COMBINED DATA/CHARGER ADAPTOR CABLE
A data cable suitable for connecting the Ap1300 to a standard PC is available (ASL Product Code
AP1300-D9). This cable features an integrated charger jack socket in the housing of the D-9 plug.
For trickle charging, the charger may optionally be connected directly into the Ap1300 charger Jack
Socket, or indirectly into the Jack Socket in the data cable, thus giving the maximum system wiring
flexibility. It is recommended to use the internal socket when fast charging. The details for the
charger jack socket in the D-9 plug are the same as for the internal socket in the printer.
The connections to a standard PC COM port are as follows:

The wake-up input (pin 2 of the RJ-12) can be driven by a normal RS-232 handshaking output and
activates the printer when a positive voltage ('space' condition) is asserted. Connecting it to the PC
DTR signal wakes the printer when the COM port is 'opened'. It may alternatively be tied to a positive
voltage in the range +3V -> +12V to keep the printer awake permanently. In this case, the printer will
'attempt' to go to sleep if the normal inactivity time-out elapses, but will merely reset and then re-start.
This behaviour may be avoided by switching off the sleep period timeout.
9.5 EMC
STATEMENT
The Ap1300 is fully EMC (Electro-Magnetic Compatibility) compliant and is CE marked accordingly. A
Declaration of Conformity, in accordance with the EMC Directive 89/336/EEC (and as amended) is
available from Able Systems on request.
9.6 EMC
Caution
System EMC compliance remains the responsibility of the system designer. It is recommended that
screened cables are used; earthing arrangements will depend on the application. Further advice is
available from Able Systems on request.
