(default)
JP1 (OPT/RX): optical connector or BNC
OPT (default) : Biphase signal is supplied to AK4112A by optical connector.
RX
: Biphase signal is supplied to AK4112A by BNC connector.
n The indication content for LED.
[LE1] (ERF) : AK4112A unlock and parity error output.
[LE2] (FS96) : AK4112A 96kHz sampling detect.
[LE3] (AUTO) : AK4112A AC-3/MPEG detects.
[LE4] (V)
: Validity.
n The function of the toggle SW.
[SW3] : Resets the AK4528, AK4112A and AK4353. Keep “H” during normal operation.
n Serial control mode
The AK4528 can be controlled via the printer port (parallel port) of IBM-AT
compatible PC. Connect PORT2 (CR-I/F) with PC by 10-wire flat cable
packed with the AKD4528.
Take care of the direction of connector. There is a mark at pin#1.
The pin layout of PORT1 is as Figure 4.
