AVS-8764 User Manual (Iss. 03) Introduction • 1–1
Overview
The AVS-8764 AES/Analog Video Switch provides a convenient and economical solution when systems require switching of analog video or digital AES/EBU audio.
Each card has 4 inputs and two 4x1 crosspoints. Each output is available on two BNCs. The card can be configured for 7x1, 4x2, 4x1, Dual 2x1 or 2x1 operation.
Each switch is controlled by an optional control module (RMC-8120 or RMC-8120-1) or by GPI contact or logic level. All switching is done in the vertical interval based on composite sync switch timing, timed to an external analog reference. The AVS-8764 can use either of the two frame references that are distributed to all cards in the openGear frame. The appropriate switching line is automatically determined by the reference frame rate (50Hz or 59.94Hz). The last input selected for each output is stored in non-volatile memory for power failure protection.
LEDs are provided to indicate input and reference signal presence, and to show which input source is selected for each output.
Note
— Support for tri-level sync switch inputs is not implemented at this time.
The AVS-8764 is fully compliant with all openGear technical specifications and supports remote monitoring via the DashBoard Control System™ software.

3. Configure the behavior of SW1 by setting JP4 as follows:
• 4x1 — Select this option to have SW1 cycle through inputs 1 through 4.
• 2x1 — Select this option to have SW1 cycle between inputs 1 and 2.
4. Configure the behavior of SW2 as follows:
3–6 • User Controls AVS-8764 User Manual (Iss. 03)
• Set JP9 to NORMAL.
• Set JP4 as follows:
›
4x1 — Select this option to have SW2 cycle through inputs 1 through 4.
›
2x1 — Select this option to have SW2 cycle based on the JP10 settings.
• If JP4 is set to 2x1, set JP10 as follows:
›
INPUT 1&2 — Select this option to have SW2 cycle through inputs 1 and 2.
›
INPUT 3&4 — Select this option to have SW2 cycle through inputs 3 and 4.
This completes the procedure for configuring SW1 and SW2.
Auto Change Over (ACO) Mode
When the AVS-8764 is configured for Dual 2x1 mode, there is an option to enable the Auto
Change Over (ACO) mode. During ACO Mode, a Loss of Signal (LOS) on the primary input will cause the output to switch to the secondary input. Once the output is switched, the card will check the presence of the primary input to return. When the primary input has returned for 30 seconds, the output will switch back. DashBoard enables you to configure the trigger for the ACO
Mode when operating in Dual 2x1 mode. If you are operating in 4x2 or 4x1 modes, the ACO
Trigger is automatically set to Loss of Signal. For information on the available options for the
ACO Trigger, refer to the section “Remote Control Menus” on page 5-5.
7x1 Mode Setup
This section outlines how to configure the jumpers on the AVS-8764 cards for operating in 7x1 mode, and enabling the mode on the downstream card. Note that only the downstream, or Master, card is enabled for 7x1 operation.
For More Information...
• on operating in 7x1 mode, refer to the section “7x1 Mode” on page 4-4.
• for diagrams illustrating possible 7x1 configurations, refer to Figure 4.3 and Figure 4.4.
Setting the Jumpers
Use the following procedure to configure the jumpers on the AVS-8764 cards for 7x1 mode:
1. Set JP1 to SLAVE on the upstream AVS-8764 card.
2. Set JP1 to MASTER on the downstream AVS-8764 card.
3. Set JP3 to PANEL on both cards.
4. Set JP4 to 4x1 on both cards.
5. Set JP5 to 4 Button on both cards.
Enabling 7x1 Mode
Use the following procedure to enable 7x1 mode for the downstream, or Master, card:
1. In DashBoard, display the Device View of the AVS-8764 by double-clicking its status indicator in the Basic Tree View.
2. Select the Setup tab from the Device View.
3. To enable 7x1 mode, select the 7x1 Mode check box.
This completes the procedure for setting up your cards for 7x1 mode.
AVS-8764 User Manual (Iss. 03) User Controls • 3–7
Selecting the Timing
The DFR-8300 series frames accept two external analog references which are distributed to all the cards installed in the frame. Either of these references can be used to synchronize the
AVS-8764.
The AVS-8764 will switch on the vertical interval when provided with an analog reference. The switching line is determined via the frame rate (50Hz or 59.94Hz) and the data rate. The
AVS-8764 can switch without an analog reference, but the switch timing will be random.
Use the following procedure to configure the switch timing of the AVS-8764:
1. Set JP6 as follows:
• FRM 1 — Selects the source connected to the REF 1 port on the back of the frame.
This is the default setting.
• FRM 2 — Selects the source connected to the REF 2 port on the back of the frame.
This completes the procedure for configuring the switch timing of the AVS-8764.
3–8 • User Controls AVS-8764 User Manual (Iss. 03)
Clamp Setup
JP13 enables you to feed a reference voltage to the four input amps. The input amps use this reference voltage to provide a DC Restore that uses sync tip clamping. The DC Restore may be set for composite video, AES/EBU audio, or RGB video. This feature is not available for tri-level sync video signals.
Note
— JP13 has no effect if you are using balanced AES inputs.
Use the following procedure to set up the clamping feature:
1. Set JP13 as follows:
• VID — Select this option for analog composite video, component video, or RGB video with sync. This is the default setting.
• AES — Select this option for AES/EBU digital audio or the U, V, channels of component video.
• RGB — Select this option for RGB video without sync.
This completes the procedure for setting up the clamping feature.

Up to 10 cards can be controlled simultaneously by a single RCM-8120 control module (1 Master card, 9 Slave cards). Also, up to three control modules may be connected to a control bus. When multiple modules are connected to a control bus, selecting the active module is accomplished via a GPI connection on the back of each control module. Only one module can be active at a time, to avoid bus contention. Non-active modules will indicate the currently selected Output.
The control bus is a single coax cable. It originates at the Master card (BNC 1 for GPI 1, BNC 2 for GPI 2). The control bus provides both power and data communications to the remote modules.
Female T-connectors may be used to split the coax at each card or module to loop the control bus to the next module. Remote modules may also be connected together via audio/control cable such as Belden 1503A audio/control cable (22 AWG shielded pair).
Note
— GPI 1 (BNC 1) and GPI 2 (BNC 2) cannot be connected to the same control bus.
Remote modules may also be GPI controlled with closed contact or logic low (level or pulse).
Four GPI terminals are provided on the back of each control module, one for each input. For more information, refer to the documentation for your RCM-8120.
When operating the AVS-8764 with the control module, connecting multiple cards to the same bus allows you to switch multiple channels of SDI video, Analog video, AES, and Analog audio simultaneously.

7x1 Mode
When the AVS-8764 is configured for 7x1 mode, two four-button panels are connected together with the two 7x1 switches. Note that Panel 1 connects to GPI 1 on both AVS-8764 cards. The upstream switch will have one panel connected in slave mode and will listen for button presses and changes the outputs accordingly. The downstream switch will have both panels connected in master mode. When a button press is detected on the panel this connected to the upstream switch, the downstream switch will change to Input 1 which originates from the upstream switch. This switch is delayed for approximately 1-2 fields in order to allow the upstream switch time to make
the change. Refer to the section “7x1 Mode Setup” on page 3-7 for setup details.

Figure 4.5 Example of Signal Flow with Multiple Module Operation
To select which module is active, a GPI must short the module GPI. On the back of each module is a three-pin connector for the GPI. Shorting pins 1 and 2 together, or bringing pin 1 to a low logic level, will enable the module.
In installations where two modules are connected to a control bus, the RCS-8120 may be connected to the 2 remote modules to select which module is active. The RCS-8120 has two dual push button switches, so one RCS-8120 can control four RCM-8120 modules.
AVS-8764 User Manual (Iss. 03) Operation • 4–5
GPI Switch Operation
The following sections explain common configurations using GPI Level and GPI Edge controls.
When configured in 2x1 Mode, the AVS-8764 can be controlled by the RCS-8120 Remote
Control Module. This module has dual push-button switches for GPI triggering.
GPI Level Operation
In GPI Level Mode, the card can work in two ways, as a 4x1 switch or as a Dual 2x1 switch.
There are two GPI BNC connections (BNC 1 and BNC 2). The first input of each 2x1 switch is selected while the GPI input is open. A ground or low logic level will cause the second input to be selected.
GPIs are internally pulled up to +5 VDC. GPI shields can be tied together.
To control the card by GPI Level, use the following jumper configurations:
• JP3 — Set this jumper to GPI. Input selection to be controlled by GPI.
• JP11 — Set this jumper to LEVEL. Input selection to be determined via GPI levels on
BNCs 1 and 2.
4x1 GPI Operation
If the card is configured as a 4x1 switch, the GPIs are binary encoded, and Output 2 tracks Output
1. Input selection is as follows:

If the card is configured as a Dual 2x1 switch, Output 1 is controlled by GPI 1. Output 2 can be controlled independently by GPI 2, or can track Output 1. Input selection for Output 1 is as follows:
• GPI 1 Open — Input 1
• GPI 1 Short — Input 2

• GPI 2 (BNC 2) is not used
• Output 1 can select between Inputs 1 and 2
• Output 2 can be configured to select between

GPI Edge Operation
Edge triggering looks for negative going edge on the GPI input. The pulse used must be at least 3 fields in duration (about 50 ms). Since a pulse is used, the best way to control equipment is with one dedicated GPI per crosspoint. This way the controlling equipment can always set the
AVS-8764 to a known crosspoint. To do this, the AVS-8764 must be configured for edge triggered GPI mode as follows:
• JP3 — Set this jumper to GPI. The Input selection is controlled by GPI.
• JP11 — Set this jumper to EDGE. The Input selection is determined by high-to-low GPI transitions.
Since the AVS-8764 only has two GPI inputs, the card will only work in this mode when Switch
2 is set to Follow Switch 1 (JP9 is set to FOLLOW 1). A negative going edge on GPI 1 (BNC 1) will select the first input, and a negative going edge on GPI 2 (BNC 2) will select the second input.
In this mode, the AVS-8764 operates as a 2x1 switch with both outputs controlled by GPI transitions on GPI 1 and 2. Output 1 can select Input 1 or 2 by toggling the following on GPI 1 and GPI 2:
• Select Input 1 — Toggle GPI 1 low for 3 fields.
• Select input 2 — Toggle GPI 2 low for 3 fields.

Troubleshooting Checklist
Routine maintenance to this openGear product is not required. In the event of problems with your
AVS-8764, the following basic troubleshooting checklist may help identify the source of the problem. If the frame still does not appear to be working properly after checking all possible causes, please contact your openGear products distributor, or the Technical Support department at the numbers listed under the “Contact Us” section.
1. Visual Review — Performing a quick visual check may reveal many problems, such as connectors not properly seated or loose cables. Check the card, the frame, and any associated peripheral equipment for signs of trouble.
2. Power Check — Check the power indicator LED on the distribution frame front panel for the presence of power. If the power LED is not illuminated, verify that the power cable is connected to a power source and that power is available at the power main.
Confirm that the power supplies are fully seated in their slots. If the power LED is still not illuminated, replace the power supply with one that is verified to work.
3. Input Signal Status — Verify that source equipment is operating correctly and that a valid signal is being supplied.
4. Output Signal Path — Verify that destination equipment is operating correctly and receiving a valid signal.
5. Unit Exchange — Exchanging a suspect unit with a unit that is known to be working correctly is an efficient method for localizing problems to individual units.
Bootload Button
In the unlikely event of a complete card failure, you may be instructed by a Ross Technical
Support specialist to perform a complete software reload on the AVS-8764.
Use the following procedure to reload the software on a AVS-8764:
1. Eject the card from the frame.
2. Press and hold the Bootload button, while re-inserting the card into the frame.
3. Release the button.
• The PWR LED will flash green while the card is waiting for a new software load.
• If a new software load is not sent to the card within 60 seconds, the card will attempt to restart with its last operational software load.
• Software can be uploaded to the AVS-8764 via DashBoard.
This completes the procedure for reload the software on a AVS-8764.
