Frequently Asked Questions
Q: What does the RC-SDA™ do?
A: This module provides dual output paths from the digital video source, plus
provides 2 independent RS232 control inputs to the attached camera. The system
is optimized for use with Poly/Polycom camera output and camera input
requirements.
Q: Why does the RC-SDA™ have 2 HDMI outputs?
A: The RC-SDA™ makes 2 “copies” of the digital video signal input and sends
those copies to the HDMI outputs. The Poly/Polycom codec should always be
connected to Output 1 to ensure compatibility. Output 2 can be connected to an
external monitor or HDMI to USB video converter for soft codec applications.
Q: Why are there two serial inputs and only one output?
A: The RC-SDA™ provides an RS232 port to connect to an RC4-HE™ (Head-End
Receiver) or RC7-HE™ (Head-End Receiver) allowing serial control of an
attached camera or camera system. There is a “pass-through” RS232 input
intended to come from a host codec camera control path.
There is also a “direct” RS232 input intended to come from a serial control
system (e.g., Extron, Crestron, AMX) to control the attached camera directly
(camera control-code provided by others).
Q: Does the RC-SDA™ support far-end camera-control (FECC)?
A: Yes, when used with a Poly/Polycom codec as the primary host, the FECC is
supported as a “pass-through” RS232 control channel to the camera. In this
way, a control-system (specifically, Extron, Crestron, and AMX) may be used to
directly control the camera, yet the control path from the codec to camera is
not compromised.
Q: I’m not using a Poly/Polycom codec and my EagleEye Director 2 (EED2)
goes to sleep after 3 minutes. What can I do?
A: RC-SDA™ has an intrinsic “keep awake” mode (called Director-II mode) for
the EED2. It allows for a dual-use application of the camera system, such as
transitioning to a soft-codec environment or using the EED2 with a video
switcher front-end to a video processor. Switch 5 should be in the ON (UP)
position and switch 6 in the ON (UP) position to enable this mode.
Q: I have changed the DIP switch settings, but nothing changes in the RC-
SDA™. What’s wrong?
A: The RC-SDA™ “reads” the DIP switch setting during the power-up
initialization and at no other time. To change the RC-SDA™ mode of operation,
one should remove power, change the switch setting, and then re-apply power.
Q: My control system doesn’t act upon the attached Poly/Polycom EagleEye IV
camera.
What’s wrong?
A: The control system communicating with the Poly/Polycom camera must use the
appropriate control codes for that camera. Poly/Polycom uses a special
communication language that is embedded in locked modules provided by AMX,
Crestron, and Extron respectively. Also, make sure the control system’s RS232
port is set to 9600 8/E/1, or there will be no communications to the
Poly/Polycom camera.
Q: What is the Micro SD slot for?
A: The Micro SD slot on the RC-SDA™ allows for field upgradable firmware and
diagnostics.
Q: What do the DIP switches do?
A: The following chart shows the functions of the 8 position DIP switch:
| Switch | Function | OFF | ON |
|---|---|---|---|
| 1 | Reserved for future use | ||
| 2 | 3-Pin (RS232) Mode | 9600, 8/N/1 (VISCA) | 9600, 8/E/1 (POLY) |
| 3 | 3-Pin Listen Mode | RS232 responses from the camera are Disabled | RS232 |
responses from the camera are Enabled
4| Codec DB9 (RS232) Mode| 9600, 8/N/1 (VISCA)| 9600, 8/E/1 (POLY)
5| Camera DB9 (RS232) Mode| 9600, 8/N/1 (VISCA)| 9600, 8/E/1 (POLY)
6| Poly Director-II Mode| Disabled| “Keep Alive” Enabled
7| Reserved for future use
8| Reserved for future use
Q: What do the S1 and S2 switches do?
A: S1 and S2 are momentary pushbuttons on the front of the RC-SDA™.
S1 triggers a camera reset and re-initializes the tracking mode of the EED2
when the RCSDA™ is in Director-II mode.
S1 is also used to initiate firmware upgrades and write log files to the Micro
SD card. Refer to the “RC-SDA (2021) Firmware/Log Guide” at
www.soundcontrol.net for details.
S2 is reserved for future use.
Q: I’m sharing the EED2 with a Poly/Polycom codec and a soft codec PC
application. Why does my EED2 camera keep shutting off and turning around
backwards?
A: Your Poly/Polycom codec may have a sleep timer set which causes the EED2 to
sleep as well. You should turn off the sleep time in the codec web interface.
