Description:

This driver controls the Pioneer VSX-84TSXi A/V receiver.

Quirks and Limitations:

When the receiver is in standby (“off”), any writes to the RS232 port will cause it to power-on. This has two results....first, changing any CQC field for the receiver will result in the receiver powering on, and then executing the requested command. This is working as designed...just be aware. It also means that the receiver will be powered on when the driver loads, since it must talk to the device in order to get its initial status.

The second result is that this driver will do no polling of the device because testing has shown this to be very quirky. All this means is that if the receiver becomes physically disconnected from the controlling PC, this won't be evident immediately. In fact, it won't become known until you try to issue a command via CQC field, and see no change result. Polling of this device is not necessary for 2-way communication.

Connection Details

This driver connects via RS-232, at 9600 baud, 8-data bits, no parity, and 1 stop bit. You must use a null modem cable.
