CONNECTOR PINOUTS

J1 Pinouts
This 3-way power connector has the following pinouts:
Pin Assignment
Pin 1 Power Ground
Pin 2 Vmech (DC Power In)
Pin 3 Power Ground
Caution - Reversing the power input connections, even momentarily, can cause irrevocable
damage to the Ap1200.
N.B. Previous versions of the Ap1200 featured a 2-way power connector (Molex Part No: 26-60-4020)
A 2-way mating part which was wired for an old-style Ap1200 may be used with the new 3-way
connector, but extreme care must be taken to ensure correct connections are made.
J2 Pinouts
This 6-way data connector on the standard Ap1200 has the following pinouts:
Pin Name
Pin 1 SGND
Pin 2 RxD
Pin 3 BUSY
Pin 4 TxD
Pin 5 N/C
Pin 6 RESET

POWER SUPPLY REQUIREMENT

The DC power should be supplied between +4.75V DC and +8.5V DC. For best printing use between
+ 5V DC and +7.5V DC. Do not go above +8.5V DC.
Average current during printing is normally around 2A. Peak current may be up to 10A. We
recommend a 3A power supply, although a higher specification may be necessary for some
applications. Avoid voltage drops by taking care over wiring and connections. Lower currents may be
accomodated via the software Power Save mode (refer to the Programmers Guide for details).
N.B. Do not interrupt, reverse or reduce the voltage or damage will occur.
5.5

EXTERNAL RESET

An external reset input is provided on the standard Ap1200. This should be left unconnected or
connected to SGND if not used. To reset the printer, between +2V and +25V should be applied.
