10.3.2 Communication Protocol
The DigiFlow 515 has a build in real time clock. This enables the time and date to be set and printed on tick-
ets.
Make sure you that the clock keeps its setting at loss of the energy only for about 5 days. After then the clock
may need to be set.
The baud rate can be adjusted at the configuration. The user must worry for this, that the settings agree of
computers and
DigiFlow 515 so that the communications can take place.
10.3.3 Printers Protocol
A ticket can alternatively be created after actuation of the RESET–key, or after defined intervals (see key
lock). At interval wise expression a reset of the sum counters can simultaneously be done.
If the RESET operation is triggered, first the ticket is created and after this the total values are reset internally.
The communications with printers take place without handshake lines. At this is presupposed that the printer
buffer correspondingly is large enough and cannot (also at print intervals) overflow. A ticket looks as follows:
