If you can telnet G4.use admin/superuser to login, then use command “bootChange” the set IP.otherwise since G4’s firmware is 3r3 or higher,you are supposed to use RS232 line to change IP.
Can you show me how to do it with the RS232, I couldn’t find the RS232C cable with mini Din-9 plug to fit the G4 serial port. I tried with the DB 9 connect to the mini-9 port with wires, but I don’t know the correct pin map. Thank you!
Pins 1,2,4 NC
Pins 3,5,7 GND
Pin 6 Reset (Act Low)
Pin 8 Serial data in (TTL)
Pin 9 +3.3v
Pin 10 Serial data out (TTL)
You’ll need to convert the TTL serial data to RS-232 levels (+/- insteead of 0/+3.3). I used an NPN transistor and base resistor for input from PC to WS and a PNP, 2 resistors and data out (for negative supply) from a 2nd serial port to get data from pin 10 to PC input. You could use the standard 1488,1489 if you have them. However, I still cannot get the unit to boot even after setting everything on “c” menu. I did do a “C” (capital) and cleared something, was this a bad thing to do??
