Rockwell Automation 2755 Enhanced Decoder Series B - Manual (Page 180)

13–11 Configuration: AUX Terminal Data Entry
Publication 2755-833
If the TM command is sent with a string length of zero (no message
defined), the decoder displays the Default Prompt Message instead.
The following TM command sends the message ”ENTER DATA:” to
the AUX Terminal and enables the keyboard for one entry.
TM111ENTER DATA:
Message Text String = ENTER DATA:
Length of Text String = 11
1 = Enables Keyboard for Data Entry
Command Code = TM
When the host sends this command to the decoder, the following text
string displays on the AUX terminal prompting you to enter data.
The message displays at the beginning of the line in position 01.
ENTER DATA:
If the TM command is sent without a message defined, the decoder
displays the Default Prompt Message instead.
Messages that are longer than the size of the AUX terminal display
truncate.
When receiving the host or default prompt message, the keyboard is
enabled for one entry. Type the data and press [Enter].
ENTER DATA: 123456 [Enter]
After pressing [Enter], the keyboard is immediately disabled until
receiving the next host command. To cancel the data entry operation
without entering data, press [Esc].
Format of Manually Entered Data
After entering data, the decoder sends it to the host. The format in
which the data is sent is controlled by the AUX Data Format
parameter, which is described earlier in this chapter.
PCCC Commands
You can also send a PCCC command to the decoder to display a
message at the AUX terminal and optionally enable the AUX
terminal keyboard.
