S_BAUD 1200, 2400, 4800, 9600, 19200, 38400, 57600,
115200 bps
S_DEVID 0 to 32767
S_T1 0.1 to 10 s
S_T2 0.2 to 25 s
S_T3 1 to 120 s
S_T4 1 to 120 s
S_RTY 0 to 31
S_MS M: Master
S: Slave
1: The header of the block currently being
received is compared with the correct block
received immediately before, and double
blocks are detected.
0: Double block detection is not performed.
S_SRC 0 to 32767
S_BNO 0, 1
C_BAUD 9600, 19200, 38400 bps
Use a consistent baud rate setting within the
same system configuration.
C_HEAD 0 to 31
0: The number of heads is automatically
detected at the start. Any increase or
decrease in the number of heads is auto-
matically detected.
1 to 31: The number of heads is specified. The
number of heads detected is compared
with this specified number of heads. If the
number of heads changes, for example
because a head fails, an error (with
alarm) is detected.
If a head is not connected or an error is
detected with a connected head, so that
the number of heads does not match the
specified number, an error (with alarm) is
detected.
