Gantner Instruments Test & Measurement GmbH

3. ASCII PROTOCOL

3.1. Transmission Sequence

In the ASCII-protocol data are transmitted from and to the e.bloxx module by means of the following sequence:

SD .. .. .. .. .. .. .. .. .. ED

request telegram

response telegram

request telegram

: Time between two characters

: Time between request-telegram and corresponding response-telegram

: Time between response-telegram and next request-telegram

You will find the minimum and maximum appearing values for T

, T

and T

and the adjustment range in the following

table 3.1.

Values and adjustment range for the times T

, T

and T

(CT: character time: 1 CT = character length [bit] / baud rate [bps])

Notice:

In the ASCII-protocol T

2max

lasts at least 12 ms.

The values for T

2min

and T

3max

and the behavior of the sensor module if the time T

3max

is exceeded (communication

timeout) can be adjusted by means of the

Configuration Software ICP 100

. The default values for the time T

2min

is 1 CT

and for the time T

3max

60 sec.
