15. SYSTEM DESCRIPTION
15.1. Serial Interface RS232
The RS232 interface is led through a 6-pin RJ25 connector on the board.
Baud Rate:
600 – 115,200 bps
Data Bits
= 7, 8
Stop Bits
= 1, 2
Parity
= none, even, odd
Flow Control
= RTS/CTS, XON/XOFF
The input printer buffer has a capacity of
5K
bytes.
When the buffer reaches 2/3 of the total capacity (i.e.
3413
bytes), printer sends XOFF(13h)
and asserts the CTS. As soon as the buffer reaches 1/3 of the buffer capacity (i.e.
1706
bytes) printer sends an XON (11h) and de-asserts CTS signal.

15.2. USB Interface
The USB interface is connected through a USB-mini-B receptacle connector.
The elec. board complies with the USB specification V1.1 for full speed devices (12 Mbit/s).
The printer is compatible with USB V2.0 bus systems with full speed data transfer.
The USB Device Class is consistent with the "Printer Class".
After the PC is plugged in, it reports "USB printer support" and installs a "USB001" USB Port or
subsequent port enumeration.
