3-1-1. Interface between Devices

The Compact Conference Package PCS-1500/1500P consists of the compact processor (PCS-P150/
P150P), camera (PCS-C150/C150P), external microphone (PCS-A300/option) and remote commander
(PCS-R150). This section describes the interface between these devices.
1. Interface between compact processor (PCS-P150/P150P) and
Power :
The +12 V DC power that is supplied to the compact processor (PCS-P150/P150P) from the AC
adapter, is at the same time sent to the camera (PCS-C150/C150P) through a switch and fuse.
Video signal :
The video signal that is created by the camera (PCS-C150/C150P) is input to the compact
processor (PCS-P150/P150P) in the form of a YC video signal.
VISCA signal :
The setup and operation of the camera (PCS-C150/C150P) are controlled from the compact
processor (PCS-P150/P150P) using the serial VISCA signal. The camera (PCS-C150/C150P)
status is also read using the VISCA signal by the compact processor (PCS-P150/P150P).
n
The Automatic Target Tracking Function is contained by the camera (PCS-C150/C150P) itself;
the compact processor (PCS-P150/P150P) sends the setup command only.
SIRCS signal :
The IR receiver of the camera (PCS-C150/C150P) receives the SIRCS signal that is then sent to
the compact processor (PCS-P150/P150P) after the carrier component is removed.
n
Whether the IR receiver of the camera (PCS-C150/C150P) or that of the compact processor
(PCS-P150/P150P) is used for receiving the SIRCS signal, is determined by the system configu-
ration and the user setup. (Refer to Operating Instructions.)
LOCK signal :
The LOCK signal is used for the compact processor (PCS-P150/P150P) to recognize whether the
camera (PCS-C150/C150P) and the compact processor (PCS-P150/P150P) are connected
directly or by using an extension cable.
GND level : Direct connection
Open : Connection using an extension cable
2. Interface between compact processor (PCS-P150/P150P) and
The IR receiver on the front panel of the compact processor (PCS-P150/P150P) receives the SIRCS
signal that is transmitted from the remote commander (PCS-R150).
n
Whether the IR receiver of the camera (PCS-C150/C150P) or that of the compact processor
(PCS-P150/P150P) is used for receiving the SIRCS signal, is determined by the system configuration
and the user setup. (Refer to Operating Instructions.)
