Multichannel Commands Explained

The use of multichannel addressing allows you to send messages to one
device, more than one device or to all devices. Any of the remote
interface types can be used to send a multichannel command through the
device that is physically connected to the PC to all the devices, provided
that all other devices are connected to via the RS-485 bus. In order to use
multichannel addressing, the setup of the wiring should be completed as
described in "Multiple Power Supply Connections to RS-485 Bus" on
page 5–15.
All SCPI commands in the XTR support the use of multichannel
addressing; however, only one device can respond to a message.
Responses will be sent according to the conditions set out in Table 5-8.
