Мультипортовая плата VScom PCI-400I (PCI 400S) 4 port RS-232 (DB9M) Serial Adapter
The PCI-400I is designed for RS232, RS422/485 industrial communications. It supports 4 independent RS232, RS422 or RS485 ports. Each port can be configured separately.
In RS485 modes applications enable transmission by simply sending data. This is done by ART (Automatic Receive Transmit Control) intelligence. The Transmitter is disabled exactly with the end of the last character sent. No modification is necessary in programs. The common control by RTS is possible for compatibility. In addition, hardware flow control and built-in termination resistors guarantee data integrity. Surge protection is also available for RS232 Signals to deliver high reliability. All of these features make the PCI-400I suitable for harsh industrial applications.
