CASH DRAWER

The software command to open the cash drawer is a hexadecimal code of <07>

sent to COM1 port under the protocol of 9600bps, none parity, 8 data bits, 1 stop bit.

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.

during intermittent power failure. This battery is not designed for prolonged power

support to the system against power shutdown. That means, when the AC power

outage is known to last for more than few minutes, it is advisable to turn off the

system instead of using the battery up while repeatedly using it up reduces the battery

life dramatically.

The battery will undergo self-discharging over time even when not in use. An

useful advice to preserve the battery at best condition is to regularly recharge the

battery if the battery or the PST system with the battery is put in storage for a period
