Adding Two Local Bits
Target LED Settings
The SEL-751A offers the following two types of LEDs. See
and
for the programmable LED locations:
➤
Six Target LEDs
➤
Eight Pushbutton LEDs
Your can program all 14 LEDs using SEL
OGIC
control equations, the only
difference being that the Target LEDs also include a latch function.
Target LEDs
Settings T
n
_LEDL (
n
= 01 through 06) and T
n
_LED (
n
= 01 through 06)
control the six front-panel LEDs. With T
n
_LEDL set to Y, the LEDs latch
after assertion. To reset these latched LEDs, the corresponding LED equation
must be deasserted (logical 0) and one of the following takes place:
➤
Pressing
{TARGET RESET}
on the front panel.
➤
Issuing the serial port command
TAR R
.
➤
The assertion of the SEL
OGIC
equation RSTTRGT.
With T
n
LEDL settings set to N, the LEDs do not latch and directly follow the
state of the associated SEL
OGIC
control equation setting.
