IATA (JIS 1 type first track): 79 characters maximum (7 bits a
character)
2 FIFOs are prepared independently to 2 channels of interface.
These FIFOs can be read simultaneously when connected to a
MCR supporting JBA/ABA or IATA/ABA.
3) When a card has been scanned, interrupts for the MCR interface
are activated.
4) The main CPU reads card data from the FIFO buffer in the inter-
rupt handling. The main CPU can read the data using IN com-
mand of 0WAIT.
Even after the LCR which is the last character of a card was read,
10 to 20 characters of "0" remains in the FIFO buffers. So it is
necessary to reset the FIFO before read enabling the next card
after reading the LCR of the last data.
5) This MCR interface does not read the next card until interrupts are
reset by the main CPU.
24. Serial Port
24-1. Outline
D-SUB 9-pin connector COM1 and COM2 are equipped.
2 channels of RJ45 Connector COM port are equipped.
COM3 and COM4 or original I/O address (COM5 and COM6) can be
selected as the 2 channels of RJ45 COM port.
In order to 5V power, CI signal and +5V power supply of
COM1 and COM2 can be switched.
