Hi, im a university student working on a term project involving this product and looking for anyone with experience. Right now im using a dragon-12 development board to attempt to interface this to an hcs12. The problem im having is that i can not get power to the magstripe reader on my board. However i have a friend who built his own serial com port and it provides power to the magstripe reader. The difference between our schematics is that his (which works) has connections to the DTE ready and the Clear to send pins as well as the standard txd rxd and gnd pins. whearas my development board only has the rxd txd and gnd connections.
My question is that does anyone know if this product requires the CTS and DTE connections in order to operate? or is there some voltage logic level it requires that a max232 cannot provide?
thank you for your time
