The switch setting is ok on the image.

bella:pin40 --> switch --> r4:1kohm --> max232:pin12
bella:pin39 --> switch --> r3:1kohm --> max232:pin10

(max232:pin9 is dtr/reset!)

db9:pin2 --> mini-din:pin6 --> max232:pin7 (RxD Receive Data)

db9:pin4 --> mini-din:pin5 --> max232:pin8 (DTR Data Term Ready)
db9:pin5 --> mini-din:pin3 --> GND

Is correct: Pin 10 is VSS/GND and has on all chips a connection to Pin 9 (BOEn).

Correct: the capacitor between vdd (pin12) and vss (pin9).

Q1 and IC4 (EEPROM for bella) is for the identification and the led-no test required! Q1 used without the propeller its internal oscillator. Without EEPROM (IC4), you can only test the program began-ram (f10 in the propeller tool). Later for the Videotests Q1 is needed.

What would I test:

1. Connections from DB9 to MAX232 over the MiniDIN.
2. Values of the components around the MAX.
3. Voltage at the sockets from Prop (3,3V) and MAX (5V)
4. What a type transistor t1? (npn-typ needed)

switch - ok
prop sockets - OK
Q1 (5 MHz crystal) - Not required - defaults to internal
IC4 (EEPROM for bella) - not required - uses RAM only
transistor t1 - NPN - OK
Voltage at the sockets from Prop:pin12& (3,3V) -3.28 & 3.29 - OK
Voltage at the sockets from and MAX:pin16 (5V) -5.05 & 4.97 - OK
bella:pin40-switch-r4:1kohm-max232:pin12 - VOM reads 972 ohm
bella:pin39-switch-r3:1kohm-max232:pin10 - VOM reads 976 ohm

Cable was an error, wired backwards, could this have damaged something?
corrected to this:
db9:pin2 --> mini-din:pin6 --> max232:pin7 (RxD Receive Data) (and VOM continuity beeps once on 8, due to capacitor?)
db9:pin3 --> mini-din:pin8 --> max232:pin13 (TxD Transmit Data)
db9:pin4 --> mini-din:pin5 --> max232:pin8 (DTR Data Term Ready) (and VOM continuity beeps once on 7, due to capacitor?)
db9:pin5 --> mini-din:pin3 --> GND, 11, 15

Although on the second board,
DP9 pin2 registers continuity on MAX232:pin7 but does NOT beep once on pin 8
db9:pin4 registers continuity on MAX232:pin8 but does NOT beep once on pin 7
The only difference is this board does not have the HB LED resistors installed yet.

Performing Prop Tool Test....
Prop tool does not identify either unit.
Verified the PC's two comm ports and the serial to USB adapter are functioning

test: Values of the components around the MAX.

I'm going to assume the power supply is correct since the voltages are correct, and I am using a parallax supplied power adapter. C1 and C3 are 100uF 16v. c29 c30 are (100 nF) 0.1 uF 25v.

The four electrolytic capacitors c4, c5, c6, and c7 are 1uF 50v. Is 50v too high?

the ceramic capacitors c8 is (10 nF) 0.01 uF 50v, is 50volt too high?

The ceramic capacitors c15, c16, c17 are are (100 nF) 0.1 uF 25v. If all three of these are installed, do all three prop chips need to be installed? Did leaving the other two sockets empty damage the bellatrix prop?

> Cable was an error, wired backwards, could this have damaged something?

Where exactly was the mistake? The circuit works well, but it is
not rule out an error that leads to damage.

Strength at a higher voltage capacitors is not a problem.

It takes only one chip ( in this case bellatrix) to be plugged.

The circuit (MAX232) has to work - it is often tested - or there is something defective.

Do you have a possibility of a direct serial interface to test - without an adapter cable?
