FC1 Protocol

The following protocols naturally correspond to the external memory unit, YASNAC FC1 or FC2.
 RS050: NUMBER OF DATA BITS
This parameter specifies the number of data bits.
 RS051: NUMBER OF STOP BITS
This parameter specifies the number of stop bits.
 RS052: PARITY
This parameter specifies the parity bits.
 RS053: TRANSMISSION SPEED
This parameter specifies the transmission speed in units of bauds.
 RS054: RESPONSE WAITING TIMER (TIMER A)
Units: 0.1 seconds
This timer monitors the sequence. It specifies the response waiting time for invalid or missing
responses.
RS055: TEXT TERMINATION MONITORING TIMER (TIMER B)

This timer monitors text reception. Specify the monitoring time to wait for text termination character.
 RS056: NUMBER OF ENQ RE-TRANSMISSION RETRIES
This parameter specifies the number of re-transmission attempts of the control characters for invalid or
missing responses.
RS057: NUMBER OF DATA RE-TRANSMISSION RETRIES

This parameter specifies the number of re-transmission attempts of text for block check error (NAK
reception).
 RS058: FC2 FORMAT SPECIFICATION
Specify the format type of the floppy disk used with external memory (YASNAC FC2).
720 kilobytes are unconditionally specified for YASNAC FC2 (2DD floppy disk exclusive
NOTE
use).
 RS059: EXTERNAL MEMORY FILE OVERWRITE
SPECIFICATION
Specify whether to accept the file overwrite of the external memory (YASNAC FC2 or FC1).
