Summary

The ISDN board SX2 DualPRI V2 needs to be configured before first use. This article gives an overview about the possible configurations.


Information

Before the SX2 DualPRI V2 card is installed into the machine you have to configure the RJ-45 socket pinout and the line termination.

The following description assumes you have the card in front of you with the RJ-45 sockets on the left side and the PCI connector pointing in your direction. Each RJ-45 socket has two jumper blocks assigned. Throughout this description the jumper block containing 2 jumpers is named JB2 and that one containing 5 jumpers is named JB5. A suffix L,R.U or D means that either all jumpers are on the block's left side (L), the right side (R), the upper side (U) or the down side (D), e.g. JB5L means that all jumpers of JB5 are jumpered to the left side.

RJ-45 Socket Pinout

The RJ-45 socket pinout can be changed with jumper blocks JB2 and JB5. It is possible to chose out of 4 different pinouts:

Jumper Block Assignment RJ-45 Socket Pinout
JB2U and JB5R

Pin1 = TX+

Pin2 = TX-

Pin4 = RX+

Pin5 = RX-

JB2D and JB5R

Pin3 = TX+

Pin6 = TX-

Pin4 = RX+

Pin5 = RX-

JB2U and JB5L

Pin1 = RX+

Pin2 = RX-

Pin4 = TX+

Pin5 = TX-

JB2D and JB5L

Pin3 = RX+

Pin6 = RX-

Pin4 = TX+

Pin5 = TX-


Configuration Line Termination

On the right side beneath the jumper blocks you'll find a DIP switch with two pins. This switch is used to select the line termination. If both pins are "OFF" then no termination is present. If the left pin is "OFF" and the right pin is "ON" a 120 Ohm termination is active. If the left pin is "ON" and the right pin is "OFF" a 75 Ohm termination is active.

On the board's lower right side you see a jumper with three pins. Make sure that the jumper is set to position "3V3 reg".

SwyxStandby Support

The board supports the SwyxWare Option SwyxStandby. To activate support for this feature make sure that the jumper between both RJ-45 sockets is plugged in.

Board number configuration

The board number can be set with the four DIP switches located at the upper middle side of the board. The DIP switch on the left is associated to Port 1, the DIP switch on the right is associate to Port 2. The following assignment is valid:

Switch 4 Switch 3 Switch 2 Switch 1 board number
off off off on 1
off off on off 2
off off on on 3
off on off off 4
off on off on 5
off on on off 6
off on on on 7
on off off off 8
on off off on 9
on off on off 10
on off on on 11
on on off off 12
on on off on 13
on on on off 14
on on on on 15
off off off off automatic

Please note that you have to use the numering shown in the picture rather than the numbering on the DIP-switch itself.

Please make sure that you either assign a board number for all boards in the system or configure all boards for automatic number assignment.

PCM bus connection

The board provides two connectors with 20 pins each. Those connectors are used to connect two boards with an optional PCM cable. The upper connector is the output and the lower connector is the input. Connect two boards with a PCM cable by connecting the output of the first board with the input of the second board.

LED Status Monitoring

Each E1 socket has assigned 4 monochrome LEDs as a status monitoring facility.

The following assignment is valid:

LED1 off: Layer 1 de-activated
LED1 red: Layer 1 activated
LED2 green: Layer 2 activated
LED3 green blinking: At least one connection active
LED4 red blinking: The line is being configured
