SOFTWARE MANUAL C32
1.1.2
SERIAL INTERFACES RS232 / TTL 3.3V
The serial interface RS232 can be operated with V.24 level up to 460 kbps,
with TTL level even up to 3.6 Mbps.
The input buffer is adjustable from minimum 1 kbyte to maximum 4 kbyte by parameter. With 1 kbyte being default
(
parameter 13,1
). The buffer overhead is adjustable from 32 byte to 255 byte by parameter with 64 byte being default
(
parameter 13,2 and 13,3
).
In case the memory reaches the set buffer overhead size, the controller switches the CTS-line onto stop and sends the
control code <XOFF> via serial data line to the host. This stops the data stream from the host to the controller. This
means, that the printer sends 64 byte until the buffer is filled-up and a <XOFF> (13h) sets the busy signal.
When the buffer decreases down to 128 characters the controller releases the CTS-line (level change) and a control code
<XON> (11h) will be send to the host for further data transfer.
1.1.3
HARDWARE HANDSHAKE
The sending data source (host or data controller) recognizes whether the receiving side is able to accept data or not. This
is usually indicated by the status of the potential level being present on the hardware wires.
At data receipt, the printer controller monitors the handshake line CTS (clear to send) together with the whole input buffer
control. Through the data lines, the signal is simultaneously controlled together with the performed software handshake
( <XON>/<XOFF> protocol). When sending data e.g. status messages to the host,
parameter 10,6
can select whether the
printer considers a host hardware handshake or not. Default is: not consider.
1.1.4
SOFTWARE HANDSHAKE
The control of data transfer from host to controller is not only made by hardware handshake but also per <XON>/<XOFF>
protocol. The decision between both methods is made according to the options and the settings of the host software.
1.1.5
TROUBLESHOOTING
Not implemented yet
In case of a defective character, the printer prints a „?“ (at parity or framing error) and a „!“ (at overrun error). Subsequently a
„X“ will be sent via serial interface. As default: printing „?“ at parity or framing error is not activated.
