Error 47 . . . . . . More ports in box than listed in the non-volatile ram
Error 48 . . . . . . Wrong EPROM version

Any error not listed requires that the unit be serviced.
Long test with loopback
This test is entered by pressing the ADVANCE switch only while powering up the unit
with the on/off switch. Special loopback connector should be connected to each Porter
port.
Tests 1-5
These are the same as tests 1-5 of the ‘Long test without loopback’>
Test 6 – Module test with loopback
This test verifies that all port signals are functional. In order for this test to pass, special
loopback connectors must be installed on each port, see TABLE VII. If this test fails
(see TABLE VI) then a port communication chip has failed and the unit must be serviced.
The ADVANCE switch may be pressed to determine which port is the failing port. BUF,
DATA, and BUSY will all be flashing. The LEDs of all ports which pass will be flashing. A
failing port will have its corresponding LED steadily lit. Ports not installed will have their
corresponding LEDs off. This test will continuously execute until all ports pass or the test
is bypassed. In order to bypass this test completely, both the ADVANCE and SELECT
switches may be pressed.
