Serial Port Test

The Serial Port Test is a loopback test that checks

whether data is being correctly transmitted and

received on any port. The test also checks, using

DTR/CTS/RI or RTS/DCD, whether the box can

loop back control leads correctly. To use this test,

you will need to jumper Pins 2 and 3. To test

DTR/CTS/RI and RTS/DCD, you’ll need to

jumper Pins 20, 5, and 22 together, and jumper Pins

4 and 8 together.

Interrupt Test

The Interrupt Test checks the interrupt circuitry of

the unit. During this test, the letter “A” will appear

on screen. A message will indicate whether the test

was successful.

All Tests

If you request All Tests, the COS-II will run all the

listed tests in sequence.
