Asynchronous adapters

2 ports multiserial asynchronous adapter

The 2 ports multiserial asynchronous adapter has the following interface and provides the following services:

• 2 asynchronous ports up to 115.200 bit/sec
• UART 16650, 32bytes receiving and transmitting fifo
• RTS/CTS Flow control and XON/XOFF managed by hardware
• 1 SIMM slot for RS232/V24, RS422 or current-loop interface modules
• 2 DB9-M standard PC-AT connectors 
• ISA bus

In each Abilis CPX it is possible to plug in up to 4 of such adapters.

Figure 10. 2 ports Dflex Multiserial.

The jumper JP2 must be opened.

The JP1 jumpers block selects the IRQ level used by the adapter.

To select the requested IRQ level, install the jumper in the suitable A position. No jumpers have to be installed in the position B.

For correct jumpers/switches configuration, it also depends on the software one, refer to the chapter Ports numbering and adapters configuration.

8 ports multiserial asynchronous adapter

The 8 ports multiserial asynchronous adapter has the following interface and provides the following services:

• 8 asynchronous ports up to 115.200 bit/sec
• UART 16650, 32bytes receiving and transmitting fifo
• RTS/CTS Flow control and XON/XOFF managed by hardware
• 4 SIMM slot for RS232/V24, RS422 or current-loop interface modules
• 8 DB9-M standard PC-AT connectors, using the adapting cable 
• ISA bus

In each Abilis CPX it is possible to plug in up to 4 of such adapters.

Each adapter is provided with a special adapting cable that has 8 DB-9 male connectors, according to the standard PC-AT.

The JP1 jumpers block selects the IRQ level used by the adapter.

To select the requested IRQ level, install a jumper in the suitable A position. No jumpers have to be installed in the position B.

For correct jumpers/switches configuration, it also depends on the software one, refer to the chapter Ports numbering and adapters configuration.
