4. Mechani cal Requirements and Dimensions
The figure below shows the dimensions and the connector orientation for the Video Server / IP camera
module. These dimensions are necessary to accommodate the module into the final product system. It also
shows the mounting mechanism to system OEM for securing the video server module to the final system. It is
strongly recommended that the system OEM utilize the mounting holes to ensure the long term mechanical
reliability of the system.

6. Important design notes
For users designing their own I/O connector board for the intended IP camera product, please refer to the
following sections for suggestions, and create your own PCB board. Please note that the company supplying
the module has no liabilities or responsibilities to the design and manufacturing of the I/O connector board.
6.1 I/O connector board circuitry
The I/O connector board is the board with necessary I/O connectors for user to attach cables intended
for Power, Ethernet, CVBS output etc. Please note that the simplest design is to place all I/O connectors
such as power, audio in/out, CVBS output, Ethernet RJ45 port, status LED etc onto one single board,
but this is subject to your camera design.
When laying out the back panel that contains both video and audio signals, make sure that adequate
grounding between these two signals is done properly.
6.2 Thermal consideration
The main IC (ASoC 3100) on TMU-9501 will heat up under 50Deg.C chamber environment with full
enclosed casing. The surface temperature of our module should not exceed +115 Deg.C, otherwise
failure of components may occur.
The temperature dissipation of the module may cause the CCD’s sensor chip to deteriorate in video
quality if inappropriately placed.
Basically, the ASoC3100 should be placed in a direction that is facing AWAY from the CCD module.
Camera type
TMU-9501
Placement suggestion
Box camera
OK
1. ASoC3100 face away from CCD module
2. ASoC3100 face towards bottom casing, with thermal pad
in-between to dissipate heat
3. TMU-9501 module is placed at a distance away from CCD
module, ie. In middle of the camera or towards the back panel of the
camera
Fixed dome
Depends on
dome design
1. If the dome housing has an upper compartment for mounting, then
TMU-9501 can be placed in that compartment. This is ideal, as it is
far away from the CCD module
2. If the dome has no upper compartment and is limited for space,
then TMU-9501 can be placed with the board lens fixture (Limited
distance in between CCD module and TMU-9501)
3. If placed with board lens fixture, then use a CERAMIC thermal
pad to block the heat from affecting the CCD’s sensor chip.
6.3 Cable design
(i) The differential impedance of the cable for network part (J13 of TMU-9501 module) needs to be at
100 Ohms
(ii) The Tx+ / Tx- cabling needs to be twisted together as a pair.
The RX+ / RX- cabling needs to be twisted together as a pair.
Without conditions (i) and (ii) met, IEEE802.3 network test is near impossible to pass.
6.4 Hardware reset
Hardware reset is a necessary function for unforeseen failure, such as power surge. The picture below gives
an example of the cable design. Corresponds to J4 connector (Boot up LED & Reset to Default)
Standard procedure to apply hardware reset:
Step 1: Power off IP module
Step 2: Press and continue to hold the reset button. Reconnect the power supply while continuing to
hold the reset button.
Step 3: Keep the reset button pressed for about 15 seconds, and then release the reset button. The unit
will start up with factory default settings.
