For Setting up with a Digital Alert Systems Dasdec-2
The Digital Alert Systems Dasdec-2 connects to the MC1-MK via serial RS-232 or the Comtrol®
DeviceMaster® over Ethernet. For information on configuring a Comtrol DeviceMaster, refer to the
openGear DeviceMaster Setup Sheet (Ross Part Number: MC1MKDR-100).
The Digital Alert Systems Dasdec-2 requires the following connections to the MC1-MK:
1. Communications connection (Serial or TCP/IP via Comtrol DeviceMaster) to provide EAS crawl text.
2. EAS Voice Over connection using an GPI to the MC1-MK.
3. Analog or AES audio connection to provide alert tones and/or TTS.
Overview
Figure 1 outlines the required physical connections.
1. Connect the Comtrol DeviceMaster to your facility network.
2. Connect the Serial port on the Comtrol DeviceMaster to the Serial port on the Digital Alert Systems
Dasdec-2.
3. Connect the audio output from the Digital Alert Systems Dasdec-2 to an audio port on the
MUX-8258. Note that Figure 1 shows an MUX-8258-C.
4. Connect a GPIO port on the MC1-MK to the Digital Alert Systems Dasdec-2.
5. Connect the key alpha video source to the SDI IN BNC on the MUX-8258.

Connecting the Comtrol DeviceMaster to the Dasdec-2
The Digital Alert Systems Dasdec-2 connects to the Comtrol DeviceMaster via the RS-232 serial port on
the Dasdec-2 and an available serial port on the Comtrol DeviceMaster.
You will need a DB-9 female to DB-9 female null modem cable. Ross Video does not supply this
cable.
Refer to Table 1 for the required Serial RS-232 pinout designations.
Refer to Table 2 for pinout designations on each serial port.
Proceed to connect the MC1-MK to the Digital Alert Systems Dasdec-2.
Connecting the Dasdec-2 to the MC1-MK
There are two cabling options for establishing communications between the MC1-MK and the Digital
Alert Systems Dasdec-2: Serial or TCP/IP. Both methods are described in this section.
Serial Connection
The Digital Alert Systems Dasdec-2 connects to the MC1-MK via an available serial port (RS-232) on the
Dasdec-2 and the SERIAL port (RJ45) on the MC1-MK rear module.
You will need a DB-9 female to RJ45 cable. Ross Video does not supply this cable.

TCP/IP Connection via a Comtrol DeviceMaster
The Digital Alert Systems Dasdec-2 connects to the MC1-MK over TCP/IP using a Comtrol
DeviceMaster.
You will need a DB-9 female to DB-9 female null modem cable. Ross Video does not supply this
cable.
1. Connect the Digital Alert Systems Dasdec-2 to the Comtrol DeviceMaster via the RS-232 serial port
on the Dasdec-2 and an available serial port on the Comtrol DeviceMaster.
2. Connect the MC1-MK to the same network as the Comtrol DeviceMaster.
EAS Audio Voice Over Connection
This section outlines how to connect the Digital Alert Systems Dasdec-2 to the MC1-MK for an EAS
audio voice over setup.
You will need to:
1. Connect the GPO (RELAY) port on the Digital Alert Systems Dasdec-2 to the GPI 1 port on the
MC1-MK rear module. Refer to the MC1-MK Installation Guide for GPIO pinout information.
Ross Video does not supply this cable.
2. Ensure that the Dasdec-2 GPO (RELAY) port is configured for PTT Relay programming.
3. Configure the GPO (RELAY) port on the Dasdec-2 for EAS Audio Playout.
MC1-MK Audio Connections
When connecting the MC1-MK-MK to the Digital Alert Systems Dasdec-2, you will also need one of the
following openGear cards for audio:
• AES audio — an MUX-8258-A is required
• Analog audio — an MUX-8258-4C or MUX-8258-8C is required
Both methods are outlined in this section.
For More Information on...
• Dasdec-2 audio pinouts, refer to its user documentation.
AES Audio
The Digital Alert Systems Dasdec-2, when equipped with AES audio, provides AES outputs on a DB9
connector. A breakout cable is required to adapt these AES output for the MUX-8258-A.
Ross Video does not supply these cables.
1. Connect the breakout cable from the AES AUDIO port on the Dasdec-2 to the MUX-8258-A as
shown in Figure 2.
2. Ensure that Dasdec-2 Audio Output is set to 48000 samples/second.
Analog Audio
The Dasdec-2 connects to the MUX-8258-C via two audio ports. You will need two XLR cables. Each
cable must include an XLR-3F 3-pin female connector (to connect to the Dasdec-2) on one end, and
one WECO™ 3-pin connector on the other (to connect to the MUX-8258-C rear module). Refer to the
MUX-8258 User Manual for rear module pinout details.
Ross Video does not supply these cables.

Customizing the EAS Text Overlay
The MC1-MK provides an overlay that displays an EAS horizontal text crawl in real time. The overlay is
automatically loaded into Logo 4 and associated with Keyer 4 of the MC1-MK. When EAS is enabled, do
not use Logo 4 and Keyer 4 for any other purpose.
To customize the EAS text overlay
1. Select the Configuration node to display the interface in the right-half of DashBoard.
2. Select the SAGE EAS Setup tab.
If the EAS Setup tab is unavailable, verify that you have correctly installed your EAS device and it is
communicating with the MC1-MK.
3. From the Preview area, select the type of event message you want to customize. The following
will occur once you select a category button:
For normal EAS operation, set the Preview to OFF.
• The EAS Setup tab settings display the stored values for the selected category.
• A test EAS message automatically displays on the Preset bus (the Key 4 button is now lit on the
Preset bus). This enables you to verify your changes to the EAS text overlay.
4. Use the % Top Row option to adjust the vertical position of the EAS text overlay. Note that this
setting is not applicable to the Emergency Alert (High Priority) categories as these messages are
fixed to the top of the screen.
5. Use the Text Size option to adjust the font size of the text overlay from smallest (1) to largest (10).
Note that actual text size is dependent on the video format.
6. Select a text color and/or background color for the text overlay using the provided fields. The EAS
Text Attributes field reports an error when the text color and the background color match.
When using very long EAS messages, the MC1-MK may use a smaller font size and/or may disable
transparency. The exact length depends on the widths of each font character.
7. To apply a drop shadow to the text overlay, select the Drop Shadow box.
8. Use the Pan Speed slider to set the speed of the EAS text crawl across the screen. The default is 2.
9. Use the Repeat Count to set the number of times to display the entire text crawl before taking it
off air. The default is 2.
10. Repeat for each message category you want to configure.
