Enhanced ISA-EISA 5250 Display Station Emulation Adapter
(FRU P/N 82G7061 for use on ValuePoint-systems recommended)

It supports connection (installed in an VP system) to



In a TWINAXIAL environment. It can be installed in a half or a full-sized slot of an IBM VP.

The adapter ROM-address is D300h

Switch setting

Access to the Enhanced 5250 Display Station Emulator Adapter is obtained using the I/O port addresses. The I/O port addresses that the adapter responds to are determined by the switch settings on the adapter. The switch settings that are set at the factory use I/O port addresses 2718-271F. These values do not normally need to be changed. If you need to change your switch settings because another adapter is using the same I/O port address, then see below tables. In this tables a 1 indicates that the switch is set ON, a 0 indicates that the switch is set OFF.

NOTE: Some older ISA bus adapters and personal computers decode only the ten low order bit portion of the I/O address. These personal computers and adapters can unexpectedly respond in the I/O address range used for the 5250 adapter, even tought the 5250 adapter appears to use a different I/O space.

For example, if serial port 1 assigned to 3F8-3FF I/O addresses and the 5250 adapter is assigned to 27F8, a write to reset the 5250 adapter at address 27FE would also write to serial port address 3FE causing unpredictable results with the serial port.

The Alternate Response Address shows how the 5250 address range is interpreted when only the ten low order bit portion of the I/O address is decoded by older personal computers or adapters.

A bloc of 8 switches is present on the Adapter Card, the preset switches 1 & 6 must stay in the ON position. (Switch 7 and 8 should be set to OFF)

Problem Determination

The OPTION Diskette contains diagnostics. The D5250cc.DGS file and RECFGcc.EXE file ('cc' means the country language) must be copied, onto the diagnostic diskette.

Some problems did occur with the first 5250 Enhanced adapters when the twinaxial environment was a little bit sensible. A new 5250 card is available to correct this, under the FRU P/N 82G7061 , identifiable generally with the P/N 82G7060 writing on the card. (All options shipped after second part of 1993 are normally updated.)
