Troubleshooting data transmission between Basic Stamp and Transceivers

AI Thread Summary
A project involves integrating a Basic Stamp (BS2P24) with two transceivers, AC4490-200 and CL4490, to transmit data wirelessly. The BS2P24 connects to the AC4490 via specific pins for transmitting and receiving data. Initial attempts to send data using a defined code resulted in failure, despite successful data transmission from the AC4490 to the CL4490 using Aerocomm OEM software. The issue was resolved by adjusting the baud rate and pin configuration for the transceiver. This highlights the importance of correct settings in data transmission projects.

I am working on a project that requires a Basic Stamp (BS2P24) to integrate with two transceivers (AC4490-200 and CL4490). The aim is send data from the BS2P24 to the AC4490 transceiver and then transmit wirelessly to the ground CL4490 transceiver which is connected to a PC. The AC4490 is interfaced to the BS2P24 as follows:

AC4490 pin # Name BS2P24 pin #
2 TXD 0
3 RXD 1
10, 11 VCC -
5,16 GND -


I used the Basic Stamp pins P0 and P1 to connect to transceiver pins 2 and 3 respectively. Then I used the following code to try and send data to the ground transceiver CL4490:

TXpin con 1 ' transmit pin
t9600 con $40F0 ' baud rate is 9600
temp VAR byte

Temp = “A”
SEROUT TXpin, t9600, [temp]

After running the code I was unable to verify that the data was sent to the CL440 transceiver. I’m using the Aerocomm OEM software to try and view the data. However, I’m able to send data from the AC4490 module to the CL4490 using the Aerocomm OEM software (without the Basic Stamp). Any help will be greatly appreciated. Thanks

finally got it to work. just had to cahnge the baud rate and pin # to the transceiver
 

Thread 'Why does the amperage go real high if there is a low voltage short?'

I used to be an HVAC technician. One time I had a service call in which there was no power to the thermostat. The thermostat did not have power because the fuse in the air handler was blown. The fuse in the air handler was blown because there was a low voltage short. The rubber coating on one of the thermostat wires was chewed off by a rodent. The exposed metal in the thermostat wire was touching the metal cabinet of the air handler. This was a low voltage short. This low voltage...

Thread 'How might electronics be different if AC voltage was 72V at 45 Hz?'

Hey guys. I have a question related to electricity and alternating current. Say an alien fictional society developed electricity, and settled on a standard like 73V AC current at 46 Hz. How would appliances be designed, and what impact would the lower frequency and voltage have on transformers, wiring, TVs, computers, LEDs, motors, and heating, assuming the laws of physics and technology are the same as on Earth?

Thread 'How Does Jaguar's 1980s V12 Dual Coil Ignition System Enhance Spark Strength?'

I have come across a dual coil ignition system as used by Jaguar on their V12 in the 1980's. It uses two ignition coils with their primary windings wired in parallel. The primary coil has its secondary winding wired to the distributor and then to the spark plugs as is standard practice. However, the auxiliary coil has it secondary winding output sealed off. The purpose of the system was to provide a stronger spark to the plugs, always a difficult task with the very short dwell time of a...
