4-2 Dataliner (DL) Slave Mode
Address
The address of the slave display that will receive the message. This is a
single byte character from 1 to 127 decimal (01 through 7F hex).
Note: Do not use 13 (0Dhex) or 18 (12hex) as an address. These are
reserved and the DL5 automatically converts these addresses to 127 (7F
hex). Address 127 is a global address that accepts all messages regardless
of the address. In addition, any message sent with an address of 127 is sent
to all slave displays.
Line Number
A one byte character specifying the line number the message is to be
displayed on. Valid line numbers are 1, 2, or 50 decimal (not ASCII). The
ASCII characters are Ctrl-A = 1, Ctrl-B = 2, and 2 = 50
Note: 50 decimal as the line number specifies clear both lines.
Carriage Return
Message is terminated by a carriage return, Ctrl-M (decimal 13, 0Dhex).
Example Messages For example, a print statement using a BASIC module (Catalog No.
1771-DB or 1746-BAS) with a DL5 Slave display would be:
The message BLOWER 1 STOPPED would be displayed on line one of
slave number one. To send the message fields, the print CHR (decimal
character equivalent) function is used.
To send the same message from any PC terminal program, use:
Where: ^A is the [Ctrl] and [A] keys pressed at the same time.
^M is the [Ctrl] and [M] keys pressed at the same time.
