Program Entry Procedure (Shortcut Method)
The following example is a typical program entry procedure.
1. Disconnect scanner from the host terminal.
2. Apply power to the 7893 (or scan the Reset tag).
3. Scan the Program Mode tag.
4. Scan the two Hex tags corresponding to the worksheet number.
5. Scan specific parameter tag (Hex A–F).
6. Scan appropriate Hex tags to enter parameters.
7. Repeat steps 4 thru 6 until all the parameters are entered.
8. Scan the Save and Reset tag. All parameter changes are saved and 7893 is reset (goes
through initial power–up sequence). The 7893 now operates using the new program.
