2. Multi- CCU System (FIG 10-22)

A null-modem RS-232 cable is used to connect the ‘Master CCU PC’ to the remote controller. The maximum cable length between the ‘Master CCU PC’ and the ‘Remote controller’ should not exceed 5 m (16.4 ft.). Where longer distances are required an ‘interface unit’ should be used to ensure correct transmission. See also Chapter 5.. DCN Control using Personal Computers

OPEN INTERFACE	PC dedicated for Multi-CCU’s
Remote PC	UPS (Uninterrupted Power Supply)
	recommended
	Multi-CCU Software LBB 3586
	and OS.2

NOTES:

1.The COM-port settings for a Multi-CCU system can be changed. Refer to the ‘ ‘Readme.txt’ file associated with the LBB 3586 Multi-CCU software package.

2.The RS232 COM-port on the slave CCU’s is disabled when used in a multi-CCU system

3.The communication protocol and a higher baud-rate for the serial COM-port can be adjusted as necessary (see Chapter 4.6 and Chapter 5.7).

10.9.2Typical examples using the Remote Controller

1. Assigning Microphones to push-button on the remote controller

In order to assign microphones to push-button on the remote controller panel, a push-button should first be assigned for switching the remote controller between the ‘Installation and Operational’ mode. To assign push-button to microphones, the remote controller should be switched to the ‘installation’ mode. Once in the installation mode, press the microphone button of the unit in the hall to be assigned, and then press its corresponding push-button (i.e. for microphone 2 press the push-button marked 2 etc..) and so on till all microphones have been assigned.

2.Assigning Microphone Management Modes and No. of active microphones.

Using the RS-232 capability the functions of the CCU can be simulated on the remote controller - for example: ‘Active Micros ( the number of microphones which can be activated simultaneously) can be selected, and the ‘Operation’ mode (microphone operational modes: ‘Open’, ‘Override’ and ‘Voice’) can also be selected.
