Circuit Test
To test the
1.Set the DCE / DTE switch to the opposite of the terminal.
2.Set all DIP Switch segments to ON.
3.Connect one wire from Tx+ (1) to Rx+ (4); connect a second wire from Tx- (2) to Rx- (3).
4.Set the terminal to Full Duplex.
5.Set the baud rate of the communicaton application to 1200 bps.
6.Enter data.
If the circuit is operational, data appears on the screen
