5.1.5. Connecting the GPI Tally Control
The EAS decoders give out a tally control to indicate when an EAS alert message is being broadcast.
This tally output must be connected to one of the GPI inputs on the 9625LG Series Keyer to signal it to
'duck insert' the emergency audio into the program audio. For the sake of simplicity in this description
connect the tally output from the decoder to the GPI A input on the 9625LG Series Keyer. (See Table
2-4 for a pinout of the GPIO connector on the keyer unit.)

CONFIGURING THE 9625LG SERIES KEYER FOR EAS
5.2.1. Configuring the Serial Port
In order for the EAS decoder to communicate to the 9625LG Series Keyer you must configure the
SERIAL CONTROL C, COM D port or COM E virtual port for the correct protocol and baud rate. The
SERIAL CONTROL C, COM D or COM E (net) menu item on the General menu is used to accomplish
this. Set this menu item to EAS CG in order for the EAS decoder to communicate to the 9625LG
Series Keyer. See section 3.6.5 for information on setting the serial port protocol.
5.2.2. Configuring the GPI Input
In order to use the GPI to insert the EAS audio you must configure the GPI A input as shown in Table
5-2. See section 3.8.1 for information on configuring the GPI inputs.

5.2.3. Configuring the EAS Controls
The EAS menu items are used to configure the EAS crawl position, size, and colours. See section 3.9
for a complete description of these menu items. The brief descriptions of the menu items will guide you
in setting up the unit quickly.
Vert Position (V):
The default value should be adequate but you need to ensure that the messages
fall within the safe area of the video display so that the entire message is legible once the
message is broadcast.
FontHei:
Sets the size of the Scrolling text in video lines.
Rate:
Sets the speed of the scrolling text message in pixels per field. Rate 1 is the slowest
possible scrolling speed and 32 is the fastest scrolling speed. If you adjust the font size you
will have to adjust the scroll rate. The smaller the font size the slower you will have to scroll
the text box.
