Press the Page down key again.
The display will step to the 1
st
page of serial port configuration, port address and baud rate.
------------------------------------------
| PORT SET|TX ADDRESS|RX ADDRESS|BAUD RATE |
| port|1=01 2=01|1=01 2=01|1=03 2=03 |
------------------------------------------
On both ports the TX and RX addresses are independently set. In most applications both the TX
and RX are required to be set to the same address. This address only allows data intended for the
BVR20 to be processed, thus identifying an individual BVR20 when several (maximum 8) are
connected to a BVAMC control microphone.
If only 1 BVR20 is connected to a BVAMC, the address, both TX and RX is set to 01.
If 2 are connected, 1 of the BVR20 is set to 01 and the other is set to 02 and so on for the
maximum of 8.
Port 1 serves Fire microphone 2 on audio input 2 and port 2 serves Fire microphone 4 on audio
input 4.
To change an address, move the cursor until it flashes beneath the required window and enter
address 1-8.
The Baud rates for both ports are independently set to correspond with the BVAMC DIL switch
settings as shown below.

Press the Page down key again.
The display steps to the 2
nd
page of serial port 1 configuration, BVAMC zone positions 1-10.
------------------------------------------
| PORT 1 out|01|02|03|04|05|06|07|08|09|10 |
| panel zone|01|02|03|04|05|06|07|08|09|10 |
------------------------------------------
Any of the 10 outputs 1-10 can be selected individually or collectively to appear as any single zone
on the BVAMC fire microphone 2.
To change a zone selection, move the cursor along until it flashes beneath the required output
window.
Press 0 if this output is not required to appear on the BVAMC.
If the zone required is between 1-9, enter it directly using the numbered keys, or using the + or –
keys step to the zone required between 00 and 63.
