10.3 Usage
precautions
10.3.1 Connecting and disconnecting equipment
Before attaching or removing the target system and cables, and setting the DIP switch and
jumper, be sure to turn off the power to the host computer, S5U1C33001H, and target
system. Failure to take this precaution may result in equipment malfunction.
10.3.2 Powering
on/off
After turning off the power to the S5U1C33001H, wait at least 10 seconds before turning
the power on again. If the power is turned on immediately after it is turned off, the
S5U1C33001H may not be initialized correctly in a power-on reset, and may cause a
malfunction.
10.3.3 Connecting the target system
The signals connected to the S5U1C33001H are very high-speed signals, so the target
connector must be mounted within 5 cm from the S1C33xxx. If there is more distance
between the connector and the S1C33xxx chip, the S5U1C33001H may not work properly.
Furthermore, be sure to use one of the supplied 10-pin and 4-pin cables, or 30-pin cables
for connecting the target system to the S5U1C33001H. Using two cables (30-pin and
10-pin or 4-pin cables) simultaneously or using another cable may cause a malfunction.
*1: The product package does not include a 30-pin cable or the corresponding connector.
Please contact us if you need this cable or the corresponding connector.
10.3.4 Operation of the S5U1C33001H system
The S5U1C33001H can work by connecting a target system in which the actual S1C33xxx
chip is mounted.
Since the S5U1C33001H package does not include any board equivalent to a target system,
please prepare separately.
