5. Module status
The status of the module can be monitored in two ways.
1. GYDA System Controller (optional).
2. LED’s at the front of the sub-rack.
The LED’s are mounted on the module itself, whereas the GYDA System Controller is a separate module
which gives detailed information on the card status. The functions of the LED’s are described on the next
page. The GYDA controller is described in a separate user manual. This manual is available on our web
site: http://www.network-electronics.com/
5.1 GPI ALARM –Module Status Outputs
These outputs can be used for wiring up alarms for third party control systems. The GPI outputs are open
collector outputs, sinking to ground when an alarm is triggered. The GPI connector is shown in Figure 4 .
Electrical Maximums for GPI outputs
Max current: 100mA
Max voltage: 30V

No video input detected
Pin 2 Open Collector
LOCK Module not gen-locked to video input Pin 3 Open Collector
Ground 0 volt pin Pin 8 0V.

5.2 Front Panel -Status Monitoring
The status of the module can be easily monitored visually by the LED’s at the front of the module. The
LED’s are visible through the front panel as shown in Figure 5 below.
(Text not printed on the front panel).
Figure 5 -Front panel indicator for DAC-PAL-M
The DAC-PAL-Mhas 3 LED’s each showing status information. The position of the different LED’s is
shown in Figure 5 .

memory fault
CD No SDI video input

6. Interface with GYDA and RS-422 command set
All commands follow the flashlink protocol and can be used for direct control access to the module. The
control system can either be a GYDA or a third-party control system with integrated flashlink protocol.
The module can also be manually controlled with a VT100 compatible terminal program.
The protocol can be found on our web page; http://www.network-electronics.com
6.1 DAC-PAL-MCommand table
Command Response Comment
?Yes The “Hello” command.
info Yes Gives back the card state.
Pedestal on “OK” Pedestal is present.
Pedestal off “OK” Pedestal is not present.
eget [0xHH] Yes Get a value from a numbered eeprom register.
eset [0xHH] [0xHH] “OK” Set a value to a numbered eeprom register.
get [0xHH] Yes Get a value from a numbered register.
set [0xHH] [0xHH] “OK” Set a value to a numbered register.
Table 2 -All commands available to the user
6.2 The “?” command
According to the Flashlink-protocol, no card can use the RS422-bus before it has been activated with the
“?” (hello) command. The response from DAC-PAL-Mwill be:
xxxxDAC-PAL-M\
PIC sw rev X.X.X\
Protocol ver X.X
Here xxxx denotes the source and destination rack and slot coordinates, while Xrepresents a version
number. As of primo November 2004, these revisions would be:
xxxxDAC-PAL-M\
PIC sw rev 1.0.0\
Protocol ver 1.0
6.3 The “info” command
This command report the entire state of the card. An example:
xxxxLocked 50Hz\
Pedestal on

Locked 50Hz
Locked to 625 lines 50 Hz.
Locked 60Hz
Locked to 525 lines 60 Hz.
Digital input.
Not locked
Not locked, output muted
Pedestal on
Pedestal is present when locked to 525.
Pedestal Pedestal off Pedestal is not present when locked to 525.
Table 3: The info command broken up in components.
The “info” command is composed by many minor lines, fully specified in Table 3. In general, when a
condition is normal, it is not reported. For instance, pedestal is reported when locked to 50Hz, even tough
the setting has no effect on the video.
6.4 Pedestal command.
Command to turn on/off the Pedestal is straightforward text, see Table 2 .
6.5 get, set, eget and eset.
These commands are for internal factory use. The end-user should avoid these commands.
