E271-2200 AND E271-2210 CONTROLLERS
The E271-2200 and E271-2210 controllers can be jumpered or configured with
software setup for optional software protocols. Emulation can be full or partial.
If J2 is jumpered for ASCII Mode, the standard Touch packet is replaced with the
SmartSet ASCII Mode packet, described in the following section. All other
communication remains the same.
If J10 and J11 are jumpered to select an Emulation Mode, (full emulation), the
controller will no longer respond to the SmartSet protocol. (See page 16.) When
emulating the AccuTouch E271-140 or IntelliTouch E281A-4002 controller, only
one-way communication is possible. When emulating the DuraTouch E261-280
controller, the command set of the E261-280 is supported, described later in this
appendix. This separate command set may also be used to select one of the E261-
280 output formats.
When E271-140 emulation is jumpered, the TouchFlag in the Emulate command is
forced to 0. When E281A-4002 emulation is jumpered, Z-axis scaling is enabled,
with a constant value of 15 being returned. When E261-280 emulation is
jumpered, the scaling range is set to 2-255, and Scaling, Range Checking, and
Trim Modes are enabled. All other jumpers and NVRAM settings, (except the Key
byte), remain available within each emulation mode.
