Choosing the Timeout Period

When any twinax, parallel or serial input port has stopped using an output
port for a user-configurable timeout period, the OPTIMA considers the
output port available and gives it to the next input port in the queue.
The timeout period should be as short as possible to prevent too much time
being wasted between print jobs from different sources, but it should not
be so short that a job from one source could interrupt a job from another
source.
For most twinax hosts, a timeout of five seconds should be fine. For
parallel and serial alternate hosts connected to IBM PCs or compatibles,
the timeout value may need to be increased when running complex graphic
applications that take time during printing to compute the image. Some
applications may require timeout values as large as one minute.
To change the length of the timeout period, at the appropriate port on the
OPTEDIT main screen, use the arrow keys to move the cursor to the word
Timeout= (the default is 5 seconds), and press ENTER. The user will be
presented with a choice of times ranging from one second to one minute.
Use the arrow keys to move the cursor to the appropriate time, and press
ENTER. After the timeout period has been selected, the OPTEDIT main
screen will return.
Configuring the Twinax Ports
The OPTIMA supports up to three twinax ports simultaneously. Each of
these three addresses may be configured separately for a different type of
IBM printer emulation, character translation, mode of operation, etc. If the
user intends to use more than one twinax address, each one must be
configured independently.
For a twinax port to be used, the user must activate it, choose the output
port(s), specify the timeout period and select the mode, as described
earlier. Then the user must set its address and choose the appropriate
emulation.
If using a Xerox printer, the user should also refer to the section that
follows, entitled Interfacing Xerox Printers. Note: Two of the options
described in the Xerox section (PFS Suppression and Form Feed
Suppression) will also affect non-Xerox printers.
