Synchronous Adapters

HSCB Gold adapter

The HSCB Gold adapter provides all of the following services:

• 2 synchronous ports (up to 2,5Mbit/sec)
• 2 housings for the RS232/V24, V35, X21, MAN/V11 piggy back interface modules
• 1 socket for the data compressor processor
• 2 sockets for 30 pin SIMM RAM for the data compressor
• ISA bus

In each Abilis CPX it is possible to plug in only one HSCB Gold adapter.

Figure 6. HSCB Gold adapter.

The JP4 jumpers block selects the IRQ level used by the communication chip (ESCC).

For selecting the given IRQ level, install the jumper in the proper position (a-b).

In the newest version of this adapter the "c " line has been removed to avoid mistakes.

The JP3 jumper block makes possible to direct an IRQ level from the ESCC to the DCP, by changing the proper jumper position from the b-c to the a-b one. Actually the DCP driver doesn't use the IRQ signal, so jumpers must be kept in the position b-c. In the newest models, jumpers have been replaced by welded wires

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

"Piggy-back" interface modules for HSCB and ESB

Each port can support the requested interface module: V24, V35, X2, MAN-V11.

Figure 7. HSCB, modules V24, V35, X21 and Manchester/V11.

Depending on the chosen interface and DCE/DTE modality, it is needed to use the suitable cable, as the following table shows. 

User must insert or extract very carefully the interface modules, without forcing excessively.
Modules have two different size connectors, user must pay attention to insert them in the proper sockets.

If the module is wrongly inserted, the module itself and the adapter will be damaged.

HSCB Silver adapter

The HSCB Silver adapter provides all of the following services:

• 2 synchronous ports (up to 2,5Mbit/sec)
• 2 housings for the RS232/V24, V35, X21, MAN/V11 piggy back interface modules
• In each Abilis CPX it is possible to plug in up to7 HSCB Silver adapter plus 1 HSCB Gold, or 8 HSCB Silver.
• ISA bus

Figure 8. HSCB Silver adapter.

The JP4 jumpers block selects the IRQ level used by the communication chip (ESCC).

For selecting the given IRQ level, install the jumper in the proper position (a-b).

In the newest version of this adapter the "c" line has been removed to avoid errors.

The HSCB Silver adapter makes possible to select the IRQ12 (10 jumpers instead of 9), which is not present in the HSCB Gold one. However some old models are lacking (9 jumpers as the HSCB Gold one). The user is asked to check the presence of the IRQ12, by counting the number of present jumpers.

The HSCB Silver adapter uses the same interface modules and cables as HSCB gold.

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

ESB adapter

The ESB adapter provides all of the following services:

• 4 synchronous ports (up to 2,5Mbit/sec, up to 10Mbit/sec if the "high speed" interface is requested)
• 4 slots for the RS232/V24, V35, X21, piggy back interface modules
• PCI bus

Being a PCI adapter, no jumpers/switches configuration is needed.

Figure 9. ESB adapter.

ESB2 adapter

The ESB2 adapter provides all of the following services:

• 4 synchronous ports (up to 2,5Mbit/sec, up to 10Mbit/sec if the "high speed" interface is requested)
• 4 slots for the RS232/V24, V35, V11, X21, E1/G.703 piggy back interface modules
• PCI bus

Being a PCI adapter, no jumpers/switches configuration is needed.
