Channel Lists

The 87130A can control up to seven different external driver cards, each of which can drive up to 31 different relays. The cards are numbered from 1 to 8; the relays on each card are numbered from 0 to 30. Each relay is referred to as a channel by the switch driver. Therefore, there are a total of 248 relays (channels) that can be driven from a single switch driver.

In order to realize the capability of the switch driver, many of the commands listed in the “SCPI Command Reference” utilize a language construct called a channel list. A single remote command may specify single or multiple relays by means of this channel list.

The syntax for channel lists is as follows:

(@channel number, channel number,...,)

or

(@channel number: channel number,),(a range)

or

(@card number, (channel number, channel number,...,))

or

(@card number, (channel number: channel number,))

or

(@)empty channel list

The card number must always be sent, either as the card number parameter or as part of a channel number (or range). When sent as part of a channel number, the card number is multiplied by 100 and added to the channel number. For example, 214 would mean channel 14 on card 2.

Example (@101,2(0:5),3(1,3,5),406:410)

SCPI Commands

This means channel 1 on card 1, channels 0 through 5 on card 2, channels 1, 3 and 5 on card 3, and channels 6 through 10 on card 4.
