34 Front-Panel Operation
1. Select a slot. Press the two arrow keys to select a desired slot directly,
or turn the knob to select the desired slot number.
2. Select a channel. Turn the knob to select a channel (3 digital
number). As shown below, the top display indicates the current
channel 101 is a MUX channel and in OPEN state, and the lower
indicates that the current bit 401 is a digital input port.
Note Open, Close, Read and Write keys are invalid if a slot, instead of a
channel, is selected.
To demonstrate the following operations more easily and clearly, we assume
five modules have been installed in an Agilent 3499A mainframe. The
configuration is:
Local/Remote Control
When power-up, the instrument is in local mode. All keys on the front panel
are fully functional. When receiving any command from the remote
interface, the instrument automatically switches to remote mode (ADRS and
RMT annunciators light up), all front-panel keys are locked, except the keys
Local, Mon, View, Enter, the two arrow keys and the knob.
Local and Shift use the same key. While in local mode, it is used as Shift
key. While in remote mode (the RMT annunciator turns on), it is used as
Local key.
To Monitor a Channel or a Slot
In a switch/control system, it is necessary to acquire, confirm and
continuously monitor the current status of a particular switching channel, a
