5) TRNSPRNT. Transparent mode used for alternate host input. When
in transparent mode, the data output by the OPTIMA is identical to
the data received, with the exception that the data is routed through
the active translate table. This mode is not used by twinax addresses
except for diagnostic purposes.
At the appropriate twinax address or at Parallel In on the OPTEDIT main
screen, use the arrow keys to move the cursor to the word Mode= (the
default is IBM Emul for Twinax 1 and Twinax 3; 275 Emul for
Twinax 2; and TRNSPRNT for Parallel In) and press ENTER. The user
will be presented with a choice between IBM Emul, SCS Dump, 275
Emul, BLT Mode or TRNSPRNT.
Use the arrow keys to move the cursor to the appropriate choice, and press
ENTER.
After the mode has been selected, the OPTEDIT main screen will return.
Choosing the Data Routing
Each input channel is user-configurable to allow output to any
combination of output ports. When data is received from an input port
(twinax or alternate host), the OPTIMA looks at the output ports, in order
of priority, searching for an output port that is acceptable to the input
ports configuration. The first acceptable output port that is not in use by
another input port is acquired and used. If all configuration-allowable ports
are in use, the input port must wait in a queue for its turn.
The output ports have a predefined priority:
1) PO  Parallel out (if active)
2) S1  Serial 1 (if active and configured for output)
3) S0  Serial 0 (if active and configured for output  typically used
for input)
To choose the output ports to which each input port will send data, at the
specific input port on the OPTEDIT main screen, use the arrow keys to
move the cursor to the words Out To= (the default is PO,S1,S0 for the
twinax and parallel in ports; the serial port defaults exclude the respective
serial port itself), and press ENTER. The user will be presented with a
choice of every possible combination of output ports.
Use the arrow keys to move the cursor to the output port or combination of
output ports to be used with the input port, and press ENTER.
After the output ports have been selected, the OPTEDIT main screen will
return.
