Preparing the Coax Cables
The RJ-45 and LAN pin assignments are listed in Table 8 .
Table 8. RJ-45 Pin Assignments
A diagram of the pin numbering scheme is shown in Figure 5 .

The LAN port is normally assigned to the WAN (towards the VPN). Its IP address is the next
hop for the VPN.
4.7 Preparing the Coax Cables
Use high quality coaxial cable to connect the iDirect Evolution X1 Satellite Router to the ODU
equipment. iDirect recommends that you use a solid copper center conductor, quad shield,
coaxial cable with a minimum of 60% + 40% braid and double foil shield to connect the IDU to
the ODU equipment, such as:
•
RG-6 — 0.04 inch (1 mm), solid bare copper center conductor (CommScope 5782)
• RG-11 — 0.064 inch (1.6 mm), solid bare copper center conductor (5902)
The center conductor must be straight and extend 1/8 inch (3.2 mm) beyond the end of the F-
connector, and the connector should be securely crimped to the cable.
Note: iDirect does not recommend using RG-59 with solid bare copper center
conductor unless the IFL length is less than 120 feet (37 m). If lower RF
insertion loss is required due to the distance between the IDU chassis and the
ODU equipment, then RG-11 or other 75-ohm types of coax can be used.
If you use different types of coaxial cable other than the recommended quad shield RG-6 or
RG-11, the following problems can occur:
