Module LEDs
The module has several LEDs included to indicate status. Function is
described below:
SDI Present LED
= Valid SDI Signal connected
= (out) Non valid SDI signal or signal missing
REF Status LED
REF Input is bi-level or tri-level analog sync (auto detect), and will cross lock and convert the
SDI output to the REF standard if there is a “mismatch” between the SDI in and REF.
= REF is present and matches the SDI input format
= REF is present but does not match the SDI input format. The SDI
output is being converted to match REF input standard
= (out) REF signal is not present / valid
Power / Status LED
= Power OK, and no internal programmed settings are present
= Power OK, and some internal programmed settings are active*
= Power OK, but the module switch settings have been overwritten
with the
yello
GUI
application.
(Manual operation of any local switch
will revert module back to the physical switch settings, and will change
LED status back to yellow or green).
= (out) Power not present
* Some additional internal settings have been made using
yello
GUI
and the
LED indicates this by turning yellow. The module can be reset to factory default
using the
yello
GUI
application, or by using the reset switch on the side of the
module, which can be accessed though a hole with a paper-clip (or similar)
USB Port
The USB port is used for firmware updates and for PC/MAC control using
the
yello
GUI
software. Download

GPI inputs
There are 4 GPI inputs provided
GPI 1
- Switches Fiber and Electrical inputs (dip switch 6 = ON)
GPI 2
- Freeze the SDI output
GPI 3
- (low) Enables “latch” mode
GPI 4
- (low) Disables “latch” mode
Delay Adjustment
A rotary control is provided to adjust the video output delay. A
maximum delay of 30 frames adjustable in frame / lines / pixels
increments is possible. Pressing (clicking) the rotary control cycles
between the 4 adjustment modes, which are indicated by the LEDs.
Connections
All connections are clearly indicated on the module. Electrical SDI and
REF IN connections are made using standard 75 Ohm BNC connectors.
The module supports 4 external GPI connections, these are contact
closure connections and are made using a standard RJ45 connector.
Connection details below.
Settings
A dip switch is provided for module
configuration.
Each switch function is described
below.

GPI
Connector RJ45 with4 x External GPI inputs:
GPI 1
is used for Electrical / Optical SDI changeover
GPI 2
is used for force a “freeze” of the signal
GPI 3
is used to enable the “latched” changeover mode
Power
+12VDC @ 5.5W nominal - ( supports 7 - 24VDC input range )
Note.
The depiction of the RJ45
connector and pin numbering is
made looking into the female
connector on the module.
1 = Freeze on TRS -
When set to ON the SDI output will “freeze” when a TRS error
is detected on the SDI input
2 = Freeze Mode
- Sets the freeze output to be the video image or test pattern
3= Output if no input
- Sets what the SDI output is when there is no input signal
4 = Test Pattern
- Turns the test pattern generator ON or OFF
5 = H-Flip
- Flips the SDI output horizontally
6 = GPI Switch Inputs
- When set to ON - GPI 1 will switch the SDI input between
electrical (GPI open) and Fiber (GPI closed) - this switch overrides the next
two switch settings
7 = Auto Input Select
- If the main input is lost then the module automatically
switches to the other SDI input. The “main” input is determined by the
setting of the next dip switch
8 = Fiber Input
- Switch SDI input between Electrical (OFF) and fiber (ON)
When an LED is illuminated turning
the rotary control will adjust the
delay in the selected increments
(frames / lines / pixels).
The 4th mode is an “overview” mode and all 3 LEDs will be
green
if
there is no delay adjustment set (0) and
yellow
if the setting is not zero.
Turning the rotary control will have no effect in “overview” mode.
Power Lead Strain Relief
The module has a small hole in the case located above the power
connection. To prevent the power lead being accidentally pulled out,
use the supplied tie-wrap and secure the lead as shown below.
GPI 4
is used to disable the “latched” changeover mode
