DB-9 Pin Name Description (refers to PC) RJ12 Pin
3 TxD Serial Data Output 3
2 RxD Serial Data Input 4
4 DTR Handshaking Output 2
6 & 8 CTS & DSR Busy Input 5
5 SGND Signal Common 0V 6
The wake-up input (pin 2 of the RJ12) 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 behavior may be avoided by switching off the sleep period
timeout.
EMC STATEMENT
The DP-510 and DP-520 printers are fully EMC (Electro-Magnetic Compatibility) compliant and are CE marked
accordingly. A Declaration of Conformity, in accordance with the EMC Directive 89/336/EEC (and as amended) is
available on request.
EMC Caution
System EMC compliance remains the responsibility of the system designer. It is recommended that shielded cables
are used; grounding arrangements will depend on the application.
