Deltang - Faulty ICs resp. soldering?
Posted: Fri Aug 27, 2021 8:31 am
Hello everyone!
I have purchased a set of Deltang TX2 transmitter and some Rx45-22 receivers. But I can not get the system working. TX and RX sometimes bind, sometimes they don't. I have wired the transmitter according to this schematic:
http://www.deltang.co.uk/dt-tx2-m1-3a.pdf
The only effect I can observe is that the receiver sometimes puts out full throttle electric power to a connected motor when the variable resistor connected to the analog input of the transmitter is turned fully clockwise. After this the motor never can be stopped except from switching off the receiver.
Close before giving up after a week of useless trying I examined the transmitter with a microscope and found that there are solder bridges between certain pins of the larger of the 2 integrated circuits on board the PCB. Here is one example:
The same problem occurs on the other side of the IC (not visible in the picture).
My question: Is it a bug or a feature? Maybe someone has the same transmitter and could check out or I can write a letter to the manufacturer. But just wanted to ask here before because as I have learned from the internet these systems are frequently used for garden railway locos.
Any ideas very much appreciated...
