Caution

For 1 A current sensing, current shall not exceed 3 amperes for 30
seconds or 4 amperes for 1 second. For 5 A current sensing, current
shall not exceed 15 amperes for 30 seconds or 20 amperes for 1
second. Exceeding the above limits may result in equipment damage.

Notes

1.

If the DGC-2020HD is providing one end of the J1939 bus, a 120

Ω, ½ watt

terminating resistor should be installed across terminals 51 (CAN1L) and 52
(CAN1H) and/or 54 (CAN2L) and 55 (CAN2H).

2.

If the DGC-2020HD is not part of the J1939 bus, the stub connecting the DGC-
2020HD to the bus should not exceed 914 mm (3 ft) in length.

3.

The maximum bus length, not including stubs, is 40 m (131 ft).

4.

The J1939 drain (shield) should be grounded at one point only. If grounded
elsewhere, do not connect the drain to the DGC-2020HD.
