Scale Basic 4.2E Tutorial
EZ Link Test
Use this procedure to test the connection between the indicator and the PC.
On the PC:
If you are using Windows 95, access the Hyperterm program from the Start menu / Programs /
Accessories / Hyper Terminal. In Windows 3.1 use the Terminal program. Configure the
Hyperterm program using the parameters entered above for the indicator.
On the indicator:
Hold the CLEAR key down and press the ENTER key to enter the configure mode. Enter CFG
69. The indicator prompts “diA xx” where xx is the currently selected test number.
Test 4
Enter test number 4 and then press the ENTER key. This test displays serial data as it is
received by the indictor’s serial communications port 2. The numeric display has limited alpha
display capability, however numeric and some upper case alpha characters are legible. Type
numeric data on the PC’s keyboard.
If there is no change on the indicator’s display:
1. Is the Hyperterm program configured for the correct PC Com Port (the one your
communications cable is plugged into)? Check the Com port number used in Hyperterm and
confirm that it is the same port that the cable is plugged into at the back of your computer.
2. Is the indicator receiving the data? Use a volt meter between pins 3 and 5 on the indicators
port 2 terminal . The volt meter should indicate a negative voltage (approximately -5V to -
12V). Type data on the PC keyboard. The volt meter should deviate when data is typed. If
not, then the cable is wired incorrectly.
3. Is the RS232/RS485 jumper in the correct position for port 2?
If all data being received is unintelligible:
Are the configuration parameters for PC Terminal program the same as the parameters for the
indicator (baud rate, data bits, and parity)?
