Setting Card Id; Adjusting Termination Of S/T Interface (100 Ohm) - OpenVox B200P User Manual

2.3 Setting Card ID

If want to install more than one card of B200P/BE200P in a PC, you
should take care of the card id switch. The state of ON stands for "1" and
OFF represents "0", Card ID is calculated by binary. For instance, the
four switches should be all set to OFF if there is only one card, which
means their corresponding binary value is "0000" and . There two pieces
of rules you must obey to set Card ID:
 The ID of the first card must be set to 0, and the second should be set
to 1, and so forth.
 The first card is a card that will be initialized (i.e. installing driver)
firstly when the system boot up. At most cases, Linux will initialize
PCI devices according to their slot order. The slot nearest to the CPU
will be initialized firstly and the far end slot will be initialized at last.
That is to say, the card which is nearest to the CPU ID should be set
to 0 if there are more than one B200P/BE200P on your machine.

2.4 Adjusting Termination of S/T Interface (100 ohm)

You are able to set a port to NT or TE mode, please refer to figure 3 for
visualized information.
 If a port works on NT mode, you should set jumper to CONNECT
(ON).
 If a port works on TE mode, theoretically it should be set to OPEN
