E1/T1 setting
On the older version of the PrimuX 4S2M controllers you will find a header with three pins
for each port. This header allows easy configuration for E1 (Europe) and T1 (United States) S2M
lines. Simply set the provided jumper to the desired position for each port. The PrimuX xS2M
II controllers can be switched between configuration by software.
Jumper settings for PrimuX S0 II
Initially the PrimuX S0 II board is configured for a 33MHz PCI clock. When used in a board with
a 66MHz or higher PCI clock all slots will be clocked down to 33MHz. By removing the '66MHz'
jumper on the PrimuX board the system can run with 66MHz instead.
The PrimuX S0 II NT board generates ISDN line power from the 12V PCI power supply when
configured for NT mode. If you don't need this power for any reason, simply remove the jumper
labelled 'NT Power'.
