Re: [time-nuts] Vectron OCXO 204-8888

[Andrea Baldoni]

Hello all.

A friend just made me notice that I should read pin numbers clockwise, he has
an older but very similar unit made by "Electronic Research Co." with number
marks. Besides pin numbering, he too hasn't any information.

So, this is the updated pinout:

1 NC
2,3 GND (but there's not any wire connected to 2 and 3 in my case)
4 black wire (8.5k to GND)
5 red wire (7.6k to GND)
6 white wire (47k to GND) (probably EFC in)
7 white/black wire GND

Best regards,
Andrea Baldoni

Hello,

it seems that I have an similar (?) unit here. It says:
ELECTRONIC RESEARCH CO
EROS-800-A1
AMD135-30698
5.00 MHz
S/N 23   Date Code 90-10

Same dimensions but other pinout: 
It has two coax cables attached

Pin 1 NC
Pins 2, 3 and 7 are GND
Pin 4 Coax cable center, no connection
Pin 5 Coax cable center connector with 8.3 kOhms to GND

There is a SMA connector which probably is 5 MHz output

Unfortunately I don't have any data on it. 

I would appreciate any data about it.

Best regards

[time-nuts] Vectron OCXO 204-8888

[Andrea Baldoni]

Hello!

Anyone knows anything about the Vectron Model 204- (P/N A23652)?
It's a 5MHz OCXO, perhaps DOCXO, with SMA output and a 7 circuit 45 degrees
1 cm diameter round connection block with solderable pins, similar in shape to
the inside of a DIN connector.

At the moment, proceeding counterclockwise, pin 1 (connected to case GND) has
a white/black wire, pin 2 has a white wire, pin 3 a red, pin 4 a black, 5, 6, 7
NC.

If pinout and voltage are known, it would be nice, prior to start
a trial and error procedure.

The unit is a parallelepiped, 51x51mm base, 101mm high, with round corners.
Connectors are on the base, on the opposite side there is the screw covered hole
with trimmer.

On photos of identical units found in Internet, I see:
sticker CRYST.OSC.ASSY 00500-B43024-1
sticker CRYS/ISOL ASSY 00500-B43024-1
wire B50858-1
