PCS-1500/1500P
3. Interface between camera (PCS-C150/C150P) and remote commander (PCS-R150) :
Infrared ray
The IR receiver on the front panel of the camera (PCS-C150/C150P) receives the SIRCS signal that is
transmitted from the remote commander (PCS-R150). The SIRCS signal 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 configuration
and the user setup. (Refer to Operating Instructions.)
4. Interface between compact processor (PCS-P150/P150P) and
external microphone (PCS-A300/option): Mini-jack
Power :
Power of about 2.9 V DC is supplied to an external microphone (PCS-A300) from the compact
processor (PCS-P150/P150P). (Plug-in Power)
Audio signal :
The audio signal of
_
33 dBs from external microphone is input to the compact processor
(PCS-P150/P150P).
