Packet mode of serial
input
If packet mode is disabled, the data received
from the serial port will be transmitted
immediately with minimal delay. If packet
mode is enable, the data will be saved in the
buffer memory first, and transmitted when the
entire packet is received or when the buffer
memory is full
Packet mode
inter-packet timeout
In packet mode, the time constant used to
determine
if
the
packet
is
finished,
acceptable range is 10 to 1000 ms.
Device ID
User assigned device ID number, acceptable
range is 0 to 65535.
Report device ID when
connected
If this function is enabled, the device will
report the device ID after the socket is
connected. The format is
：
Serial I/O socket nnnnnA[LF][CR]
Digital I/O socket nnnnnB[LF][CR]
There are eight bytes
：
nnnnn is the 5-digit
device ID, [LF] is decimal 10, and [CR] is
decimal 13
