CASH DRAWER
In TX-3700 system, the software command to open the cash drawer or the first cash
drawer with the optional 2 in 1 cash drawer control cable is a hexadecimal code of
<07> sent to COM1 port under the protocol of 9600 bps, none parity, 8 data bits, 1 stop
bit.
The software command to open the second cash drawer with the optional 2 in 1 cash
drawer control cable is a hexadecimal code of <17> sent to COM1 port under the same
protocol as above.
The drawer open status can be obtained through checking the communication status of
COM1 at signal RI. When there is no drawer open, the RI signal of COM1 is always
set. When there is any cash drawer opened, the RI signal of COM1 is reset. The RI
signal is obtained as the bit 6 (the second most significant bit) of the I/O address 3FEh
if the COM1 address is set to 3F8h~3FFh (conventional address for COM1) in system
configuration.
