Sourcing Resistance (Rtds); Serial Communications - Martel MC1000 Manual

J. Sourcing Resistance Into a RTD
Transmitter
1. As described previously in section F the
MC1000 can source resistance in a RTD
Transmitter or measuring device. In many
cases the unit under test will require a 3 or 4
wire connection to achieve best accuracy.
Refer to Figure 10 for connection information.

4. Serial Communications

The MC1000 calibrator is equipped with a RS-
232 serial communications port, which is locat-
ed on the top of the case.
Note: The user will require a special RS-232
cable to connect the calibrator to a computer or
terminal.
Communication
Once the cable is attached, set the communica-
tions program settings as follows:
Baud Rate = 9600
Data Bits = 8
Stop Bits = 1
Parity
Flow Control = Xon/Xoff
