SETTING RECEIVER CONFIGURATION
The Pyramid 2 Keyboard can be used to specify the configuration of any receivers that are connected to cameras within the
Pyramid system.
To set the configuration of a receiver, follow the steps below:
1. Select the PTZ camera to which the receiver is attached - see
Selecting a Camera on page 14.
2. Press the Utility Menu screen key.
3. Press the Receiver Utilities soft-key.
4. Press the Rx Config soft-key. The Receiver Configuration screen is displayed (Figure 75).

5. Some PTZ units are capable of continuous rotation (360 O ). A small gap can exist in the feedback potentiometer, and
this gap is known as the dead band. If a continuous rotation PTZ head is being used, press the Non-Cont soft-key, so
that the receiver is configured for a continuous rotation PTZ unit. The text on the soft-key changes to Cont .
The default setting is to leave the soft-key displaying the text Non-Cont (i.e., non-continuous PT head operation).
6. Receivers are supplied with feedback potentiometers enabled. If there are no feedback inputs to the receiver, the
manual operation of the PTZ unit will be affected (e.g., the pan and tilt controls will only operate in one direction), since
the feedback inputs are used as a constant check for end stops. If this is the case, disable the feedback potentiometers
to correct the problem and enable manual PT operation. To do this, press the F/B soft-key, so that the text changes to
No F/B .
The default setting is to leave the soft-key displaying the text F/B (i.e., feedback potentiometers enabled).
7. In some cases, zoom lenses have three wire control of zoom and focus functions (i.e., Ground, Zoom +/-, Focus +/-)
rather than the usual four wire control. If this is the case, the receiver needs to be configured for the use of a 3-wire lens,
so that it carries out the zoom operation first followed by the focus operation on preset recall. To do this, press the 3
Wire Lens soft-key.
The default setting is to leave the 3 Wire Lens soft-key off (i.e., in four wire control).
8. Press the Enter soft-key to confirm the selection and to send the information to the receiver.
9. Press the Utility Menu screen key to leave the Receiver Configuration screen.
