Note:

1.The RE-350will shift its mode after the RE-350receives an <Accepted> E-response data from the PC.

The RE-350can not shift its mode to [NOTIFICATION] Mode directly. In order to set RE-350to [NOTIFICATION] Mode, the PC has to give the <Notification> command to the RE-350while in [ON LINE] Mode.

2.After the {RS-232} button is pressed and before the mode of the RE-350is determined, the RE-350will be in a mode transition. To tell this transition status to the operator, the RE-350's RS-232 LED will blink. While the RE-350is in this transition, every button, control knob or command from the PC, will be disregarded.
