Insert the fiber optic cable into the SC or LC type connector until the self-locking 
tab clicks into position. Connect the opposite end in to a 1000 Base SX switch. 
Two types of cables are used when connecting the GigMac fiber controller to the 
network. A workstation or "straight through" cable is typically used to connect 
Ethernet adapters to switches. A fiber “crossover” cable may also be used to 
connect controllers back-to-back. This configuration is useful for loopback and/or 
diagnostic purposes or when a switch is not available.

This section explains how to connect the GigMac controller to the external 
network using the standard Category 5, 5e or 6 cables. The maximum cable 
length is typically 100 meters or 328 feet. 
 
Insert the Category 5 or 5e cable into the RJ-45 connector until the self-locking 
tab clicks into position. Connect the opposite end in to a 10/100 or 10/100/1000 
Base T switch. Two types of cables are used when connecting the GigMac 
controller to the network. A workstation or "straight through" cable is typically 
used to connect Ethernet adapters to switches. A “crossover” cable may also be 
used to connect controllers back-to-back. This configuration is useful for 
diagnostic purposes or when a hub or switch is not available. However, it is not 
recommended for extended use, as it violates the IEEE specification for 10 Mbit, 
100 Mbit and 1000 Mbit Ethernet networks. 
 
Note(1): GigMAC Models 5161, 5162, 5164, 6161 and 6162 support “auto-
MDIX” mode where a crossover cable is not required when directly attaching two 
controllers. 
 
Note(2): Cables used for Gigabit networks must use all 8 wires. In 10 and 100 
modes, wires are dedicated for transmit or receive while in Gigabit mode, data is 
transmitted and received over all 4-pairs.
