SynchroNet ES/2 Service Manual ES/2 TEST SOFTWARE TEST 02 : keys This test asks the user to press each key in turn. When the requested key is pressed the ES/2 will ask for the next key in the sequence to be pressed. When all keys have been pressed in sequence and read by the ES/2 the test will have passed and the test select menu is automatically entered. The following screen is displayed at the start of the test : Press the key marked: Test 02 Menu . When the ES/2 detects a key press then it displays the name of that key on the right hand side of the ‘.’. The ES/2 will remain waiting for the requested key to be read. TEST 03 : LEDs This routine displays the following screen: Check the lower row of LEDs are cycling Test 03 Press if okay > The ES/2 will light each of its KERNEL LEDs in turn starting on the left had side of the program module with the Bus ON LED and ending on the switch board with the GOOD CODE LED. The LEDs will cycle in this way until key 4 is pressed. TEST 04 : cmd o/ps. In order to see the command relays active, the parallel machine connector dongle, detailed in appendix A, is required for this test. This routine displays the following screen: Check the command outputs are cycling Test 04 Press if okay > This test energises each command relay briefly in turn. The associated LED on the command outputs of the parallel machine connector dongle should light in turn. The routine will continue running until key 4 is pressed. TEST 05 : Tally’s The parallel machine connector dongle, detailed in appendix A, is required for this test. It provides a path from the command relays outputs to the tally inputs. The test first sets the tally polarity by setting the TPOL line high. It then briefly energises each the command relays 0 through 3 and reads the tally input. If the response is not what was expected then the following is displayed and the test fails. Tally Input Failed Rerun > Press to continue > If the first part of the test passes then the TPOL line is inverted and the ES/2 checks that the data read from the tally latch has inverted. If this is not the case the the following is displayed and the test fails. Tally Polarity Failed Rerun > Press to continue > Issue 1 2:3
ES/2 TEST SOFTWARE SynchroNet ES/2 Service Manual If either of these tests fails then pressing the Rerun key (key 3) will restart the test. If the tests pass then the following screen is displayed: Tally inputs Check Test 05 Okay.. Press to continue > After the test has been completed, whether it has passed or failed, the ES/2 will continue energising the command relays and wait for the continue key (key 4) to be pressed. This is to allow some form of debugging to take place. TEST 06 : CTCs This test checks the three KERNEL counter timer chips, CTC1 - U54, CTC2 - U55 and CTC3 - U56. Each timer is tested in turn and each test consists of two tests. 1) A check to see if the CTC chip is present. All timers are stopped and preset. The ES/2 reads the CTC and checks that the preset data is read back. If the data is different to that expected then the following message is displayed. Timer X faulty or re-run > not fitted Press to continue > 2) The second check starts timer 1 going, reads in the timer value after a delay and checks that the counter has actually started. It it has not then the following screen is displayed : Timer X re-run > counting error Press to continue > If either test fails then pressing the re-run key (key 3) will start the test from the point which failed and continue through the tests. If the continue key (key 4) is pressed the the CTC test is exited. If all timers pass the tests then the following screen is displayed and the ES/2 will wait for the continue key (key 4) to be pressed. TEST 07 : film lo Timers check Test 06 Okay.. Press to continue > In order to see the film output, the parallel test connector dongle is required for this test. The two film LEDs should be observed. The routine displays the following screen : Film output LEDs should be showing Test 07 bi-phase Press if okay > The film outputs are set to bi-phase, started and enabled. The servo generator is set to approximately 4Hz. This should result in a bi-phase output of 1Hz. The ES/2 will continue to output the bi-phase until the continue key (key 4) is pressed. 2:4 Issue 1
