It turns out there are 2 module boards that connect to the device.\u00a0 The first is the USB module that we currently\u00a0 use.\u00a0 The second is a Serial module that uses RS323 to communicate.\u00a0 Both of these modules connect to the device through a 9 pin connector.\u00a0 However, neither of these modules had any published information specific to board layout, schematics, or even theory of operation.<\/p>\n
I was able to source a RS323 \/ TTL converter<\/a> and a bluetooth module<\/a>.\u00a0 The RS323 module that was made for the device fetches for $175.\u00a0 The total cost of around $225 is more than what I’m willing to shell out for an experiment.\u00a0 I decided to contact the manufacturer of the device to see if they offer a wireless solution.<\/p>\n They wrote back and said that they do not offer a wireless option.\u00a0 I then requested some information about the RS323 module and if any more details about the module were available.\u00a0 I stated my intent of implementing my own wireless option, by means of an adapter.\u00a0 I pointed out that I would need the information in order to spec out the adapter successfully.<\/p>\n The manufacturer responded again that they do not offer a wireless option.\u00a0 They also pointed out that if I were to place an adapter on the device, it could lead to water damage.\u00a0 I responded that I fully understood that water damage could occur if openings were not sealed.\u00a0 I explained that the design would be completely contained, even though the current design has an opening for a USB connection.\u00a0 I haven’t heard back.<\/p>\n Since the risk of damaging outweighs the benefit of identifying the pins of the device’s connectors, this project is getting bagged.\u00a0 It’s not a common trait to be welcomed by a commercial group that guards its trade secrets.\u00a0 I think it’s reasonable that they would want to protect themselves from competition.<\/p>\n At this point, my best effort would be to reverse engineer the USB module.\u00a0 I’ve found some inspiration from some similar efforts<\/a>, but it just isn’t worth it at this point to continue this pursuit.\u00a0 The bonds of the power conglomerate remain.<\/p>\n","protected":false},"excerpt":{"rendered":" It turns out there are 2 module boards that connect to the device.\u00a0 The first is the USB module that we currently\u00a0 use.\u00a0 The second is a Serial module that uses RS323 to communicate.\u00a0 Both of these modules connect to the device through a 9 pin connector.\u00a0 However, neither of these modules had any published information specific to board layout, schematics, or even theory of operation.
