These instructions apply to Release 5.0 of the software.
The TokenExpress adapter comes equipped with two slide switches and one
switch block. These switches and switch block allow you to easily
configure the adapter to fit your particular installation requirements.
One slide switch is used to determine the speed setting for your
adapter. This switch may be set at either 4 or 16 Mbps, depending on the
speed of the Token-Ring to which your computer is connected.
The second slide switch is used to select the cabling type that you will
use with your adapter. The STP setting enables output through the 9-pin
connector (DB-9) for operation over Shielded Twisted Pair cabling. The
UTP setting enables the RJ-45 connector and the on-board media filter
for operation over Unshielded Twisted Pair cabling.
The switch block is used to determine the Remote Program Load (RPL)
enable/disable, the RPL address, the interrupt level select, the I/O
address select, and the DMA address select. The possible switch
settings are as follows:
Switch 1 - RPL ENABLE
| On |
EEPROM is disabled (Default) |
| off |
EEPROM is enabled |
Switch 2 - 6 - RPL Address
| 2 |

(Default - CC000-CDFFF) |
| 0 |

(0 = on, 1 = off) |
Switch 2 - 6 set the 8K address space for the RPL EEPROM. The
EEPROM can be placed on any 8K boundary from C0000 to FE000.
Switch 7,8 - Interrupt select

Programmed I/O |
Note: Setting switches 11 and 12 to off forces the driver/adapter to transfer data using programmed I/O. Though not normally used, this setting may be necessary if your computer does not support the AT Bus Master Mode properly.
When the TokenExpress ISA adapter is installed in an 8-bit slot of a
PC/AT, programmed I/O is used regardless of the switch setting.
