DI3270 Bisync is a full-featured micro-to-mainframe connectivity product able to operate standalone or as a gateway between an IBM host and a micro-based local area network communicating via 3270 binary synchronous protocol. DI3270 Bisync supports four concurrent host sessions in a standalone configuration and from 8 to 32 sessions (or user workstations) in a LAN gateway configuration. Maximum data transfer speed between DI3270 Bisync and the IBM host is 19.2Kbps, though actual performance will depend on the capabilities of the bisync adapter board, modem, and phone line. DI3270 Bisync supports point-to-point and multipoint connections.

DI3270 Bisync supports ICOM's full complement of gateway support features, including gateway management; support of multiple gateway environments; and automatic load balancing.

TN3270 Access
In a gateway configuration, the DI3270 MultiProtocol Comm Server can support access from any TN3270 or TN3270E terminal emulator, regardless of host connect protocol.   In the case of DI3270 Bisync, this means that any TN3270-compatible emulator can be used to access a "bisync" host, including  Attachmate Extra!, Wall Data Rumba, WRQ Reflection, and Zephyr Development Passport, to name a few. 

Bisync Adapters
DI3270 Bisync runs on DI's PC-MPA-01 MultiProtocol  Adapter, IBM's bisync adapter [IBM part number 1501204 or 1502075] or compatible.  The IBM bisync board uses IRQ 3 and 4 and I/O addresses 3A0h-3A9h.   These settings are not modifiable.  The multiprotocol adapter does have configurable IRQs and I/O addresses.
