Antaira Technologies - Industrial Media Converter
IMC-100A Series User Manual V1.0

The RJ45 port on this industrial Ethernet media converter supports automatic MDI operations. Users
can use straight-through cables (
Figure 2.4 & Figure 2.5
) for all network connections to PCs, servers,
and other switches or hubs. With a straight-through cable, pins 1, 2, 3, and 6, at one end of the cable,
are connected straight through to pins 1, 2, 3 and 6 at the other end of the cable. The table below
(
Table 2.3
) shows the 10BASE-T/100BASE-TX/1000BASE-T MDI port pin outs.
The following figures show the cabling schematics for straight-through and crossover cables.
2.6 Cabling
Twisted-pair segments can be connected with an unshielded twisted pair (UTP) or shielded
twisted pair (STP) cable. The cable must comply with the IEEE 802.3u 100Base TX standard
(e.g. Category 5, 5e, or 6). The cable between the equipment and the link partner (media
converter, switch, hub, workstation, etc.) must be less than 100 meters (328 ft.) long.
Note:
The
“+” and “-” signs represent the polarity of the wires that make up each wire pair.
