HDLG-2416 4 digit LED Display Pin numbering

I have a question on a Agilent Tech HDLG-2416 4 digit LED display pin number. The data sheet
only shows pin 1 but does not show a picture of the other pin numbering. I assume that it is the standard counter-clockwise pin numbering ·from pin 1 but the data sheet when it names the pins
has this form;
··· pin·························· ·pin
····· 1···(name)·············· 10· GND
····· 2·· (name)···············11· (name)
····· 3·· (name)···············12· (name)
············· "································· "
····· 9· VDD··· ················18· (name)

These parts cost· $18-$19 a piece so I would like to be sure to get it correct before wiring it up.
I am hoping Paul Baker can come to the rescue again, as after doing a search of the forums
he is the only one I found using them.

Data Sheet

So the question is, do they use the standard pin numbering CCW from pin 1 or is the pin
table in the data sheet the way for pin numbering?

Thanks,
Bob

I believe you are correct it is standard DIP numbering, Ill check my board when I get home to be sure.

When in doubt -- ohm it out.·

Ok it is dip numbering, looking down on the display pin 10 is across from 9, so flip the second column to get the pinout diagram.

PJ itSwatIdid, but metering wouldn't have worked on the individual part, my board shows Vdd connected to upper right (across from pin 1) which means its the /BL pin.
