RS232C SERIAL INTERFACE SIGNALS

PIN

DIRECTION

SIGNAL DEFINITION

1

Reference

FG (Frame Ground)

2

To Host

TD (Transmit Data) - Data from the printer to the host computer. Sends X-On/

 

 

X-Off characters or status data (bi-directional protocols).

3

To Printer

RD (Receive Data) - Data to the printer from the host computer.

4

To Host

RTS (Request to Send) - Used with Ready/Busy flow control to indicate an

 

 

error condition. RTS is high and remains high unless the print head is open (in

 

 

this case, RTS would return to the high state after the print head is closed and

 

 

the printer is placed back on-line) or an error condition occurs during printing

 

 

(e.g., ribbon out, label out).

5

To Printer

CTS (Clear to Send) - When this line is high, the printer assumes that data is

 

 

ready to be transmitted. The printer will not receive data when this line is low. If

 

 

this line is not being used, it should be tied high (to pin 4).

6

To Printer

DSR (Data Set Ready) - When this line is high, the printer will be ready to

 

 

receive data. This line must be high before data is transmitted. If this line is not

 

 

being used, it should be tied high (to pin 20).

7

Reference

SG (Signal Ground)

20

To Host

DTR (Data Terminally Ready) - This signal applies to Ready/Busy flow control.

 

 

The printer is ready to receive data when this pin is high. It goes low when the

 

 

printer is off-line, either manually or due to an error condition, and while

 

 

printing in the single job buffer mode. It will also go low when the data in the

 

 

buffer reaches the buffer near full level.

NOTE: Pin assignments begin with one (1) in the upper right corner and ascend to thirteen (13) in the upper left corner. Pin number fourteen (14) picks up in the lower right corner and ascends to twenty-five (25) in the lower left.

* This connection at the host side of the interface would depend upon the pin that is being used as the Ready/Busy signal by the driving software. Typically, on a PC, it would be either CTS (pin5) or DSR (pin 6) on a DB-25 connector.
