SS7012 Remote Interface Overview

2

Figure 1 shows a block diagram of the SS7012 remote interface.

Operating
principle

Communication between a personal computer and the SS7012 is virtual RS-232
serial communication. While the USB interface is installed as the transmission
route, actual communication uses RS-232.

It is necessary to issue RS-232 commands via the virtual COM port.
When RS-232 commands are issued to the virtual COM port, commands are
sent to the SS7012 in the following order. (For the receipt of data, the order is
reversed.)
