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 XG 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.

Table 5-8Rules for Multichannel Responses

Condition	Response	Example

No multichannel	Only the device selected	SYSTem:VERSion?
address used	using the *adr or
	:SYST[<address>]
	:COMM[:MCH]:ADDR
	commands will respond.
Single multichannel	The device addressed in	SYSTem2:VERSion?
address specified	the command will respond
	regardless of if it has been
	selected.			5
ALL or broadcast	Only the device selected	:SYSTem		5
multichannel	using the *adr or	ALL:VERSion?
multichannel	using the *adr or	ALL:VERSion?
address specified	:SYST[<channel>]:C	or
	OMM[:MCH]:ADDR	:SYSTem0:VERSion?
	commands will respond. If	:SYSTem0:VERSion?
	none of the devices have
	been selected then no
	response will be seen.
Multiple	Only the device selected	SYSTem
multichannel	using the *adr or	1,2,4,5,6:VERSion?
addresses specified	:SYST[<address>]
	:COMM[:MCH]:ADDR
	commands will respond. If
	none of the device have
	been selected then no
	response will be seen.
