Testing the Plotter Serial Port
The diagnostic module is required for this test.
1. Connect the diagnostic module directly to the plotter COM port.
2. From the Control Center main menu, select Test, Plotter Port Test.
3. Turn on the plotter while holding down the Roll key on the keypad.
Continue holding down the Roll key until the plotter beeps and the light
flashes three times. The plotter is now in Test Mode.
4. Press any Arrow key on the keypad to transmit and receive characters.
Verify that the plotter beeps.
5. Turn off the plotter at the end of the test. This will exit Test Mode. If this
test fails, the plotter port is faulty.
Testing the Computer Serial Port
The diagnostic module is required for this test.
1. Connect the diagnostic module directly to the COM port on the com-
puter. If the computer COM port has a nine pin connector, use a 9 pin to
25 pin adapter between the COM port and diagnostic module.
2. From the Control Center main menu, select Test, Computer Port Test.
3. Verify that the COM port selected is the correct one. If it is not, select the
proper COM Port.
4. Verify the CTS handshake line is on.
5. Press any key on the computer keyboard and verify that the character
transmitted equals the character received.
6. Select the Exit button at the end of the test. This will exit Test Mode. If
this test fails, the computer port is faulty.
COMMUNICATION TESTING
There are three communication diagnostic tests available in the Control Cen-
ter. These tests are designed to help determine if a communication problem
exists and to isolate where the problem is occurring.
A diagnostic module is required to run two of these tests. It will work on both
the computer and plotter serial (COM) ports. It is available from Ioline or an
authorized dealer.
Communication Test
This test will determine if communication is working between the computer
and the plotter on the serial (COM) port. Run this test from the Control Cen-
ter, Test menu. The diagnostic module is not required to run this test.
1. Turn the plotter off. Connect the plotter to the computer with a serial port
cable. See the section Connect the Plotter to the Computer in the Quick
Start guide for more details.
2. Start the Ioline Control Center. Select Test, Communication Test from
the menu bar at the top of the window.
3. Turn on the plotter while holding down the Set Gap key on the keypad.
Hold down the Set Gap key until the plotter beeps and the light flashes
three times. The plotter is now in Test Mode.
4. Press the Start/Stop key on the plotter and verify that the handshake line
(CTS) status displayed on the computer screen toggles On/Off. Leave
the handshake line On.
5. Press the Roll key to switch the plotter into Echo mode. The green light
will come on.
6. Press a key on the computer and verify that the character transmitted
equals the character received. If the characters match then the connection
between the plotter and computer is working properly.
7. Select Exit in the Control Center after the communication test is com-
plete.
8. Turn off the plotter at the end of the test. This will exit Test Mode.
9. The next two tests are not necessary if serial (COM) port testing is suc-
cessful.
