Chapter 4 HOST INTERFACE
Port Type
Select the types of parallel, serial and/or C/T interfaces which are connected
to the printer. For example, if your printer is attached to one host with a
Centronics connection and a second host with an RS-422 serial connection,
you would select Centronics under the Parallel Hotport menu, RS-422 under
the Serial Hotport menu, and Disable under the C/T Hotport menu.
Trickle Time
When the printer is printing data from a host and a second job is received by
the printer from a different host, Trickle Time prevents the second host from
timing out while it is waiting for its data to be printed. In order to support this
feature, the port has to be able to accept data from the host and store it for
future use.
For example, if the printer is printing a job from the serial port, and then
receives a second print job from the parallel port, the data from the parallel
port will “trickle” bit by bit into the printer buffer to prevent a timeout error from
being sent back to the host connected to the parallel port.
The selected value is the time that the printer waits before getting the next
byte of data from the host. The Trickle Time value should be less than the
host time out value, but not too much shorter or else the printer fills up its
buffer too fast. This function is not applicable for C/T hotport.
Timeout
This is the value used by the printer to time out from the current port and
check the other selected port types for data to print. When the printer has not
received data from the host after a certain period of time, it needs to timeout in
order to service the other ports.
Report Status
• Disable (default). When a fault occurs on the printer, only the active port
reports the fault to the host.
• Enable . The port will report any fault even when it is not the current active
port.
Switch Out On
• Data Timeout (default). Allows Autoswitching when no data has been
received for the selected Time Out period.
• Session Close . Allows Autoswitching only when the Network Socket is
closed. If the Ethernet option is not installed the Network Socket is always
reported as closed and this menu option is ignored.
