1. Introduction
1.1. Introduction to CSH2
CSH2 is specialized in converting SDI input signal to HDMI or DVI output signal, and it
can transmit digital audio signal via the optical fiber.
Integrated with 3G/HD/SD receiver and HDMI encoder, CSH2 can turn the 3G/HD/SD
signal to HDMI/DVI signal easily. At the same time, CSH2 can separate the audio signal
from the 3G/HD/SD signal, and send it to the HDMI output port, that makes the sound
perfectly synchronize with the images.
CSH2 is a green low energy consumption product that deserves owning it. It has a good
application in different places, including classroom, small meeting room, lecture hall, bar,
pub etc.
1.2. Features
 HDTV compatible with High Definition Transmission resolution up to 1920*1080
(max).
 Bandwidth: 2.97Gbps
 With one analog audio output, and one SPDIF (digital audio) output which is
transmitted via the optical fiber.
 Support with different SDI modes: including 3G, HD, and SD.
 Output signal can be set to HDMI/DVI signal.
 Supports various output resolution.
 Looping output function is supported.
 Supports fault diagnosis and local monitoring, with LEDs indicate the real-time
running state.
 Full aluminum metal jacket, fits for wall mounting or desktop mounting.

3.2. Connection Procedure
Please reference to the system diagram before your system installation. A detailed
installation procedure is showed as follows.
Step1. Connect the input SDI signal (such as SDI camera) to the SDI IN port on the rear
panel of CSH2 by using a SDI cable.
If you need two outputs, please connect the SDI LOOP port on the rear panel of
this CSH2 to the SDI IN port on another CSH2 by using another SDI cable.
Step2. If long distance audio transmission is requested, please connect the DIGITAL
AUDIO output port to the optic-fiber accepter (SPDIF decoding included) by
using an optical fiber.
Step3. Use an audio cable to connect the L&R of the AUDIO OUT port with audio
device to output analog audio.
Step4. Use a HDMI cable to connect HDMI OUT port of CSH2 converter with a display
device to output the HDMI signal.

5. Special Functions Introduction
5.1. Looping Output Function Introduction
Looping output function is supported in CSH2, showed in Figure 3. In this mode, the
signal pass through the SDI IN port to the SDI LOOP port of the first CSH2, and the SDI
LOOP output port can be connected to the SDI IN port of the next CSH2, and so on.
Finally it makes a looping output. In this way, one input signal can be allocated to
several outputs. This is a good solution for a single input with lots of display devices.
Note: With 3G-SDI signal, only two pieces of CSH2 can be used in a looping
connection.

5.2. SDI Signal Modes Introduction
CSH2 supports three SDI signal modes, includes 3G, HD and SD. The corresponding
resolution and frequency of these three modes are showed as follows.
 3G mode: 1080P @60Hz/59.94Hz, 1080P @50Hz/49.95Hz
 The resolution of HD mode is showed in the table below.

7. Troubleshooting & Maintenance
1) When images of terminal unit output with ghost, such as the projector output with
ghost. Generally this is not a unit faulty, this may be caused by an incorrect setting
on the projector or a bad quality of cable. Please check the projector’s setting or try
another high quality connection cable.
2) When there is a color losing or no video signal output, please check the input and
output end connections of the cables.
3) When there is no output images:
 Check if there is any signal at the input.
 Check if there is any signal at the output.
We can check these by using an oscilloscope or a multimeter. If there is no signal
input/output, maybe the input/output cables broken or the connectors loosen,
please change for another cable.
 If not the problem mentioned above, probably there is something broken inside
the unit, please send it to the dealer for repairing.
4) Before using CSH2, please make sure that all cables (such as audio cables, fiber
PTN Electronics Limited

SDI to HDMI Converter
etc.) are connected well before accessing the power of the product.
5) If the POWER indicator doesn’t work or no respond to any operation, please make
sure the power cord connection is good.
6) If the output image is interfered, please make sure the system is grounded well.
7) If the static becomes stronger when connecting the audio or video connectors, it
probably due to bad grounding, please check the grounding and make sure it
connected well, otherwise it would damage the converter.
8. Safety Operation Guide
In order to guarantee the reliable operation of the equipments and safety of the staff,
please abide by the following proceeding in installation, using and maintenance:
1) The system must be earthed properly. Please do not use two blades plugs and
ensure the alternating power supply ranged from 100v to 240v and from 50Hz to
60Hz.
2) Do not put the device in a place of too hot or too cold.
3) As the power generating heat when running, the working environment should be
maintained fine ventilation, in case of damage caused by overheat.
4) Cut off the general power switch in humid weather or left unused for long time.
5) Before following operation, ensure that the alternating current wire is pull out of the
power supply:
Take off or reship any components of the equipment.
Take off or rejoin any pin or other link of the equipment.
6) As to non-professional or without permission, please DO NOT try to open the
casing of the equipment, DO NOT repair it on your own, in case of accident or
increasing the damage of the equipment.
7) DO NOT splash any chemistry substance or liquid in the equipment or around.
