3.3 RF Inputs
The RF inputs are:
• Course Line - CL.
• Near Field Antenna - NF.
• Displacement Sensitivity - DS.
• Clearance - CLR (two frequency applications only).
These are connected as shown in Figure 3-4 (front view)
.
Figure 3-4 RF input connections.
3.4 RF Outputs
The RF outputs are sited at the cabinet top as illustrated in Figure 3-5. The connections are:
All applications:
