Internal Diagnostics
When 3 is selected from the Service Diagnostics Menu, you are prompted to enter a number from 1 through
7 to select the desired test.
1 – Supervisory –
This test allows the optional supervisory board to be tested. The Supervisory test
exercises supervisory control on each channel.
2 – Phone –
In this test the optional phone-patch board is tested. The test allows audio to be routed to and
from the phone patch board.
3 – DC –
This test allows the optional dc boards and channels to be tested. The channel positions for dc
boards and the current output on each board are tested.
4 - RS232 –
This test allows the RS232 communication port to be tested. The transmit and receive paths
of the RS232 are checked as well as the transmit and data paths of the RS232 cable. This is done by
shorting transmit and data at pins 10 and 11. For this test, the TX and RX pins of the RS232 port must be
connected.
5 - I/O Pins –
This test allows the general purpose and encode in/out pins of the RS232 port to be tested.
6 - E&M –
This test allows the optional E&M board to be tested. The E&M board exercises the M lead
outputs and reads the E lead inputs for each channel present.
7 – Memory –
This test allows CARD Suite parameters in hexadecimal form to be examined on the
console screen. The cursor can be moved left by pressing the
4
button or right by pressing the
6
button.
The value of the memory location where the cursor is positioned can be increased by pressing the
8
button
or decreased by pressing the
2
button. Caution should be observed in modifying the memory of the console
as improper setting can cause the console to be unusable and require reloading of the CARD Suite
parameters.
Alert Level
When
4
is selected from the Service Diagnostic Menu, and the correct password had been entered, you are
prompted to adjust the Alert Tone Level. The alert tone level is adjusted by using the scroll keys to
increase or decrease the tone level. The available adjustment levels are –15 dB to 0 dB in –3 dB
increments.
Page Level
When
5
is selected from the Service Diagnostic Menu, and the correct password had been entered, you are
prompted to adjust the Page Tone Level. The page tone level is adjusted by using the scroll keys to
increase or decrease the tone level. The available adjustment levels are –15 dB to 0 dB in –3 dB
increments.
Security
When
6
is selected from the Service Diagnostic Menu, you are prompted to select the desired security level
using the numeric keypad. No security is useful during initial set-up and installation so the password is not
required while adjusting line levels and other levels. The highest security level provides complete
restriction to the console diagnostics and user adjustments.
