Rear Panel
All installation and configuration devices for the RIO Bravo are located in the rear panel (see Figure 3):
Figure 3: RIO Bravo Rear Panel
J1 & J2 POWER: two connectors for feeding redundant power (+24 VDC) from SAS power supply.
J3 Dante PRIMARY & SECONDARY: dual RJ45 for connection to Dante AoIP network.
CONTROL LAN J4: for connection to your control network.
J5 1(L)/2(R) & J6 3(L)/4(R): two stereo 1/4” jacks for connection to monitoring devices. Note,TRS jacks in
parallel with RJ45 1-4: J5-1 (L) to J7-1; J5-2 (R) to J7-2; J6-1 (L) to J7-3; and J6-2 (R) to J7-4.
J7 1–8 ANALOG OUTPUTS: four RJ45 for connection to eight discrete analog outputs or four stereo. These
connectors also provide +12V DC that can power head phone amps. Note TRS jacks in parallel with RJ45 1-4:
J5-1 (L) to J7-1; J5-2 (R) to J7-2; J6-1 (L) to J7-3; and J6-2 (R) to J7-4.
J7 1–16 DIGITAL OUTPUTS: four RJ45 for connection to 16 discrete digital outputs or eight AES outputs
(4 AES outputs on first RJ45, 2 AES on next and 1 AES on two connectors). Digital Outputs 1-8 often used to
feed console meters, cue, talkback, and headphones.
J8 RELAYS: Two RJ45 for connection to a Timer (Relay 9=Stop, Relay 10=Run, Relay 11=Reset)
and a studio On Air light (Relay 12).
J9 GPIO 1 - 8: Eight RJ45 for connecting 8 relays out and logic in. Use these GPIO for reading external
switches, driving indicators, and other control functions in your studio. Relay on pins 1 & 2. Logic In close pin
7 to 8.
J10 SAS CONTROL PORTS 1 - 8: 2 RJ45 for connecting eight RS-485 control ports. You can connect a
console with up to 16 modules per RJ45 (up to 32 slots using both connectors).
J11 CONTROL PORTS 9 – 16: 8 RJ45 for connecting to eight RS-485 ports. Use these to connect any SAS
controller including console modules. You can connect up to 4 controllers per port.
A1 – A6 SLOT: for connecting up to six I/O plugin modules (sold separately). Available modules provide
16 discrete analog or digital channels. Figure 4: Model RBAI-16 provides 8 Stereo (16 Mono) Analog Inputs;
Model RBDI-16 provides 8 AES3 (16 Mono); Model RBAO-16 provides 8 Stereo (16 Mono) Analog Outputs:
and the RBDO-16 provides 8 AES3 (16 Mono) outputs.
