Q: Does Toshiba HD-A1 support discrete on/off?
A: Partially, there is a IR code that functions as discrete on, but no discrete off. You can either use the discrete on IR available in the JP1 upgrade, or you can use "Play" as a substitute for discrete on. For discrete off, you will need to have some sort of device state tracking as the trusty old "Play/PowerToggle" substitute for discrete off will not work because the HD-A1 does not respond to IR until it is finished booting and it takes so long to boot.
EDIT: after looking over the RS232 commands it appears there is a discrete off function, but it was confirmed not to work via both IR and RS232 by dheiskel. This was with 1.4 firmware.http://www.avsforum.com/avs-vb/showt...&&#post7980603Power Toggle
- RS232/IR hex 12h , JP1 EFC 119 , JP1 OBC 018Discrete On
- RS232/IR hex 92h , JP1 EFC 127 , JP1 OBC 146Discrete Off (not working)
- RS232/IR hex 93h , JP1 EFC 131 , JP1 OBC 147Please complain to Toshiba about discrete off not functioning properly for IR and RS232. This is the only way to get it fixedQ: Where can I find a list of IR/RS232 functions
A: A list of the RS232 commands supported by the Toshiba and related siblings was posted on remote central. It was noted by dheiskel and others that the function codes map exactly to the IR codes.http://www.remotecentral.com/cgi-bin...hread.cgi?1160http://www.avsforum.com/avs-vb/showt...&&#post7807264
UPDATE: Mark Rubin gives information on how to get RS232 workinghttp://www.avsforum.com/avs-vb/showt...&&#post8193553
a few folks have gotten the serial commands to work:
you must use a null modem adapter since pins 2 & 3 are reversed: there is no feedback from the XA-1 (one-way only, not bidirectional)Q: Where is JP1 upgrade for Toshiba HD-A1?
