ISA Cards

Need serial cards for the ISA bus? Many industrial PCs still use them and we're happy to say B&B Electronics continues to support and stock ISA cards.

These card models can be configured for any I/O address and IRQ. Each port can be independently configured for RS-232, RS-422, or RS-485 data protocol. Each also has the popular RS-485 Automatic Send Data Control feature to transparently enable and disable the RS-485 transmitter as needed. Each port uses a buffered, high speed 16550A UART.

This ISA card, model 3PXCC2A, offers most every option possible in a 2-port serial card.
