2.6 Serial Input/Output
If BUSY control is selected:
When 236 bytes of data have been stored in the input buffer, the
SBUSY signal becomes high to request that the computer temporarily
stop sending data. When the amount of data stored in the input buffer
becomes 235 bytes or less, the SBUSY signal changes to low to
request that the host device continue data transfer. Up to 16 bytes of
input data are guaranteed after the SBUSY signal has become high.
When an error occurs, the SBUSY signal becomes high. Data input is
prohibited until the error is cancelled.
If Xon/Xoff control is selected:
When 188 bytes of data has been stored in the input buffer, Xoff (13
16
)
is output through the TxD terminal to request that the host device
temporarily stops sending data. When the amount of data stored in the
input buffer becomes 124 bytes or less, Xon (11
16
) is output to request
that the computer continues data transfer. Up to 64 bytes of the input
data are guaranteed after
Xoff has been output. When an error occurs, the Xoff signal is output to
prohibit the data input.
When the error is cancelled, Xon is output.
2.6.1 Serial data transfer
The PRN604-Stransfers various data other than the Xon and Xoff
codes which are output when controlling Xon and Xoff.
Regardless of whether the input mode is serial or parallel, the following
data is transferred through the TxD terminal.
(a) Error codes when a hardware error occurs at initialisation
(b) The data when executing the Vhead voltage response (DC2+‘v’)
(c) The data when the error status response is set (DC2+’e’) and an
error occurs
(d) The data when executing the execution response request (DC2+‘q’)
(e) The data when executing the remaining RAM capacity response
(DC2+‘r’)
(f) The data when executing the environmental temperature response
(DC2+‘t’)
At the selection of serial input, data (b) through (f) is transferred
according to the transfer conditions, which are set using the function
