printer handles only the "Busy" signal.
This parameter determines whether the "Select-In" and/or "Paper Empty" signals will be selected in
addition to the "Busy" signal (which is always used).
Operating Mode : data is usually sent to the parallel port through a method based on 'interrupts'.
This makes efficient use of the AX3000 CPU.
In event of problems (no printing or a very slow printing), it is possible to change this parallel port
management and to send data by a 'polling' method. To enable this method, set the "Operating
Mode" parameter to "Standard".
Transmit FIFO, AUX1 and AUX2 ports : the AUX1 and AUX2 ports provide an embedded transmit
buffer (FIFO). This allows the data transmission to be optimized. By default this mechanism is
enabled.
If necessary this parameter allows the AUX1 (or AUX2) FIFO buffer to be disabled.
d) Mass Storage Device Menu
LUN Number : some USB drives may be formatted in multi-LUN mode (multiple partitions). But the
Axel Thin Client handles only a single LUN. This option allows the LUN number to handle to be
selected. (If the LUN Number is too high, the LUN #0 will be used).
Enhanced FAT Readahead : this option allows performances to be increased. It could be disabled.
External USB mas
s storage devices (memory sticks, hard drives, CD/DVD readers…) are
redirected to the Windows/Citrix server and are seen as local drives
The USB drive parameters are:
- Access Permission : 'Read Only' and 'Read/Write'
- Driver Letter : mnemonic given to the Windows server.
Simulate PnP (ICA) : hot plug is not supported by old Citrix versions. This option allows a
redirected USB mass storage to be announced even is no physical device is plugged.
