Multichannel Address Setting
The power supply multichannel address can be set to any address between
1 to 30. All units that are connected together via the RS-232 or RS-485
connector must have a unique multichannel address.
To set the address:
1. Select the appropriate communication port as described “Selecting
the Appropriate Communication Port” on page 5–20.
If more than one unit has the same multichannel address when
connected through the RS-485 connector, then collisions are possible,
resulting in garbled responses to queries.
2. Press the Rotary knob/Enter button.
ADDR is displayed on the output voltage display.
3. Turn the Rotary knob/Enter button to select the desired multichannel
address between 1 to 30.
4. Press the Rotary knob/Enter button to commit the new address.
Remote Interface Addressing
All commands must be issued with a multichannel address or the device
must be selected using the:
*adr or :SYST[<channel>]:COMM[:MCH]:ADDR commands.
Once a device is selected all commands sent without a multichannel
address will be handled by the selected device. The use of multichannel
addresses supersedes the selected device as the destination for a message.
For more details on how multichannel addresses affect responses, see
Table 5-8.
To change the selected device simply issue the *adr or
:SYST[<channel>]:COMM[:MCH]:ADDR
command with a
different multichannel address. The previously selected device will be
deselected and the new device will be selected. From that point on, all
messages without a multichannel address will be destined for the newly
selected device.
The SCPI Commands for these instructions are:
[:]SYSTem:COMMunicate[:MCHannel]:ADDRess <address>
or
*ADR <address>
