Unit 3: Installation
S8400 Series Operator Manual
3-20 PN: 9001160B
EXTERNAL SIGNAL
The external signal interface is designed to connect the printer to an applicator. Proceed to the printer’s Advanced
Mode for various setup activities related to the external signal.
There are two connector types available for the external signal interface, one with a 14-pin connector and the other
with a 25-pin connector.
SPECIFICATIONS
Signal Level High: +2.4 to +5.0V, Low: +0.0 to +0.4V
Issuing/Reissuing EXT signal Enable/Disable in the Advanced Mode.
Switching EXT signal Switching jumper connector to enable +24V output by 24V and 27V power supplies.
When using 24V power supply: Short IN 24V side by jumper connector
When using 27V power supply: Short IN 27V side by jumper connector.
Signal Types Type I Print end signal (PREND) is “low” before printing labels, “high” after
completion of print, and “low” 20 miliseconds later.
Type II Print end signal (PREND) is “high” before printing labels, “low” after
completion of print, and “high” 20 miliseconds later.
Type III Print end signal (PREND) is “low” before printing labels, “high” from start to
end of print, and “low” upon completion of print.
Type IV Print end signal (PREND) is “high” before printing labels, “low” from start to
end of print, and “high” upon completion of print.
