Software Protocols

Mode 06 is like mode 00 in that only a single coordinate is transmitted

upon first touch. The data is in the format:

where <SOH> is the ASCII start-of-header character (hex 01).

Mode 07 - Binary/Single-Point/Untouch Flag J2-N, J4-Y, J10-Y, J11-Y; 1,2

Mode 07 is like mode 01 except the data is transmitted in binary form. The

format is as follows:

Untouch is indicated by the leading <81> character, a <SOH> with the

high bit set.

Mode 26 - Binary/Stream/No Untouch Flag N/A; 0,2

In this mode, coordinates are continuously transmitted until untouch. No

untouch flag is transmitted. For example:

Mode 27 - Binary/Stream/Untouch Flag J2-N, J4-N, J10-Y, J11-Y; 1,2

Mode 27 is like mode 26 except that an untouch packet is also transmitted.

For example:

Like mode 07, an <81> indicates untouch.

When selecting an Emulation Mode, all other jumpers and NVRAM settings are

still available.

E271-141 Emulation

I/O Port Assignments

When in emulation mode, the E271-2201 only has four registers available for

communication with the host processor. Each register is addressed by its offset
