7.3.2
Chaining Cable (48-0083) Connection:
The chaining cable is used to interconnect two or
more units when chained operation is desired. This cable is shown in Figure 7-10. To
chain units:
1. The printer cable is connected to the
RS232
connector on the first unit (as
described in the preceding sub-section).
2. The 9-pin connector of the chaining cable is connected to the
AUX
connector on the
unit.
3. The 25-pin connector of the chaining cable is connected to the
RS232
connector of
the next unit.
4. Steps 2 and 3 are repeated with additional chaining cables for each additional unit
to be chained. Up to 15 units may be chained.
7.3.3
Chained Unit Addressing Command:
After units are chained, units can be individually
controlled by
RS232
commands from one terminal, and units output their
AUTO PRINT
reports to that terminal. The addressing command must precede all other commands to
the unit. The command is:
!u
where "u" =
A
for the first unit and
B
,
C
,
D
, ...
O
for additional units.
The RS232 commands described in 7.1 can then follow this command.
