|
| The 3087 ISA serial interface provides two RS-232, RS-422, or RS-485 Asynchronous links to data collection and other devices. Fully independent operation of ports allows the configuration of the 3087 with either two RS-232 ports, two RS-422, RS-485 ports or with a combination of one RS-232 port and one RS-422, RS-485 port. Extended ""AT"" interrupts allow multiple serial ports to be assigned to different IRQ lines. For user's that require custom baud rates, isochronous communications, or 9-bit protocol, the 3087 ISA serial interface is available with the Oxford 16C950 UART, part number 3087-SN. |
