Thread: Re: cash drawer

I would like to re-open this thread.

I am attempting to pop a cash drawer open from an Acer Iconia 500 android tablet (android v3.2) with an on-board usb port that runs in host mode.

When plugging devices such as a mouse, keyboard or cc wedge they immediately function as expected.

The cash drawer can be either a JAY® Electronic Cash Drawer Model 5-135 with an external usb to rj11 adapter
-OR-
a JAY® Electronic Cash Drawer Model 5-130 with onboard usb adapter (comes with drivers providing the functionality below:
The software acts like it is connected through a serial COM port. The POS system application software needs to allow installation & interfacing w/ this open, contemporary interface method.)

So with it being a unix environment I am thinking the following:
1. Mount the device (based on previous peripherals, I believe it will auto mount)
2. Open a connection to device
3. Send Open Drawer Signal/Command
4. Close connection

Please advise.

Thanks in advance

This post had nothing to offer a 2 year old thread, and has been moved to a thread of it's own.

Do you have some question about what you describe here?

jps - Thanks for bumping this into a new thread.

When I implement the openComm class from previous cash drawer thread, I get the following errors in LogCat:
10-11 21:10:26.810: I/dalvikvm(1525): Could not find method javax.comm.CommPortIdentifier.getPortIdentifiers, referenced from method com.MyDomain.MyProject.AppClasses.openPort.main

The methods appear in eclipse Intellisense when typing the command: CommPortIdentifier. however when it runs on the tablet it indicates that it is not found.
