RS-232/422/485 Send_String Escape Sequences (Port 2)

This device also has some special SEND_STRING escape sequences:

If any of the 3 character combinations below are found anywhere within a SEND_STRING program instruction, they will be treated as a command and not the literal characters.

In these examples: <DEV> = device.

Example:

 

 

SEND_STRING RS232_1,"27,18,1"

 

Sets the RS232_1 device's ninth data bit to 1 on all character transmissions.

 

 

27,19,<time>

Syntax:

Insert a time delay before

SEND_STRING <DEV>,"27,19,<time>"

transmitting the next

Variable:

character.

time = 1 - 255. Measured in 1 millisecond increments.

 

 

Example:

 

SEND_STRING RS232_1,"27,19,10"

 

Inserts a 10 millisecond delay before transmitting characters to the RS232_1

 

device.
