The EasyCoder 501 XP is as standard always fi tted with one
RS-232 communication port. In Intermec Fingerprint, this port is
designated "uart1:" (Universal Asynchronous Receiver and Trans-
mitter.) The circuitry is fi tted on the CPU board (see Chapter 15)
and has a fi xed set of signals in a DB-25pin male connector which
protrudes through a slot in the printer's rear plate.
By default, the printer is set up as follows:
Baud rate .................... :
Parity .......................... :
Char. length ................ :
Stop bits ..................... :
RTS/CTS .................... :
ENQ/ACK.................. :
XON/XOFF................ :
New line ..................... :
The external +5V is limited to 200 mA and is automatically turned
off at overload. It is intended to drive for example an external
alphanumeric keyboard or a bar code reader.
