communication problem between X2 and XBee-Pro RS232

Python

Hey there,

I’m trying to write a python-script to get some projector-stats to my ConnectPort X2,
via XBee-Pro RS232 Adapter.

The scenario:
ConnectPort X2 |- -| Adapter – Controller (RS232) – Projector

The controller sends every 2-3 seconds:
“Uf”

“o.”

If the controller receives a “ta”, during the , the controller sends the projector
information via RS232 to the XBee-Pro Adapter.

My Problem is, that I receive the “Uf” and “o.” messages at my gateway, but there are no further strings. What am I missing here?

Any help would be appreciated!

from socket import *

# The Format of the tuple is:
# (address_string, endpoint, profile_id, cluster_id)
# 
# The values for the endpoint, profile_id, and

# to the serial port on an Ember-based XBee module.
# For 802.15.4 use 0,0,0
BEAMER     = ("[0001]!", 0, 0, 0) 
BEDIENFELD = ("[0010]!", 0, 0, 0)
