A-Control Specifications
The specifications below can be used to set up control systems to remotely
send commands to the A‑16R Personal Mixer via its A‑Control jack.
Physical Connections
The A‑Control interface on the A‑16R and A‑16CS is an RJ45 connector.
Cabling between the devices is standard Cat‑5e cable with a maximum
distance of 60m/200ft.
Electrical Connections
The A‑Control interface uses the RS‑422 asynchronous serial protocol for
information exchange. The A 16R also provides remote power to the remote
control unit. Electrical wiring of the Cat‑5e cable between the Host (A‑16R)
and the Controller (A‑16CS) is specified in the following table:
Wire
Number
Function
1 RS‑422 Data: Host Out to Controller In (Host Tx + )
2 RS‑422 Data: Host Out to Controller In (Host Tx ‑ )
3 RS‑422 Data: Controller Out to Host In (Host Rx + )
6 RS‑422 Data: Controller Out to Host In (Host Rx ‑ )
4 / 5 Ground
7 / 8 Remote Power: +18 to +30 VDC Unregulated / 40mA max
(+24 volts nominal for A‑16CS)
Note that the act of switching the A‑16R Local/Remote switch to the R
emote
position will supply power and ground down the A‑Control cable to the
Controller.
