ARGOX printer RS-232 port is DB-9 female port. User should follow the Argox define pin when using RS-232 port.

The RS-232 connector on the printer side is a female, DB-9.

Pin Signal Description
1 No function Shorted to Pin – 6
2 Received Data, RxD Input. Serial “Received Data”
3 Transmitted Data, TxD Output. Serial “Transmitted Data”.
4 No function No connection
5 GND Signal Ground
6 No function Shorted to Pin – 1
7 Request to Send, RTS Output.  Used as the control signal for “H/W Flow Control “
8 Clear to Send, CTS Input. Used as the control signal for “H/W Flow Control”
9 +5V Output. Pin 9 is reserved for KDU (keyboard device unit)

 

Note:     Pin 9 is reserved for a KDU (keyboard device unit). Do not connect this pin if you use a general host such as a PC.

 

 

 

  • Connection with Host:

 

Host 25S Printer 9P       Host 9S Printer 9P
(PC or compatible) (PC or compatible)

 

DTR 20 …… 1 DSR DTR 4 …… 1 DSR
DSR 6 …… 6 DTR DSR 6 …… 6 DTR
TX 2 …… 2 RX TX 3 …… 2 RX
RX 3 …… 3 TX RX 2 …… 3 TX
CTS 5 …… 7 RTS CTS 8 …… 7 RTS
RTS 4 …… 8 CTR RTS 7 …… 8 CTS
GND 7 …… 5 GND GND 5 …… 5 GND

 

Alternatively you can connect the 3 wires as follows:

 

Host 25S Printer 9P       Host 9S Printer 9P
(PC or compatible) (PC or compatible)

 

TX 2 …… 2 RX TX 3 …… 2 RX
RX 3 …… 3 TX RX 2 …… 3 TX
GND 7 …… 5 GND GND 5 …… 5 GND
pin 4 pin 4
pin 5 pin 6
pin 6 pin 7
pin 20 pin 8

 

 

The simplest way to connect to other hosts (not PC compatible) or terminals is:

 

Printer   Terminal/Host
Pin 2- RxData ……… TxData
Pin 3- TxData ……… RxData
Pin 5- Ground ……… Ground

 

In general, as long as the data quantity is not too large and you use Xon/Xoff as flow control, it will be problem free.

 

Baud rate:      1200, 2400, 4800, 9600(default), 19200, 38400, 57600,115200 bauds. (Programmable by command)

 

Data format:  always 8 data bits, 1 start bit and 1 stop bit.

 

Parity:            always non parity

 

Handshaking:        XON/XOFF as well as CTS/RTS (hardware flow control).

 

If you run an application with the bundled printer driver under

Windows and use the serial port, you should check the above parameters and set the flow control to “Xon/Xoff “or “hardware”.
