and when R49 is connected, the device is working in Slave
mode.
When in host mode, there is a pin setting to set the bit rate to
9600bps or 19200bps. We used ID1 for this setting. When
ID1 is short, the bit rate is set to 19200bps, and when ID1 is
open, the bit rate is set to 9600bps.
When in host mode, there is 3 pin setting (ID4, 5, 6) to set
the quantity of slave device. When ID4 is short, the host
support to 8 pcs slave device; and when ID5 is short, the
host device support to 16 pcs slave device; when ID4 & 5 are
short, the host device support to 24 pcs slave device; and
when ID6 is short, the host device support to 32 pcs salve
device.
When device is working in Slave mode, the 8x3 jumper connector
is used for ID setting. As the picture below showed:
In the new device, we have change the ID setting mode. The ID
setting was divided to single digit and tens digit.
1-5 and 12-16, total 10 pins have changed to the single digit (1-1,
2-2, 3-3, 4-4, 5-5, 12-6, 13-7, 14-8,15-9, 16-10, none-0); and 6-8,
total 3pins have changed to tens digit (6-10, 7-20, 8-30).
When set the slave ID, we need to short the single digit and/or tens
digit.
Such as if we set the slave ID as ID9, then we need short the
current pin 15. If we set the salve ID as ID10, then we need short
the pin 16 (or short pin 6). If we set the salve ID as ID20,then we
need short the pin 7 (or short pin 6 and pin 16); If we set the slave
