5i25t firmware screwup

I have it hooked up to a 5 volt supply. Lights turn on. Also need to figure out how to make the 7i84 I have get detected when connected to the 7i74. The 84 has 12v field power

The 7i77 must have field power or the field I/O pins will not be present:

hm2/hm2_5i25.0: IO Pin 003 (P3-15): Smart Serial Interface #0, pin tx1 (Output)  << 7I77 analog out is working as it needs only 5V
hm2/hm2_5i25.0: IO Pin 004 (P3-03): Smart Serial Interface #0, pin rx1 (Input)
hm2/hm2_5i25.0: IO Pin 005 (P3-16): IOPort  << This is the 7I77 digital field I/O. It's not working, likely because 7I77 field power is not present
hm2/hm2_5i25.0: IO Pin 006 (P3-04): IOPort
 

I added 12v field power to the 7i77 but still am getting the pin doesn't exist error. I do have a new light on the 7i77 though.

I figure you might ask for the pinout from mesa flash so here is that.

Do you have a red LED illuminated on the 7I77?

With 7I77 field power you should have gotten 2 new LEDs:

yellow LED CR3 and red LED CR16
(when running, red LED CR16 should extinguish and green LED CR15 should blink)

Is W1 in the left hand position?

Oh yes I see only the yellow is on. Red light is not lit on the bottom.

it is in the righthand position for seperate field power from vin. is that vin for the logic seperate from that of the 5v vin on the left hand plug?

I misunderstood the wording in the manual. now that the jumper is over to the right it is lit up and I am making more progress with getting this thing to work.

okay I am now trying to figure out what I need to do to make the 7i74 communicate to the 7i84. it has a pwr LED on and nothing else.

it is in the righthand position for seperate field power from vin. is that vin for the logic seperate from that of the 5v vin on the left hand plug?

The VIN jumper is completely unrelated to the 5V side. Typically it should be left in the default left hand position
so VIN comes from VFIELD. If it's in the right hand position, the VIN pin on TB2 must be supplied with +8 to +32VDC
