Attach twinax cables
Attach the twinax cable from the host
computer to the "Smart T" connected to
the printer earlier.
1
If there is an up cable device
connected to the twinax cable (from
the host), the twinax cable must
originate from the "OUT" connector of
that device. The other end of this cable
attaches to either side of the "Smart T"
connected to the printer.
2
If this printer is the last or only device
on the twinax line, the twinax cable
attaches to either side of the "Smart T"
connected to the printer.
3
If there is a down cable device,
connect the other twinax cable to
either side of the "Smart T".
Address switch
Before testing, do the following:
1
Verify that the printer address matches
the one set up on your host system.
The I/O address should be unique on
the twinax line. BE CERTAIN THAT
NO ADDRESS ON THE LINE IS
DUPLICATED!!!
To set the printer address, rotate the
address switch, on the I/O, to the
number that corresponds to the
address setting for your environment.
This address should be some number
between 0 and 6.
2
Verify that the address matches the
one set up on your host system
configuration.
