POD30 is a four by one HD-SDI video switcher with remote control capabilities. POD30 may be used in conjunction with an analog audio switcher (POD2), or a digital audio switcher (POD10) for audio following video applications. When the slave mode is enabled any channel selection on the video switcher will result in the same selection on the audio switcher and vice versa. POD30 may also be controlled remotely using its RS485 serial interface. The serial communications are eight bit, no parity, at a 9600 baud rate.
