Installing the MPA2 Panels
Troubleshooting
9.0 Troubleshooting
Note:
The MPA2 EOL network is AC-coupled. There is no resistance
difference between the RS-485 positive and negative terminals if the EOL
network is on or off (S1, switches 8 and 9).
Table 11 Troubleshooting Problems and Solutions
Problem
Solution
The panel
powers up, but
it does not
respond to any
communicatio
n, cards reads,
or input
activation.
Ensure that the Address DIP switches are set to a value other
than zero. Turn off the power (including battery), change the
settings, and re-apply the power.
No
communicatio
ns exist with
the Ethernet
port.
Only a panel set to be a Primary (DIP switch 3 = ON) will have
communications on the Ethernet port. If you need to use that
port to access the panel, turn off the power (including the
battery), change the switch setting, and reapply the power.
Note that if the panel is normally not a Primary on a Multidrop
communication bus, then the Host RS-485 connection
J17/18 should also be disconnected while DIP switch 3 is ON.
After completion of the Ethernet session, turn off the power
(including the battery), change the switch setting, re-connect
the Host RS-485 terminal block, and re-apply the power.
The panel
address is
unknown.
Option 1: Set the MPA2 panel’s DIP switch 4 to ON. This will
default the IP address to 192.168.1.150.
Option 2: Connect to the panel through the USB port using the
provided USB A to MicroUSB B cable and the USB driver. The
default USB Ethernet IP address is: 192.168.2.150.
Note
USB2 (J2) is micro USB. Jumper on P5 must be not set.
