to logic low
2
, and vice versa; When the CTS is logic high
2
, it prevents further
transmission of data, the data will be stored in the transmit buffer until CTS is
logic low.
DTR/DSR

:
When the device (balance or printer) can receive data, set the
DTR to logic low
2
, and vice versa; When the voltage of DSR(printer side)
exceeds 2.5V, it prevents further transmission of data, the data will be stored in
the transmit buffer until the voltage less than 1V.
Note:
1. XON: 0x11(Hex), XOFF: 0x13(Hex)
2. The transmit buffer size of the printer is 32 bytes.
3. Logic low: 5~15V (RS-232C), 0~1V (TTL);
logic high: -5~-15V (RS-232C), 3~5V (TTL);
4. DTR/DSR can be used SHIMADZU TX series balance which has the
D-Sub9 port.
Connection:
Handshake = None, XON/XOFF:
Handshake = DTR/CTS
