4.7 Setup Video/CG > Video/Character Generator Configuration
Select the Setup > Video/CG radio button under the Setup menu to access the web pages for controlling operation of
external and internal character generation.
In Broadcast mode, there are six tabbed sub-pages on the Setup Main Serial CG Options page: Video Out, Main Serial
and USB Serial 1 through 4 for up to four expansion USB serial ports. Broadcast mode DASDEC II's support up to five (5)
simultaneous serial ports (one main RS232 port on the back panel, and 1 to 4 expansion RS232 ports provided via a USB
port expander), each running a different character generator protocol.
Non-broadcast mode DASDEC II's only have a single page interface that combines the Video Output options with the
Main Serial port options. Non-broadcast mode DASDEC II's support only the main serial port.
The DASDEC II can also optionally provide native analog NTSC composite video output. Video/CG behavior is configured
only on this page and applies to both Decoder Alert Forwarding and Encoder Alert Origination.
Changes to each Setup Video page require submitting modifications using the
Button. You may wish to
refer to Chapter 3.3.4.2 How to Make Changes and Update for details on making changes to pages with this button.
Start with the Main Serial page.
4.7.1 Main Serial
The Main Serial sub-page has three sections: Serial Port Character Generator Configuration; selected CG
Attribute Settings; and FIPS and EAS Codes filter configuration. Information in each section is reviewed below.
1. Serial Port Character Generator Configuration
The radio selection buttons show the Character Generator (CG) used when a decoded alert is forwarded or
encoded (or no CG). There are eight supported character generator protocols: Monroe Envoy, Monroe
CEMS-0500/1000, Standard TFT, Chyron CODI, VDS 840, Sage Generic CG, DecadeNet XBOB, and
BetaBrite LED sign. Of these, the Monroe CEMS-0500/1000, VDS 840, and DecadeNet XBOB require a
DASDEC II TV license. The Chyron CODI interface requires both a DASDEC II TV and a Plus Package
license.
Choose the appropriate protocol for the connected serial device and check that option. The CG should be
connected to the server serial port (on the back panel) using the correct serial cable (TFT, CODI, VDS use
NULL modem cable, Monroe CGs use straight through cable, SAGE Generic depends on specific CG,
usually a straight through cable). Use SAGE Generic for Evertz MediaKeyer and Logo Inserters as well as
for Miranda Imagestore Cgs. Most of the character generator protocols present some further configuration
options. Some, like Chyron CODI and VDS840 present direct control of alert repetition, font colors, number
of crawl loops, etc. Experiment with these settings to get the desired behavior. The CODI protocol also
presents options for generating test patterns. Most CG's also can be configured to run repetitions of the
video output during an alert. The available CG's and protocols are described in Chapter 9 - DASDEC II
Peripherals.
2. CG Attribute Settings
The options displayed here depends on the selected CG protocol. The screenshot shows the SAGE Generic
CG has been chosen. So, for SAGE Generic, a user would choose the correct settings for Serial Port Baud
Rate, Serial Port Flow Control, Iterations; and Repeat Alert Video Display. There is also a checkbox to
toggle the Throttle down serial port write speed from Enabled to Disabled.
