Communications Protocol

The Communications Protocol function identifies the communications protocol the RealScan 7882 is using. Scan the Diagnostics Mode and Hex 3 programming tags (must be first tags scanned after applying power). Three beeps sound after scanning the Hex 3 tag, identifying the programming tag. Next, the Status Indicator flashes green and a series of beeps sound that identify the communications protocol. Use the following table to determine the communication protocol.

Tone		Communication Protocol
1	Beep (Short high pitched)	OCIA NCR Short / Datachecker
1	Beep	OCIA NCR Long
2	Beeps	OCIA Non-NCR
3	Beeps	IBM 468x (4A)
4	Beeps	IBM 468x (4B)
6	Beeps	RS-232
7	Beeps	OCIA Single-Cable
10	Beeps	Keyboard Wedge
11	Beeps	Casio / OCIA Non-NCR

Scan the Hex 3 tag to repeat; remove power to end.
