8.3 RMT Operation
In the case of communication, the RMT button is used to change the running modes
Change to Local Operation in Remote Control Mode;
Change to Auto Fetch function in Local Operation mode.
NOTE: Auto Fetch means to send testing result automatically without needing the
initiative inquiry of PC.
Remote Mode
Upon the acceptance of any commands from PC, the meter will be automatically set
into remote mode. In this mode, the LCD display will show “RMT” indicator. When
this is shown, all front panel button will be locked and disabled, except for RMT and
POWER buttons. If the meter has been in Auto Fetch mode before receiving remote
control commands, Auto Fetch mode will be terminated.
That is to say, among panel operation, Auto Fetch and Remote Control, remote
control has the highest priority.
To exit remote control, press the RMT button. When the “RMT” indicator disappears
on the LCD display, the meter goes back to local operation.
NOTE: If the local operation is locked, RMT button will be ineffective as well. See
*LLO Common Command in Command section for details.
Be out of remote mode, press RMT button to change to Auto Fetch. See the
description below.
Auto Fetch
When the meter is out of remote control, it can be changed to Auto Fetch mode. That
is, the meter will automatically send data to the interface bus upon every
measurement. Therefore, PC will obtain data by direct reading with no need to send
any commands. It is quite useful in the recording of simple data.
Enable/Disable Auto Fetch
To toggle between enabling and disabling auto fetching when the meter is out of
remote control, press the RMT button. In Auto Fetch, every flash of “RMT” means
send a measurement result.
NOTE: Auto Fetch can be disabled by remote control. When a remote command is
sent to the meter, Auto Fetch will be disabled. To re-enable Auto Fetch after remote
command, first press the RMT button to return panel operation and then enter into
Auto Fetch mode by another press of RMT.
8.4 Command Protocols
Overview
SM6016 employs SCPI commands with ASCII character strings transmitting control
commands and returning query information and data and with a specified terminator
identifying the termination of a command line or query data line.
The adoption of SCPI commands brings convenience for the interaction control of PC
on the meter through programming. Command format is compliance with
specifications and easy for understanding and use.
