Front Panel Controls
The Model 725 front panel controls begin with the Power button and Power LED in the upper
left corner. When you first press the Power button, the LED will flash green and red while the
system runs its initial diagnostics. It will then glow steadily: if it glows a steady green, the front
panel is unlocked and accepting button pushes; if it glows red, the front panel is locked (see
timerPRO Software Interface: General Settings below). Even the power switch will be
deactivated, safeguarding against mis-setting or tampering.
The channel LEDs offer useful information about the state of each channel. A green light
typically indicates that the channel is ready to receive a trigger. A red light typically indicates that
the channel is in the process of triggering. When a channel indicator is off, the channel is disabled
(see Running Experiments: Enable/Disable Channels). More will be discussed in the Timing
modes section.
The All Channel LED shows the status for all channels. A green LED indicates that the Model
725 will respond to external inputs and that the external outputs are active. A red LED indicates
that the Model 725 will not respond to external inputs and that outputs are in a fixed and frozen
logical state.
The Channel and Function Buttons work as pairs—you will select one of each to perform any
function. In the base state, all buttons glow dimly, indicating that they’re ready for your
instruction. Once you press a channel or function button, only the available options will be
illuminated.
