PDP-5010FD

Specifications for port monitoring

Port Name

SD/PD Indication

Active

RST2

ASIC power
(M-DCDC)

Shutdown occurs when the
signal is "L."
for 5 sec after PSW1 is ON.
or
for 2 sec while the unit is
ON.

RST3

AC power

AC_OFF when the signal is
"H."

Monitoring conditions

• Panel ON (RST4 = H and
PSW1 = L)
• While awaiting restoration
of RST2 (RST2 = L)

Operation

The SD timer starts when "RST2 = L" is detected under
monitoring conditions. If "RST3 = H," "M_SW_DET_B = H," or
"RST4 = L" is detected, or if a power-down or shutdown in the
module microcomputer system is not generated, the unit waits
for 30 mS. Then, if the SD timer continues to count for 2 sec
or more, a shutdown is determined, and a shutdown process
starts. A specific LED flash pattern (blue LED, 13 times)
starts. The next PON operation is valid, and the flag is cleared
upon the next power-on.
If RST2 is H, a restoration process starts according to the
latest power-on/-off status.

• Active STB (including SD/PD
statuses)
• Functional STB
• Panel ON
• (Areas other than North America)
While the main power switch is
set to OFF (M_SW_DET_B = H)
• (North America) While the main
power switch is set to OFF
(M_SW_DET_B = H)
• While awaiting restoration of AC
power (RST3 = H)
• While awaiting restoration of
RST2 (RST2 = L)
• While awaiting restoration of
RST4 (RST4 = L)

If "RST3 = H" (AC_OFF) is detected under the
monitoring conditions, a power-off process starts.
Monitoring of the RST3 port is continued, while
monitoring of other ports is interrupted.
Communication is controlled only by the IF
microcomputer. The port outputs are set as specified.
If the signal at the RST3 port continues to be H after
30 mS of waiting, monitoring is continued.
If RST3 is L, a restoration process starts according to
the latest power-on/-off status.

RST4

MAIN power
(RELAY)

Shutdown occurs if the
signal is "L."
for 5 sec after RELAY is
ON.
or
for 2 sec while the unit is
ON or in Functional STB.

• Functional STB
• Panel ON
• (Areas other than North America)
While the main power switch is
set to OFF (M_SW_DET_B = H)
• While awaiting restoration of
RST2 (RST2 = L)
• While awaiting restoration of
RST4 (RST4 = L)

The SD timer starts when "RST4 = L" (power-off of
devices in the functional STB system) is detected under
monitoring conditions.
The RST4 initialization process starts, and input
monitoring, communication setting, and output-terminal
setting are performed.
The RST4-SD timer starts. If either "RST3 = H" or
"M_SW_DET_B = H" is detected, or if a power-down or
shutdown in the module microcomputer system is not
generated, the unit waits for 30 mS. Then, if the SD
timer continues to count for 2 sec or more, a shutdown
is determined, and a shutdown process starts.
A specific LED flash pattern (blue LED, 13 times) starts.
The next PON operation is valid, and the flag is cleared
upon the next power-on.
If RST4 is H, a restoration process starts according to
the latest power-on/-off status.
