AGILE 5250 OPTIMA User’s Guide and ReferencePage 1-14
Connecting the Alternate Host(s)
The 5250 OPTIMA supports up to three alternate hosts. Each of these
alternate hosts may share the printers attached to the output ports with each
other and with the host system. Data received from these ports is sent to
the output ports on a first-come-first-served basis. No operator intervention
is required to switch to the alternate host ports  the OPTIMA does this
automatically.
The OPTIMAs PARALLEL IN ALT HOST port is dedicated for use as an
alternate host port. Each of the two serial ports, if not used as an output
port, may also be used as an alternate host port. If only one serial port is to
be used as an alternate host port, use SERIAL I/O PORT 0.

Connecting an Alternate Host via Parallel

The cable required to connect the PARALLEL IN ALT HOST port to an
alternate host device such as an IBM PC or compatible is available from
AGILE as an option.
To connect the PARALLEL IN ALT HOST port to an alternate host
device:
1. Insert one end of the AGILE parallel alternate host cable into the
connector on the rear of the alternate host device. Both ends of the
cable are the same, so either end may be used.
2. Tighten the thumbscrews until the connection is firm, but do not
overtighten.
