The data format is
8 data bits include parity
1 stop bit
The instruction to connect the balance to external device is as follows,
1
PIN
DESCRIPTION
2:TXD---- scale transmits data
3:RXD---- scale receives data
5:GRD---- signal ground
Notice:
o "handshake" signals, such as "clear to send" (CTS) are not used. The peripheral
must have a minimum buffer (15 characters).
o It is suggested that the maximum recommended cable length is 15 meters; the
load impedance of the device connected should be between 3000 and 7000 ohms
with no more than 2500 pf shunt capacitance.
