In this chapter you will learn how to connect a CD-16,CD-8 microphone to a VACIE system as well as
how to connect external microphone, external speaker and telephone handset.
7.1. RS485 through CAT5
The CD-16,CD-8 uses RS485 protocol over shielded CAT5 to transport data from the microphone to
the VACIE.
The theoretical maximum distance for RS485 is 1000 meters. However, as the CD-16,CD-8 is
powered via the VACIE system a maximum of 200 meters is recommended without the use of an
external power supply.
The CD-16,CD-8 microphone is supplied with a 10 to 8 pins CAT5 cable converter.
When using an external power supply, make sure that the Junction Box power switch is set to
EXT.PWR. and the MASTER-SLAVE switch to the MASTER position.
