Hardware Description SFP Speed DIP-Switch
11 AT-IMC1000TP/SFP Industrial Gigabit PoE+ Media Converter
2.5 SFP Speed DIP-Switch
The DIP-Switch is used to configure the speed of SFP Port (P2). The default value of DIP-switch is 100M.
2.6 Ports
RJ-45 ports (Auto MDI/MDIX): The RJ-45 ports are auto-sensing for 10Base-T, 100Base-TX or 1000Base-T
devices connections. Auto MDI/MDIX means that you can connect to another switch or workstation without chang-
ing straight through or crossover cabling. See figures as below for straight through and crossover cable schematic.
2.6.1 RJ-45 Pin Assignments
Note: “+” and “-” signs represent the polarity of the wires that make up each wire pair.
All ports on this industrial media converter support automatic MDI/MDI-X operation, you can use straight-through
cables (See Figure below) for all network connections to PCs or servers, or to other switches or hubs. In 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 shows the 10BASE-T/ 100BASE-TX /1000Base-T MDI and MDI-X port
pin outs.
