1. General

The flashlink DAC-PAL-M is a high-quality SD distribution amplifier with 3 x SD digital and 3 x
composite analogue outputs. The SDI outputs are compliant to SMPTE 259M, and the composite
analogue outputs are PAL / PAL-M compatible.

DAC-PAL-M user monitoring can be performed via the GYDA control interface.
The DAC-PAL-M is designed for all distribution and monitoring purposes in studio, duplication and

Broadcast applications.

3. Connector module

The DAC-PAL-M has a dedicated connector module: DAC-MON-C1. This module is mounted at the rear
of the sub-rack. The module is shown in Figure 2 .

Figure 2 - DAC-MON-C1 connector module.

3.1 Correspondence of connectors and signals

The DAC-MON-C1 connector module has 7 BNC's:

3.2 Mounting the connector module

The details of how the connector module is mounted, is found in the user manual for the sub-rack frame
FR-2RU-10-2.

4. Configuration and Setup

Figure 3 - DAC-PAL-M simplified silkscreen.

The DAC-PAL-M card has no direct user settings available with DIP switches. Refer to the GYDA
Interface for possible user settings with the card.

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://nevion.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

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-M has 3 LED’s each showing status information. The position of the different LED’s is
shown in Figure 5 .

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://nevion.com

6.1 DAC-PAL-M Command 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-M will 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 X represents 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

Status of

Status string

Comment

Digital input.
Locked 50Hz

Locked to 625 lines 50 Hz.

Locked 60Hz

Locked to 525 lines 60 Hz.

Not locked

Not locked, output muted

Pedestal
Pedestal on

Pedestal is present when locked to 525.

Pedestal off

Pedestal is not present when locked to 525.

Table 3: The info command broken up in components.

DAC-PAL-M Rev. C

nevion.com | 11

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.
