Logo programming cable pin out,
From a LOGO! 24R a 230 should be the same.
Adapter I made works fine, No DONGGLE is used...

LOGO unit is upright:
starting upper left pin as #1 (not labelled using convention)opposite side is #6, key is on right side of connector.
1-TTL in Rx Serial
2-Gnd
3-5 volts
4-SDA for card
5-SCL for card
6-TTL out Tx Serial

You will need TTL<->RS232 converter (ie MAX202) powered by pin 3 of LOGO.
Baud rate is 9600, 8bit, even HEX char.

from this post, this are the pinouts for the end LOGO connector.
