|
RS232, RS422, RS485 Communications Port
|
Com port outputs Torque and Temperature with units of measure. Inputs torque range if other than sensor full scale, selects units of measure,
selects BAUD Rate, and permits remote computer control of the test.
|

RS232 = 50 feet, RS422/485 = 4,000 feet; 120 Ohm termination may be accessed via software.
|
Interface Software
|
Provided to interface with Windows-based PC. Includes interconnect cable for a PC.
|
I/O Lines
|
5 input and 2 output, all are user assignable. Default for 5 inputs are +CAL, -CAL, TARE, CLEAR TARE, and RESET MAX/MIN.
|
Status LED’s (on Stator Keypad)
|
Three Color Coded LED’s: Power (Yellow = Power-up, Green = OK, Red = Fault); Data (Green = OK, Red = Data Error);
Rotor Temperature (Green = In Operating Range, Red = Out of Operating Range).
|
Keypad Control Switches
|
+ CAL invokes CW Rotor Shunt Cal, -CAL invokes CCW Rotor Shunt Cal, Both held simultaneously for 5 seconds invokes TARE.
|
