Software Protocols

E261-280 Emulation

Output Formats

The E271-2200 and E271-2210 controllers supports a variety of E261-280 output

formats, including ASCII or Binary, Single-Point or Stream Mode, and untouch

reporting. The default depends on the Output Format and Mode jumpers, J2 and

J4 respectively. The Untouch Flag is included by default. Other output formats

may be selected through software setup when jumpered for E261-280 emulation

mode. All output formats are described starting on page 120.

Software Setup

The E271-2200 and E271-2210 SmartSet controllers emulate the software setup

protocol of the E261-280 controller. Baud rate, output format, axis inversion, and

mode can all be programmed.

Handshaking Sequence

All programming is accomplished through a hand-shake sequence as follows:

Host: <SOH>.....<BYTE1>.....<BYTE2>

280: .....<SOH>.......<SOH>.......<SOH>

The host initiates the sequence by sending an ASCII start-of-header character

(SOH - 01h), then two bytes containing the setup information. The host must wait

for an acknowledging SOH after each character is sent. The controller will change

modes after it sends the third SOH.

Bit Definitions

The bit positions in BYTE1 and BYTE2 above have the following meanings:

BYTE1

Bit Hex Description

0 01 0 = Disable controller readings

1 = Enable controller readings (default)

1 02 0 = Normal operation (default)

1 = Report controller status

2 04 0 = Normal operation (default)

1 = Report firmware revision level

3 08 0 = Required (reserved)

4 10 0 = Required (reserved)

5 20 0 = Required (reserved)

6 & 7 00 Invert x and y axes

1 2 ... 113 114 115 116 117 118 119 120 121 122 123 ... 138 139
