The PS2000A supports the broadcast access of the network server that uses the super
Device_ID code (0FFh, 0FFh, 0FFh, 0FFh, 0FFh, 0FFh, 0FFh, 0FFh). But the PS2000A
will not respond to the command sent by the network server with the super Device_ID.
The object name supported by the PS2000A is an ASCII character string ended with
NULL. The string size of the object name is less than 13.
The following characters are allowed in an object name string:
1. English letters: a~z, A~Z;
2. Number: 0123456789;
3. Other character: Dollar ($), underscore (_), #.
The first character of an object name string must be an English letter or ‘$’.
The object name supported by the PS2000A is not case sensitive.
The check value of CRC check used in the PS2000A is calculated by the MCUap
TM

protocol application layer data packet (from the first byte of Server_ID to Data (n-1)).
The sending order of the CRC word is MSB first and LSB last.
The CRC generating multinomial is X

+ X

+ X

+ 1. The C language algorithm is as
shown below:
unsigned short
ComputeCrc(
unsigned short
crc,
char*
bufptr,
short
len)
{
int
i;
crc = 0;
while
(len--) { /* calculate CRC from end to start */
crc ^= (unsigned short) (*bufptr++)<<8;
for
( i=0 ; i<8 ; ++i ) {
if
(crc & 0x8000)
crc = (crc << 1) ^ 0x1021;
else
crc <<= 1;
}
}
return
(crc);
}
