Patch Card
The patch card features two indicators: XMIT and ACTIVE. The XMIT indicator shows
that a transmission is active on patched channels. The ACTIVE indicator shows that a
patch between channels is selected.
Indicator Description
PASS (green) Normally on. If this is off, the card has failed (or is failing) a diagnostic. Shorting
the two pins of the “FAIL-RESET” jumper or pushing the “FAIL-RESET” push-
button will turn this indicator back on. Depending on the detailed diagnostic on the
system log, this card may or may not be in error.
FAIL
(red)
Normally off. If this indicator is on or blinking, the card is continually failing a
diagnostic. Press the “CARD-RESET” button and if the indicator continues to
blink, the card must be repaired or replaced. The diagnostic log may not indicate
the nature of this problem.
POLL
(green)
Normally dimly winking (mostly on). If this indicator is pulsing (mostly off), it is
not communicating with the rest of the system. Press the “CARD-RESET” button.
If the indicator continues to pulse, rather than wink, the card will need service. The
diagnostic log may not indicate the reason for this problem. This indicator is not
applicable to the STC card.
ERROR
(red)
Normally off. If this indicator is on, the card has detected an error that may not
relate to the card itself. Check the system diagnostic log for details on the error.
Pressing “CARD-RESET” should turn this indicator off.
Switch Description
CARD RST Resets the STC microprocessor.
FAIL RST Re-lights the PASS LED if it turned off because of watchdog failing, static
discharge, or hardware failure.
Indicator Description
XMIT (Transmit) This LED is on any time this CIC is commanding a channel to
transmit.
CONS. LIVE (Console Live) This LED shows proper connection to the console. If this LED
is not lit, the console position is inoperable.
CONS. DATA (Console Data) This LED will flash any time data is received from the console.
CIC DATA (Console Interface Data) This LED flashes when the CIC sends data to the
console.
