The connections to a standard PC COM port are as follows:

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 LCM20 and LCM25 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.
