Responses of the EA eDIP320-8
Remarks
automatic responses
Response from the analog touch panel when a key/switch is pressed. code = down or up
code of the key/switch. it is Only transmitted if no touch macro is defined with the no. cod
ESC N
1 code
After a menu item is selected by touch, the selected menu item code is transmitted. it is
Only transmitted if no touch macro is defined with the number code.
ESC B
2
no value
When a bar graph is set by touch, the current value of the bar is transmitted with the num
Transmission of the bar balue must be activated (see the 'ESC A Q n1' command).
ESC T
0
if automatic opening of a touch menu is disabled (see the 'ESC N T n1' command), this
request is sent to the host computer. The host can then open the touch menu with the 'E
T 2' command.
ESC H

type
xLO
xHI

yHI
The following is transmitted in the case of a free touch area event: type=0 is release; typ
is touch; type=2 is drag within the free touch area at the coordinates XX1, YY1
Response only when requested by command
ESC N
1
no
After the 'ESC N S' command, the currently selected menu item is transmitted. no=0: no
menu item is selected.
ESC B
2
no value
After the 'ESC B S n1' command, the current value of the bar is transmitted with the num
nr.
ESC X
2 code value
After the 'ESC A X' command, the current status of the touch switch is transmitted with c
(the return code). value = 0 or 1
ESC G
2
no code
After the 'ESC A G nR' command, the code of the active touch switch in the radio group
sent.
ESC V num
String...
After the 'ESC S V' command, the version of the edip firmware is transmitted as a string
(e.g. "ea edip320-8 v1.0 rev.a tp+")

USING THE SERIAL INTERFACE
The operating unit can be programmed by means of various integrated commands. Each command
begins with ESCAPE followed by one or two command letters and then parameters.
There are two ways to transmit commands:
1. ASCII mode
- The ESC character corresponds to the character ‘#’ (hex: $23, dec: 35).
- The command letters come directly after the ‘#’ character.
- The parameters are transmitted as plain text (several ASCII characters) followed by a separating
character (such as a comma ‘,’) - also after the last parameter e.g.: #GD0,0,319,239,
- Strings (text) are written directly without quotation marks and concluded with CR (hex: $0D) or LF
(hex: $0A).
2. Binary mode
- The escape character corresponds to the character ESC (hex: $1B, dec: 27).
- The command letters are transmitted directly.
- The coordinates xx and yy are transmitted as 16-bit binary values (first the LOW byte and then the
HIGH byte).
- All the other parameters are transmitted as 8-bit binary values (1 byte).
- Strings (text) are concluded with CR (hex: $0D) or LF (hex: $0A) or NUL (hex: $00).
No separating characters, such as spaces or commas, may be used in binary mode.
The commands require no final byte, such as a carriage return (apart from the string $00).
