All standard versions of the printer have the hardware
for an IR transmitter/receiver installed, so the protocols
GeBE-IR and IrDA are available for all standard printers
of the series GPT-437x.
The inter nal IR tranceiver is installed dir ectly below the
r ed foil window (10). The GPT -4379 has an LED next to
the transceiver that signals any IR communication. It is
important to consider that infrared transmissions only
work "at sight". The radiation angle is about +/-15 de-
grees. The transfer distance, which also strongly de-
pends on the efficiency of the opposite side, is about
1.0 meter. It can be expanded to < 3 meters by in-
stalling a booster-IR LED.
Use of the Sleep Mode
In the setting "IrDA "or "GeBE IR", the IR r eceiver will
even be active in the sleep mode, so the device will not
have to be switched on explicitly for printing. The po-
wer consumption of the printer is only about 25µA in
this mode. However , the printer should still be tur ned
of f during long periods of inactivity .
GeBE -IR Pr otocol
The GeBE-Ir pr otocol is a simple, err or pr otected infra-
r ed pr otocol. The data transmission is pr ocessed in
CRC pr otected blocks.
With each transmission confirmation, the printer status
is sent back to the host.
The implementation is easy to r ealize. The pr otocol is
disclosed.
5.2 Infrar ed Interfaces
IrDA Pr otocol
In the menu setting, the selected baud rate r epr esents
the maximum baud rate. If 57,600 baud is selected, for
example, the printer will start to communicate with
9,600 baud and then switch up to 57,600 or 38,400
baud, depending on the transmitter .
The maximum baud rate of 115,200 should only be r e-
duced, if transmission pr oblems occur .
When an infrar ed transmission is interrupted, the printer
will look for the transmitting master device for about 20
seconds in or der to complete the transmission. After
that, the stack is r eset, and new inquiries ar e answer ed.
