System LEDs

PWR (Power LED)

The Power (PWR) LED indicates the status of the system power. When the system is on, this LED will turn green,

and when the system power is off this LED will be off.

RDY (Ready LED)

The Ready (RDY) LED indicates the status of the system’s kernel. When the LED is green the system kernel is

ready. When the LED is green and blinking, the system’s kernel is booting-up. When the Ready (RDY) LED is red,

there is either a system error or the system is being reset to factory defaults. When the Ready LED is red and

blinking, the device’s factory default mode has been triggered.

Communication LEDs

P1 and P2

The ioPAC controller comes with two serial connections. P1 and P2 represent the status of each serial

connection. When the LED is green, the ioPAC is transmitting data (Tx). When the the LED is amber, the ioPAC

is receiving data (Rx). When the LED is blinking randomly, data is either being transmitted or received. For

example, if P1 is blinking and is green, the ioPAC is transmitting data.

When the LED is off, the serial connection is disconnected.

LAN1 and LAN2

The ioPAC controller comes with two Ethernet ports, with the LAN1 and LAN2 LEDs used to represent the status

of the two connections. When the LED is green, data is transmitting at 100 Mbps. When the LED is amber, data

is transmitting at 10 Mbps. When the LED is blinking, data is being transmitted. When the LED is off, there is

no Ethernet connection, or the Ethernet connection has been disconnected.

Cellular

The ioPAC 5542-HSPA RTU controller supports a cellular (HSPA) communications. The Link LED can detect the

communication status and the cellular signal can detect the signal strength of the cellular connection.

User-Defined LEDs: LED1 and LED2

The ioPAC controller allows the user to custom configure these two LEDs (through the software interface).

Refer to the C/C++ Sample Code Programming Guide for ioPAC RTU Controllers for details.

IEC-61131-3 Compliant LEDs: R/S and ERR

The ioPAC controller supports IEC-61131-3-compliant Run/Stop and Error (ERR) LEDs for ISaGRAF-specific

notifications. These LEDs are not user configurable.

I/O LEDs

The ioPAC 5542 RTU controller has I/O LED indicators that directly display the status of I/Os on the front panel

of the ioPAC 5542 RTU controller.
