(Optional)
Important: There should be direct DC path from the PAC through Bias-T to the antenna in order for
the remote control signal to flow up to the antenna. If additional lightning protection is required, use a
lighting arrestor with DC bypass feature.
4.4 Connecting Optional PAC Communication Cables
When configuring PAC using the PAC PC Application software or connecting PAC to the base station,
use RS-232 cable (included in the PAC Kit) and/or RS-485/422 cable (not included in the PAC Kit) to
connect the PAC to a PC or to a base station system as shown in Figure 4-4.
