I'm in the process of building a remote to control a projection system
using a BS2 and I'm having difficulty establishing serial
communication with the device. I know that the projector uses 8 bit,
no-parity and inverted polarity so I think I have my SEROUT command in
the correct format (See Below).
SEROUT 9, 16468, 1000, [2,"AD01:PON",3]
And the ouput data format has been verified as correct by the
projector manufactuer. This leaves me to suspect that there may be a
problem with the wiring. On a DB9 connector I have the pinout going to
pin 2, and the VSS going to pin 5. I have also connected pins 7, and 8
internally. I'm just not sure what to do with pin 3 on the connector.
The projector does not need to communicate with the remote so do I
even need that wire?
I have plugged the cable into a computer and using Hyperterminal I've
been able to recieve the data in the correct format.
Any suggestions as to what may be the source of my problem?
