For a four-pole operation, the paired channel is not displayed on the front panel.
Viewing status from the remote command interface
To view a list of closed channels, use the channel.getclose() command. For example:
print(channel.getclose("allslots"))
To view the close and open status of channels, use the channel.getstate() command.
Viewing status from the instrument web page
To view status from the instrument web page, from the list on the left, select the slot that contains the
channel. The status is displayed on the web page for the slot.
Channel attributes
You can use the front panel and command options to set attributes for specific channels. Some of the
attributes you can set are adding a delay, forbidding closure of a channel, and setting channel labels,
which are described in the following sections.
Setting and querying channel attributes
You can view and edit channel attributes on the front panel using the channel attributes menu. To
access the channel attributes menu, press the CONFIG key and then press the CHAN key. Use the
navigation wheel and CURSOR keys to change attribute values. Use the ENTER and EXIT keys to
apply or cancel settings.
With the exception of the DMM configuration attribute, you can view and edit channel attributes using
the remote command interface using the channel commands. For example, to set the label attribute
of a channel, use the channel.setlabel command; to retrieve the label attribute of a channel, use
the channel.getlabel query.
To set the DMM configuration attribute for a channel or group of channels, use the dmm.setconfig
command and specify the channels in the channelList parameter. To retrieve the DMM
configuration attribute for a channel or group of channels, use the dmm.getconfig query.
For specific instructions on retrieving the relay closure count attribute, refer to Determining the
number of relay closures (on page 5-16).
Set additional delay
You can set an additional delay to incur after the relay settles when closing.
To set additional delay time from the front panel:
1. Display a channel (you might need to press DISPLAY).
2. Select the channel for which you want to set attributes.
3. Press CONFIG, then press CHAN.
4. Select DELAY and set the additional delay to incur after the relay settles. Enter the value for the
delay in seconds. The total delay for channel operation is user delay plus the relay settling time.
