1 - Introduction
If another keyboard is connected to the same host as this device and a key is pressed on
the other keyboard while this device is transmitting, then the data transmitted by this
device may get corrupted.
Because of potential "data interleave" issues associated with the USB Keyboard interface, MagTek
recommends that this product should only be used if the application requires data to be provided via the
keyboard input.
Third, MICRSafe can communicate with a device other than the host, for instance a POS terminal,
through an auxiliary RS-232 interface. All data is transmitted as ASCII characters (See Appendix E
ASCII Codes). MICRSafe has the capability of supporting some hardware handshaking signals (see
section 4 Legacy Commands). Depending on POS connection port, a 'Mini DIN 9 Pin' or a 'DB9' cable
can be used to connect. Communication in this mode is one-way only, outputting data from MICRSafe to
POS terminal. Baud rate is always set to 9600 bps.
