Overview
Multi-2C/LPCIe is equipped with PCIe to PCI Bridge and SB16C1052PCI, powerful semiconductor designed by SystemBase. The SB16C1052PCI semiconductor is a UART designed for PCI Bus which has the 256 byte FIFO, the largest in the world. There are no overrun when communicating with 921.6kbps. It has all the necessary components for the serial communication that the developers do not require additional components to design the product. There are RS232 and RS422/485 (Combo) models. It is ideal for POS, medical use, factory automation and building automation field.
Power Supply through Pin #9
The Multi-2/PCIe is designed to supply 5 or 12 volt power through pin #9 to power the external device. This function is ideal for connecting low power device such as barcode readers or POS printers, eliminating the need for an external power supply.
Auto Toggling
The Multi-2/PCIe has a built-in hardware feature that performs automatic toggling to prevent devices from sending data at the same time causing a crash. This operation is crucial when multiple devices are connected to prevent electrical collisions that lead to errors and unstable communication.
Slew-Rate Limit Control
The Multi-2/PCIe is equipped with Slew Rate limit control for RS422/485 interface and when enabled it minimizes EMI emissions which may cause data transmission errors. When Slew Rate is used maximum communication speed is 250kbps. This function is recommended in many medical applications.
