Installing Coaxial Cable Connectors
BMTW-SVN01F-EN 165
9. Crimp the small end of the ferrule onto the cable. An example of a
completed coaxial cable termination is shown in Figure 79.

10. With an ohmmeter, make sure that the center conductor to BCU
chassis ground is greater than 2 MΩ (megohms). If it is less than
2MΩ, determine the reason before continuing.
11. With an ohmmeter, make sure that the ferrule to BCU chassis ground
is greater than 2 MΩ. If it is less than 2 MΩ, determine the reason
before continuing.
12. With an ohmmeter, make sure that the center conductor to ferrule
connection reads greater than 2 MΩ.
• For ARCNET LAN: If the ohmmeter reads 93–105 Ω, the other
end has a tee and is terminated.
• For Ethernet LAN: If the ohmmeter reads 50–55 Ω, the other end
has a tee and is terminated.
• If the ohmmeter reads 2 Ω, make sure the other end is not con-
nected.
• If the ohmmeter reads 0 Ω, there is a mistake in the preceding
steps. Review these steps to determine the error.
13. To aid in terminating the other end of this cable, take the tee and ter-
minator shipped with this BCU and put them on this end of the cable.
Then, put the metal BNC, tee, and terminator in insulation to isolate
it from the BNC chassis ground.
14. Repeat this procedure for all other cables in this BCU.
Note:
Different ferrules are required for the following:
• Plenum RG-62
• Non-plenum RG-62
• Plenum RG-58
• Non-plenum RG-58
