On the Interface board are located two LED’s:
• Green LED showing the status of the Interface:
- Fast Blinking: 2 times/sec = Interface is Master (1
st
Cabinet of a parallel System)
- Slow Blinking: 1 times/sec = Interface is Slave ( 2
nd
,.. 6
th
cabinet of a //- System)
• Red LED Board Alarm (indicates a possible replacement of the board)
On the Master cabinet the following ports of the customer interface board are active:
• The Input ports (X3)
• The Output ports (X2)
• The Interlock function (X1)
On the Salve cabinet(s) following ports of the customer interface board are active:
• The Input ports (X3)
• External Output Breaker (X2 9/10) and External Manual Bypass (X2 7/8)
All other ports on the Salve cabinet(s) are inactive.
5.3 JD1 / RS232 PC / Laptop Interface
The
Computer Interface JD1
located on the distribution part is an intelligent RS 232 serial port that
allows the UPS system to be connected to a computer. The connector JD1 is a standard D-Type, 9-
pin, female.
It is used to download system event log and to make firmware upgrades.
5.4 USB PC / Laptop Interface
The
Computer Interface USB
has the same function as the RS 232 serial port
JD1
. Use either USB
or RS232 but not both at the same time.
5.5 JR2 / RS232 Interface for Multidrop
The
Computer Interface JR2
(RJ 45 connector) located on the distribution part is the Multidrop
connection which is needed for multi-cabinet configurations. To enable the Multidrop communication
between cabinets it is necessary to set
JP2
jumper correctly on the customer interface board as
shown in the table here below.
Customer Interface Board, PCB NW22085D (with ROM76-12) or NW22085E or later versions
First unit (Master)
JP2 = OFF
Middle Unit (Slave)
JP2 = ON
Last Unit (Slave)
JP2 = ON
Note:
on the (older) versions NW22085
B/C
without ROM76-12 make a bridge between X3-11
& X3-12.
