Communication Time Delay
When transmitting 1 packet(11 bytes), keep 2
milli-seconds waiting time between bytes.
Advice for communication
•
If the command packet is transmitted
only 4 bytes, then the camera will wait
for remain 7 bytes continuously.
At that moment, if a new packet is
transmitted to the camera, the previous 4
bytes will be ignored.
•
If the camera doesn’t send any response
packet, there should be some troubles in
communication line or any other
communication condition.
•
If the camera response mode is Skip
Command response packet mode, then
the camera will not send Command
response packet. Even if the response
mode is Skip Command response packet
mode , the Data response packet will be
transmitted to PC.
After transmitting the first packet, wait for
25 ms to transmit next command packet.
•
Byte delay time > 2ms
•
Packet delay time > 25ms
*) Byte delay and Packet delay is a time delay
for stable communication.
