12 Care and Usage Information
12.1
Precautions for Handling and Storage
1. For proper operation, environmental and power supply limitation requirements must be adhered to.
2. Do not expose the PCM-2074 to chemicals or to liquids, such as water or oil, or to moisture or
vapor during handling or storage. Such exposure may result in electrical shock, short circuits,
damage to the PCM-2074, or fire.
3. Use and store the PCM-2074 on a stable, level surface, and avoid mechanical vibration or shock.
4. Do not subject the PCM-2074 to direct sunlight or excessive heat. Exposing the board to excessive
heat during use may damage it. Exposing the board to direct sunlight may cause damage or
warpage.
5. Do not use or store boards in dusty places.
6. Avoid using the PCM-2074 near TVs, radio receivers, cordless phones or similar devises. The
PCM-2074 may cause Electro-Magnetic Interference with these devices.
7. Do not use or store the PCM-2074 near equipment that generates strong electro-magnetic fields.
Exposure to excessive Electro-magnetic fields may damage the board.
8. Do not put heavy loads on top of the PCM-2074 as this may damage it.
9. Avoid exposing the PCM-2074 to exogenous material such as metal particles. These may cause
short circuits and fire.
12.2
PC Installation Procedure
1. Confirm that all jumpers and dip switches on both the Main Board and the RS485 Board are set
correctly.
2. Attach the RS485 Board to the Main Board using the ribbon cable, then insert the Main Board into
a PCMCIA slot, avoiding excessive force and aligning the card and slot correctly.
3. Avoid inserting or removing the RS485 Board during the power-on state.
4. Avoid excess stress on the ribbon cable connecting the Main Board to the RS485 Board.
5. Be sure not to exceed current consumption limits when providing power via CN1 or CN2.
6. Confirm correct operation of the evaluation board.
12.3
De-Installation Procedure
1. Power off the system before removing boards or connectors to prevent damage.
2. Avoid excessive force when removing cables, boards, sockets or devices to avoid damaging them.
12.4
Miscellaneous Warnings
Attaching the PCM-2074 to a non-SMSC authorized fixture or PC may cause the following failures.
The PC may not function correctly.
The board does not work or exhibits intermittent failures.
The board causes damage to either the PC or other peripherals.
If there is a possibility that adjacent boards may contact each other, insert an insulator between them
to avoid electric contact which may cause a defect in the board, system or peripherals, electric shock,
or fire.
