Cable runs in relation to transmission rate
Longer cable runs can be achieved with lower cable capacitance (max. 30 nF/km) and
lower conductor resistance (loop, 115 Ω/km).
Characteristic impedance 150 ± 5 Ω => terminating resistor 150 ± 5 Ω.
For EMC reasons, the D-Sub connector housing must meet the following requirements:
}
Metal or metal coated
}
Cable shield connection on the housing, connected over a wide area

The assignment of the inputs and outputs in the tables below is the default setting ("Con-
nector pin assignment" table, under "Designation"). It can be changed at any time in the
commissioning software (see chapter entitled "Function Description" for details of the ex-
pansion card).

INFORMATION
As an expansion module, the fieldbus junction box CAN Adapter is available
as an accessory to divide the CANopen interface of the PMCtendo DD5 into
two parallel CANopen interfaces.
