IE-CS(T)-2TX-xRS232/485 Getting Started
2-4
Connecting to the Network
Connect one end of the Ethernet cable to the IE-CS(T)-2TX-xRS232/485’s 10/100M Ethernet port and the other
end of the cable to the Ethernet network. If the cable is properly connected, the IE-CS(T)-2TX-xRS232/485 will
indicate a valid connection to the Ethernet in the following ways:
• The Ethernet LED maintains a solid green color when connected to a 100 Mbps Ethernet network.
• The Ethernet LED maintains a solid orange color when connected to a 10 Mbps Ethernet network.
• The Ethernet LED will flash when Ethernet packets are being transmitted or received.
ATTENTION
Every IE-CS(T)-2TX-xRS232/485 is equipped with 2 Ethernet ports, which can be used to create an open
chain of IE-CS(T)-2TX-xRS232/485s. You must be careful not to connect the Ethernet ports of the two
IE-CS(T)-2TX-xRS232/485 at the ends of the chain. In other words, IE-CS(T)-2TX-xRS232/485 does NOT
support a closed chain.
Connecting to a Serial Device
Connect the serial data cable between the IE-CS(T)-2TX-xRS232/485 and the serial device.
LED Indicators
The top panels of all IE-CS(T)-2TX-xRS232/485s have four LED indicators, as described in the following table.
LED Name LED Color LED Function
PWR1, PWR2 red Power is being supplied to power input PWR1, PWR2.
Steady on: Power is on and the IE-CS(T)-2TX-xRS232/485 is booting
up.
red
Blinking: Indicates an IP conflict, or DHCP or BOOTP server did not
respond properly, or a relay output occurred.
When the above two conditions occur at the same time,
check the relay output first. If after resolving the relay output
the Ready
LED is still blinking, then there is an IP conflict, or
the DHCP or BOOTP server did not respond properly.
Steady on: Power is on and the IE-CS(T)-2TX-xRS232/485 is functioning
normally.
green
Blinking: The IE-CS(T)-2TX-xRS232/485 has been located by
S/E-Converter Administrator’s Location function.
Ready
off Power is off, or power error condition exists.
orange 10 Mbps Ethernet connection.
green 100 Mbps Ethernet connection.
E1, E2
off Ethernet cable is disconnected, or has a short.
orange Serial port is receiving data.
green Serial port is transmitting data.
P1, P2
off No data is being transmitted or received through the serial port.
Adjust the Pull-high/Pull-low Resistors and Terminators for
RS-422/RS-485 Ports
In certain critical environments, you may need to add termination resistors to prevent the reflection of serial
signals. When using termination resistors, it is important to set the pull high/low resistors properly so that
electrical signals do not become corrupted. It is improbable for a single pull high/low resistor value to suit all
