This barcode scanner seems to be capable of both rs485 and rs232 hardware standards, and maybe others?
Internally, MAX485 takes DO, DE from and puts DI to the Philips mcu. #RE is taken from the Infineon mcu instead.
(*) LT1180 (rs232 driver) has 2 outputs and 2 inputs, maybe two channels or, most probabily, one channel for TX/RX the other for RTS/CTS signals.
Pin 9 and 14 of LT1180 (should be rs232 TX and CTS) are connected respectively to pin 6 and 11 of ???, an analog switch, then the track gets lost :(
Wiring for Basic functionality
Basic functionality is achieved with this wiring to PC's serial port
RJ45 to scanner | connection to PC or supply |
---|---|
pin 1 | pin 5 of female DB9 and ground of external supply |
pin 2 | pin 2 of female DB9 |
pin 8 | external +5Vcc supply |
Usage
You can find the user manual online.
Barcodes (found in manual) to be used for Reset and setup of rs232 standard mode: SET ALL DEFAULTS and STANDARD RS-232C .
