REN (remote enable)
The remote enable command is sent to the Model 2790 by the controller to set up the
instrument for remote operation. Generally, the instrument should be placed in the remote
mode before you attempt to program it over the bus. Setting REN true does not place the
instrument in the remote state. You must address the instrument to listen after setting REN
true before it goes into remote.
The Model 2790 must be in remote in order to use the following commands to trigger and
acquire readings:
