IN-DIRECT Connection using PC Network card LBB 3510/0

The DCN 2000 system offers two methods for connecting a central control PC to the DCN system: DIRECT and IN-DIRECT.

DIRECT connection (see FIG 10-16).Using this method, the built-in RS232 port located at the rear of the CCU (LBB 3500/15 and LBB 3500/35 only) is used to connect the CCU to a COM-port of the control PC. See also Chapter 5. DCN Control using Personal Computers.

IMPORTANT: When using the DIRECT connection method between the Control PC and the CCU, the central operator has NO facilities on the PC for using headphones or an intercom handset. Additional DCN units are then required to provide these functions.

IN-DIRECTconnection see FIG 10-17).Using this method, a Network card LBB 3510/00 (see Chapter 5.2) is installed in the central control PC. Using the cable supplied with the Network card LBB 3510/00, connect the 15-pole D-type connector to the 15-pole D-type socket located on the PC Network card, and connect the DCN 6-pole modular connector to the DCN trunk-line Cabling. Ensure the PC Network card is configured and set-up correctly.

IMPORTANT:

PCF 180

1.A ‘DIRECT’ connection is ‘MANDATORY’ when the control PC uses ‘‘Windows NT 4.0’, Windows 2000 or Windows XP Professional as the operating system.

2.When using ‘Windows 95 or Windows 98 both the ‘DIRECT’ or ‘INDIRECT’ method may be used, but NEVER at the same time.

3.When using the IN-DIRECT connection method, facilities are available on the PC Network card for using headphones or an intercom handset.
