Communication Port Configurations
The DPU15000R platform provides several variations of communication ports, such as a 9-pin RS-232, RS-485, and
INCOM
™
. Also available is a list of factory supported common communication protocols for networking the unit.
RS-232 ports are available in two different configurations, Isolated and Non-Isolated. Isolated ports provide isolation
between the communication port and the rest of the relay.
COM 1 port is configured as a non-isolated port only. Units having an MMI display use the RS-232 port on the front
panel as COM 1, thereby permanently disabling the RS-232 port marked COM 1 on the rear of the unit. Units not
having an MMI Display permit the user to select, via P4 jumper setting (F=Front, R=Rear), either the front or rear
(labeled COM 1) RS-232 connectors to act as COM 1.
COM 2 port is a non-isolated configuration and COM 3 port is an isolated configuration. Refer to the following list of
options to select the most suitable configuration.
The DPU1500R series also features ABB’s innovative RS-485 isolated communications capability available when the
optional Auxiliary Communication board is installed. This isolated RS-485 configuration provides superior communication
quality recommended for applications in areas of high electrical noise or that require connecting cables longer than 10
feet (3m).
Figure 12-1: Rear Terminal Blocks and Communication Ports
Use the MMI to change all communications settings, such as baud rate, data bits, parity and stop bits. You can change
settings locally or remotely. If you use a computer or modem to change the settings, be certain that the communications
settings on your equipment match those of the DPU1500R.
Set the communications settings (baud rate, [parity, data bits, stop bits]) for the front and rear ports as follows:
• Front port: 300, 1200, 2400, 4800 or 9600 [n, 8, 1 or n, 8, 2]
• Rear port: 300, 1200, 2400, 4800, 9600 or 19,200 [n, 8, 1 or n, 8, 2 or e, 8, 1 or odd, 8, 1 or e, 7, 1 or n, 7, 2 or odd,
7, 1].
