2x1 HD/SD-SDI changeover
HDSDI-CHO-2x1-PB
2x1 HD/SD-SDI change over with passive bypass
1 Product overview
1.1 Product description
Figure 1: HDSDI-CHO-2x1(-PB) functional overview
The Flashlink HDSDI-CHO-2x1 is a serial digital video 2x1 change-over module providing high performance line protection for various signal formats from 1Mbps up to 1485Mbps. The unit can be configured to perform cable equalizing and re-clocking of SMPTE 292M, SMPTE 259M and DVB-ASI signal formats. The switching criteria can be selected to be based on loss of input signal or loss of lock (re-clocker). The switch can either be latching or non­latching (in loss of lock mode, only latching switch is available). It is also possible to control the switch with GPI inputs, with the GYDA system controller or with the open protocol RS422 interface.
The two inputs typically provide automatic cable equalizers for up to 250 meters of cable (Belden 8281A at 270Mbps) with a 2 x 1 switch in front of a re-clocker with 4 outputs. The re­clocker supports the bit-rates; 143, 177, 270, 360, 540 and 1485Mbps. For other rates, the re-clocker automatically switches to bypass mode and the HDSDI-CHO-2x1 will work as a non-reclocking 2x1 change-over unit with cable equalizer. The HDSDI-CHO-2x1 also has a special DVB-ASI mode, enabling all possible rates including empty transport streams with only K28.5 padding packets. 2 outputs are non-inverting to support DVB-ASI compatibility.
The HDSDI-CHO-2x1 is designed for various line protection applications for studio, campus, broadcast and telecom.
New in firmware version 2.0.0 or newer: When latched to standby input, latch will not hold against missing signal on standby input if the signal on main input has been restored. Also, a
secondary timer has been added, which handles debouncing of the “signal on main input returns” condition. The primary timer handles debouncing of LOS on both main and standby
inputs.

3 Format Configuration
The HDSDI-CHO-2x1 can support a number of different formats. The correct configuration can either be set with a DIP switch or with the GYDA Control System. The layout of HDSDI­CHO-2x1 is shown in the drawing below with the DIP switch to the upper left position.
Figure 2: HDSDI-CHO-2x1 board layout
DIP switch configuration must be set according to the table below:
All DIP switches are off when pointing towards the release handle.
When the default setting is selected, all clock rates for HD, SD and DVB-ASI are automatically configured by the module itself.

4 Connections
The HDSDI-CHO-2x1 and HDSDI-CHO-2x1-PB has dedicated connector modules, SDI­CHO-2x1-C1 and FRS-HD-CHO-C1. These modules are mounted at the rear of the sub­rack. The modules are shown in the figure below.
Figure 6: SDI-CHO-2X1-C1 FRS-HD-CHO C1
The electrical input signals are connected to the IN1 and IN2 BNC’s. The electrical outputs are connected to the O1 to O4 BNC’s. Please note that only 2 outputs are non-inverted and
suitable for DVB-ASI. The Sync input connectors are not in use on this product.
The details of how the connector module is mounted, is found in the user manual for the sub-rack frame FR-2RU-10-2-xx.

5 Module status
The status of the module can be monitored in three ways.
1. GYDA System Controller (optional).
2. GPI at the rear of the sub-rack.
3. LED’s at the front of the sub-rack.
Of these three, the GPI and the LED’s are mounted on the module itself, whereas the GYDA
System Controller is a separate module giving detailed information on the card status. The
functions of the GPI and the LED’s are described in sections 5.1 and 5.2. The GYDA
controller is described in a separate user manual.
5.1 GPI alarm and control – Module status outputs and selection of inputs
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 the figure below.
As of hardware version 4 or newer of the product, the Status signal is inverted, sinking to ground when signal is good. Earlier versions have a non-inverted Status signal.
The two GPI inputs can be used to control switching of inputs. 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 the figure below.

(Text not printed on the front panel)
The HDSDI-CHO-2x1 has 4 LED’s each showing a status corresponding to the GPI pinning. The position of the different LED’s is shown in the figure above.
