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

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.
