GPIO interface 1. Specifications 1.1 GPIO interface is designed for iX4 series printer and external peripheral devices. Figure 1 Installation of iX4 printer 1.2 GPIO interface works in special control by input signals level change, it’s programmable or customized and output signals shown the printer status or functional indicator. Page 1 of 7...

1.3 The GPIO interface is as Figure 2 and Figure 3, it use a D-Sub 15 pin female connector. Figure 2 GPIO board Figure 3 Page 2 of 7...

1.4 Connector pin definitions are as below: Pin No. Type Default Function Description Power return path of +5V Power plus path of +5V. Start to print Start Print When this signal triggered (from high to low), do the print job by command or internal pattern. Feed, when this level of signal in low state, it’s Feed same as panel “FEED”...

2.4 Because all of signals were not isolated, the ground (pin1 and pin8) of GPIO board and signal ground of external device need to connect directly, it should avoid different GND pin connecting GPIO board and make this board fail. 2.5 Suggest the length of connect cable between GPIO interface and external device should less than 15 feet to avoid the noise and error happen.

Figure 5 (3) Pin 5 Pause: a. The signal is make the printer pause action; it is toggle (on/off) mode when printer needs temporary stop or back to standby state. b. When during pause processing, the output pin of Data Ready will active and disable till the pause active again.

Figure 7 3.2 There are 6 output pins for printer’s application; the timing chart is as Figure 8. (1) Pin 10 Serv_Req: a. The signal will active when printer is during normal printing process. b. The timing is same as printer’s printing period. (2) Pin 11 End Print: a.

(6) Pin 15 OPT Fault: a. It indicate all of the printer’s error status, when it active, no function could be executed, please do the troubleshooting process. b. If need to restore the printer function after faults remove, send the “Re-Print” signal (Start Print also synchronous) to do the undone print job, or do last print job again.
