Power Supply; Joint Communication And Power Supply In Twisted Pairs, Shielded, Rs485-Cables; 1.2.2 Separate Communication Cable; 1.2.3 Separate Power Supply Cable - Panasonic 5054 Technical Manual

A termination resistor 120R has to be connected in the last unit on the RS485 bus. In 5054
units, this is done via jumper "J7" or "J3". ("J7" shunted = the termination resistor is
connected.)

Power supply

The three tables below are some examples of the minimum cable length and type
requirements to use in display unit wiring.
1.2.1 Joint communication and power supply in twisted pairs, shielded,
RS485-cables
Cable (nearest size)
Belden 1419A, 2pr
Belden 1420A, 3pr
Belden 1421A, 4pr
Belden 1212F, 4pr

1.2.2 Separate communication cable

Communication Cable
Belden 1419A, 2pr
Belden 1421F, 4pr
Belden 7703NH, 1pr
Note: Maximum cable length for communications is 1200 m irrespective of the cable type. Brooks
recommend to use higher gage shielded cables for communications e.g. 0.7 mm² or 1.0 mm².

1.2.3 Separate power supply cable

Power Cable
Belden 5120UL, 14#
Belden 5220UL, 16#
Draka ELQYB, 2x1
Note: As the limitation for communication cable length is max 1200 metre, it is recommended to
use 1.5mm² for the power supplied to display units.
The display unit has two screw terminal blocks for cable connections.
Note: The current consumption of 5054 units is higher than the older style 1728 or 1736. Current
calculation must be performed based on the number of units that can be connected to the FDCIE.
The FDCIE can supply power to a maximum of 4 display units, additional units require external
power supply.

USB Interface

The display unit is equipped with an USB interface (X2) to directly download the firmware
and file system to the display unit via EBLWin.
