MULTINET4 MULTI-PORT SERIAL SERVER & MANAGED SWITCH – INSTRUCTION MANUAL
GETTING STARTED
CHAPTER 2: GETTING STARTED
5.
Tighten the saddle screws until the wires are secure.
6.
Re-insert the plug into the phoenix connector and secure the two captive mounting
screws.
Note
Serial cables must be shielded. It is recommended that high quality Belden 9843 cables be
used whenever possible to provide reliable serial communication.
2.3.4.2 Connecting RJ45 Twisted Pair
The RJ45 ports of the Multinet4 can be connected to the following two media types:
100Base-TX and 10Base-T. CAT Five cables should be used when making 100Base-TX
connections. When the ports are used as 10Base-T ports, CAT.3 may be used. In either
case, the maximum distance for unshielded twisted pair cabling is 100 m (328 ft.).
Note
It is recommended that high quality CAT. 5 cables (which work with 10 Mb and 100 Mb) be
used whenever possible to provide flexibility in a mixed-speed network, as dual-speed
ports are auto-sensing for 10 and 100 Mb/s.
The following procedure describes how to connect a 10Base-T or 100Base-TX twisted pair
segment to the RJ45 port. The procedure is the same for both unshielded and shielded
twisted pair cables.
Z
Using standard twisted pair media, insert either end of the cable
with an RJ45 plug into the RJ45 connector of the port.
Even though the connector is shielded, either unshielded or
shielded cables may be used.
Z
Connect the other end of the cable to the corresponding device.
Z
Use the LINK LED to ensure connectivity by noting that the LED will
be illuminated when the unit is powered and connection is
established.
2.3.4.3 Connecting ST-type Fiber Optics (twist-lock)
The following procedure applies to installations using modules with ST-type fiber
connectors.
Z
Before connecting the fiber optic cable, remove the protective dust
caps from the tips of the connectors on the module.
Save these dust caps for future use.
Z
Wipe clean the ends of the dual connectors with a soft cloth or
lintfree lens tissue dampened in alcohol.
Ensure the connectors are clean before proceeding.
Note
One strand of the duplex fiber optic cable is coded using color bands at regular intervals.
The color-coded strand must be used on the associated ports at each end of the fiber optic
segment.
Z
Connect the transmit (TX) port on the module (light colored post) to
the receive (RX) port of the remote device.
Begin with the color-coded strand of the cable for this first TX-to-
RX connection.
