Txcom1 / Txcom2 (n) 237 [nnn] / 238 [nnn]
Purpose: to transmit a message from serial communications port 1 / port 2.
Remarks: the Txcom instructions transmit formatted page output with n = 1, 2, 3, or 4 (for
pages 1, 2, 3 & 4). The Txcom instructions transmit labels if n = 32, 33, 34, 84, 85, 86, 87
where 32, … = print labels. The print labels can be fixed messages or can be embedded with
register data.
Embedded Code EZ Link Entry Keyboard Entry Comments
any ASCII code nnn nnn = any number 0 - 255
register, min. size 253, rr rr = register number
register, 7 char. field size [reg. name] 254, rr 7 char field, right justified
NOTE1: The indicator waits for COM port 1 to complete its transmission i.e. nothing else is
processed. If COM port 1 is unable to transmit, press the Clear key to exit.
NOTE2: COM port 2 transmits each message using interrupts (the indicator continues
operation while the message is sent in the background). If a second message is sent, COM
port 2 waits up to 2 seconds for the first message to complete. Message 2 aborts after waiting
for 2 seconds. Use ‘Tx2ready’ status check before sending if all messages must be sent or if
sending only if not busy.
Example: all messages sent:
Loop1
If not, Tx2ready
Next1
End if
Txcom2, Label90
Example: send only if not busy:
If, Tx2ready
Txcom2, Lable32
End if
Example: use Print label 34 to transmit ASCII -STX, Net weight, ASCII-CR. Print Net in 7
character field, right justified. Configure Print label 34: <02>[Net]<13>
keyboard entry = 02, 66, 13, 0
F1: Txcom1, 34 transmit print label 34 out serial communications port 1.
