2.9.1 Serial interface specification
The serial interface of CX400 printer is a RS-232C port with standard 9-pin (DB9-S) connector located at the rear of the printer.
CX400 printers employed “Flow Control” mechanism with either RTS/CTS or X-on/X-off (control characters are DC2
and DC4).
The parameters can be set by printer are as followings,
Speed: 9600, 19200 or 38400 baud
Parity: Odd, Even, or None
Data Bits: 7 or 8 bits
Stop Bit(s) 1 or 2 bits
Default parameters: 9600 bauds, no parity, 8 data bits, 1 stop bit
Pin Signal Description
1
Carrier Detection
“Shorted with Pin 9” ( RI ) or” Open” count on R94 existed or not
0 Ohm on R94 è Shorted with Pin 9 (+5 V )
No Resistor on R94 è Pin 1 is N.C.
2 Received Data, RxD Input. Serial “Received Data”
3 Transmitted Data, TxD Output. Serial “Transmitted Data”.
4 Data Terminal Ready, DTR Always maintai n at high state ( +10 V )
5 GND Signal Ground
6 Data Set Ready, DSR Shorted with Pin 4 (DTR)
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
Ring Indicator, RI
“5 Volt” or “N.C. selected by JP1 on board
“0 ohm “ puts on JP1 è “5 V”
No resistor on JP1 è NC

Note:
CX400 printers require a “null modem” cable (pin 2-3 and 7-8 crossed wiring) while connecting to another DTE
Device, like PC.
