The following protocols can be used:
• IrDA:
IR LPT (printer service)
IR COMM 9 wire (optional)
Also see:
www.irda.org
• GeBE-IR:
simple, error-proof,
bidirectional,
dot-to-dot IR protocol.
GeBE-Doc.No. MAN-D-394
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-4454.
The internal IR tranceiver is installed directly below the
red foil window (10). It is important to consider that inf-
rared transmission only works "at sight". The radiation
angle is about ±15 degrees. The transfer distance to
"IrDA standard power" devices is 1.0 meter.
Use of the Sleep Mode
In the setting "IrDA "or "GeBE IR", the IR receiver will
even stay active in the sleep mode, so the device will
not have to be swiched on explicitly for printing. The po-
wer consumption of the printer is only about 25µA in
this mode. However, the printer should still be turned off
during long periods of inactivity.
GeBE -IR Protocol
The GeBE-IR protocol is a simple, error protected infra-
red protocol. Data transmission is processed in CRC
protected blocks.
With each transmission confirmation, the printer status
is sent back to the host.
The implementation is very easy to realize. The protocol
is disclosed.
IrDA Protocol
The printer works with the protocol service IrLPT. In this
service, the printer will not send back any messages.
A bidirectional service "IrCOMM 9 wire" is available on
request.
In the menu setting, the selected baud rate represents
the maximum baud rate. If 57,600 baud is selected, for
6.3 Infrared Interfaces
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 re-
duced, if transmission errors occur.
When an infrared transmission is interrupted, the printer
will look for the transmitting master device for about 20
seconds in order to complete the transmission. After
that, the stack is reset, and new inquiries are answered.
