operation details.
The RLMCSFP is DIN-rail or panel-mountable. See Figure A on the last page for
mounting instructions.
Locate the 100/1000 data rate DIP switch on the bottom panel of the unit.
Set the data rate according to bandwidth required.
NOTE: If two units are connected via the SFP Port, the data rate must be set the same on both units, and must match the
data rate of the installed SFPs. Data rate settings are read on start-up, so restart the unit after making any changes.
2 - SET FAULT DIP SWITCHES (UTP MODELS ONLY, FOR COAX MODELS SKIP TO STEP 3)
Locate the LFE, FFE, and PSE DIP switches on the bottom panel of the unit.
LFE1: If the Copper Port is Down or Not Connected, the Optical Port will turn on and off at a ~1 sec rate to indicate copper port
fault and the alarm relay will be triggered.
FFE: If the optical link is lost or there is a power failure then the alarm relay output will be triggered.
NOTE: You may select multiple fault event triggers.
NOTE: Power Supply Fault DIP Switch is only available on Redundant Power Models. When a redundant power supply is
available, a failure of power on one power supply will trigger the alarm relay output.
NOTE: Restart not required when making changes to this DIP switch setting.
100 Mbps Speed Set Speed must match speed of installed
SFP. Reset power if switch or SFP is changed.
1000 Mbps Speed Set. Speed must match speed of
installed SFP. Reset power if switch or SFP is changed.
3 - CONNECT GROUND WIRING
Connect Ground Wiring to ground screw and tighten nut to secure.
4 - CONNECT FAULT RELAY WIRING
Connect Fauly Relay device to 3-pin terminal block. The COM to N/O will be shorted in the fault condition.
5 - CONNECT DATA WIRING
Connect RJ-45 Ports to field wiring using Cat5/5e/6 cable.
6 - CONNECT NETWORK WIRING
Using fiber optic cabling appropriate to the installed SFP, connect the unit to a network device.

Figure 6 - Fault Relay Operation
The fault relay is normally closed and will open on any of the following alarm conditions:
- Link Fault is enabled on the remote RLMCSFP unit and the corresponding copper port has been
disconnected.
- Link Fault is enabled on the local RLMCSFP unit and the corresponding copper port has been
disconnected.
- Fiber Fault is enabled on the local RLMCSFP unit and the fiber link is down or the power has been lost to
either the local or remote RLMCSFP unit.

ProblemSteps to Take
Power LED not lightingCheck that power is properly applied to the unit using the correct connector pair.
No CommunicationCheck Ethernet Link LEDs, Fiber Optic Link LEDs. Confirm Connections, DIP switches are set properly. Verify that the Data Rate switches are set
to the same data rate on back-to-back units and match the installed SFP. Restart the unit if the Data Rate Switch or installed SFP has changed.

MECHANICAL INSTALLATION INSTRUCTIONS
Installation Considerations
This product is supplied as Standalone/Surface Mount module. Units should be installed in dry locations protected from extremes of temperature and humidity.
WARNING: Unit is to be used with a Listed Class 2 power supply.
IMPORTANT SAFEGUARDS:
A) Elevated Operating Ambient - If installed in a closed or multi-unit rack assembly, the operating ambient temperature of the rack environment may be greater than
room ambient. Therefore, consideration should be given to installing the equipment in an environment compatible with the maximum ambient temperature (Tma)
specified by the manufacturer.
B) Reduced Air Flow - Installation of the equipment in a rack should be such that the amount of air flow required for safe operation of the equipment is not compromised.
