CONNECTION OF PRINTER TO DETECTOR

NOTES

1)

Many printers do not

require CTS, DSR or DCD to be at active levels.

However it is accepted good practice to connect these signals together as shown.

2)

The printer pin numbers shown are for an RS232 25-way D-type connector - if your

printer uses a 9 way D-type connector consult the printer manual for the correct pin numbers.

3)

These are the terminal numbers of the COM1 connectors on the P/S

Connection PCB within the Power Unit Enclosure.
