When Power is Applied the OIT’s Display is Blank and the OIT
Beeps
This indicates that the OIT does not contain a complete project and that the OIT is in
download mode waiting for STEPware-100 to download a project. Refer to the STEP1
Protocol Operation Manual - Chapter 1: Getting Started for instructions on creating and
downloading a STEPware-100 project.
The OIT Will Not Enter Configuration Mode
If, instead of displaying Parameters? MODIFY, the OIT displays Disp View Angle: or
Baud Rate:, Local Setup Access has been disabled. You will need to enable Local Setup
Access by connecting the OIT to a host controller and having the host controller send the
Keyboard control command to the OIT. Refer to Appendix A: Control Commands for
more information.
If, for some reason, you cannot reenable the Local Setup Access using the Keyboard
Control command, perform the following:
1. While pressing and holding down the CLEAR or ENTER key, cycle power to the
OIT. Continue pressing until the OIT displays Disp View Angle:, then release.
2. Press the ENTER key to display the Baud Rate: message.
3. Press the B key.
4. Press the I key.
5. Press the P key.
6. Wait for a few seconds. The OIT will reinitialize, allowing you to enter Local Setup
by holding down the CLEAR or ENTER key.
7. Refer to Chapter 1: OIT Configuration and follow the instructions.
