The left contact on the connector is common; the right contact is the positive (+) voltage
(→ Fig. 3).
Note: USB Signal GND and power GND are connected to each other.
4.5.2 Data Interfacing USB
T eXtendo® XF printer employ USB2.0 connection a standard digital camera USB interface
cable (5 pin Mini-B connector on the printer end) to communicate with the host. Be sure

Please note that the shell of the USB connector only makes a capacitive connection to the
signal ground.
Please observe the notes regarding signal grounding in → Chapter 2.2.
4.5.3 Data Interfacing RS232
The printer is shipped with the following serial settings as default: 115,200 baud, 8 data
bits, one stop bit, no parity, hardware flow control, and host transmission not blocked (this
last feature is intended for use with lower sophistication hosts that cannot read the
eXtendo® XF printer's status data. It uses the hardware handshake lines to prevent the host
from sending more data if the printer registers "paper out").
The eXtendo® XF printer uses a JST ZHR-6 connector shell with JST SZH-002T-P0.5 contacts
to make the RS-232 connection. Hengstler can provide a serial cable for direct connection
to PCs with a DB-9 connector on one end (→ section 12 Spare Parts and Accessories).
Connections are as follows, should you decide to make your own data cable or connectors.
