6. Adapter cables
Even though it is not recommended, (wrong impedance
cable, non-adapted connectors, different electrical
specifications etc. which can lead to electromagnetic
compatibility problems and audible interference), it is
possible to transport command signals through a
microphone modulation cable or a multicore. It is quite
useful when making adjustments in a fixed installation, but
should be avoided in a touring environment due to the risk
of high level reproduction of command signals through
“diaphony” (?)
In this case we recommend the cabling solution illustrated
below:
The easiest method that doesn’t require [pince a sertir –
pliers?] is to use a 1m length of RS232 or CAT5/RJ45
Ethercon cable and to redo the connections by soldering
on two XLRs

7. Alternative Adapters
ATEN UC 232 A
MOXA NPORT DE 311
Not all USB, RS232, RS485, Ethernet or wifi adapters are
compatible with BvNet. Below are the ones we have tested
and can recommend.
USB/RS232
We recommend the “AUSB” ATEN UC 232 A adapter from
APG France
Serial/Ethernet
Most serial/Ethernet adapters with a Virtual Coms port are
compatible. We tested the MOXA NPort Express DE-311.
To connect to a single DMS26, or a BVNETADAPT (with
external power supply) via RS232, configure the MOXA
device as follows: SW1 – off; SW2 – off; SW3 – off
For a direct connection via RS485 (not recommended),
configure the device as follows: SW1 – off; SW2 – off; SW3 –
on.
As with all Ethernet connections, problems may occur with
the use of a firewall, in which case the firewall should either
be deactivated, or the adapter’s IP address needs to be
listed as a “trusted site” within the firewall.
