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
- Strings (text) are written directly without quotation marks and concluded with CR (hex: $0D) or LF
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
- 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).

Remarks
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. code !
After a menu item is selected by touch, the selected menu item code is transmitted.
is Only transmitted if no touch macro is defined with the number code.
When a bar graph is set by touch, the current value of the bar is transmitted with the
number. Transmission of the bar balue must be activated (see the 'ESC A Q n1'
command).
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 'ESC N T 2' command.
The following is transmitted in the case of a free touch area event: type=0 is release
type=1 is touch; type=2 is drag within the free touch area at the coordinates XX1, YY
After the 'ESC N S' command, the currently selected menu item is transmitted. no=0
no menu item is selected.
After the 'ESC B S n1' command, the current value of the bar is transmitted with the
number nr.
After the 'ESC A X' command, the current status of the touch switch is transmitted
with code (the return code). value = 0 or 1
After the 'ESC A G nR' command, the code of the active touch switch in the radio
group no is sent.
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+")
num = 21 after the 'ESC S I' command, internal information is sent by eDIP (16-Bit
integer values LO-HI Byte) Version: LO-Byte = version number Software; HI-Byte =
Hardware revison letter touch info: LO-Byte = '-|+' X direction detected; HI-Byte = '-|+
Y direction detected DF num: number of user bytes in data flash memory (3 Bytes:
LO-, MID- HI-Byte)
after the 'ESC UH....' command, a hard copy is sent in BH7 Format. xx1,yy1 = Start
coordinates of the hard copy (upper left corner)
