FIGURE 10: JUMPER LOCATIONS FOR E1 CARD
NOTE 1: For 75 ohm E1 card, jumper 9 can be OPEN or ON. If the jumper 9 is
OPEN, BNC connector is set to Unassigned. If the jumper 9 is ON,
BNC connector is set to Chassis Ground.
NOTE 2 : For 120 ohm E1 card, jumper 9 can be OPEN or ON. If the jumper 9 is
OPEN, port 7 and port 8 of BNC connector is set to Unassigned. If the
jumper 9 is ON, port 7 and port 8 of BNC connector is set to Chassis
Ground.
NOTE 3 : BNC is open if jumper 10 is opened, BNC is grounded if jumper 10 is
closed.
NOTE 4: When BNC connector is selected, the user has the option of
grounding the received BNC shield by installing a jumper clip on the
jumper location. This is usually not necessary, but if you have any
noise on your device it can often be filtered out by using this
grounding process.
