Quote:
The player's serial port is DCE so that it can be connected with a null modem cable to a PC (which are usually DTE). The sled connector on the other hand is a modified DTE with only TX and RX brought out. Pin 4 (usually DCE Ready) has the amp remote line on it. This is 12V switched with the VFD screen - ie, if the VFD is on this is 12V. You cannot control this separately.


Incorrect genixia. The built in serial port is DTE not DCE which is why you need the null modem. The sled serial port is a mixture of DTE and DCE. See here for reference.
