2-Port (Serial Terminal) 1E/2E Models
Use the following procedure to install DeviceMaster 2-port models with serial terminal
connectors. See 2-Port (DB9) 1E/2E Models
on Page 22 if the DeviceMaster has DB9 serial
connectors.
1. Record the MAC address and serial number of the DeviceMaster unit on the customer
service label provided.
You may need the MAC address during driver configuration. The MAC address (starts
with 00 C0 4E) and serial number are located on a label on the DeviceMaster.
2. Attach the DeviceMaster 2-Port to the DIN rail adapter.
3. Connect the power supply and apply power to the DeviceMaster using the power
supply specifications on the product label and the following information.
Observe proper ESD techniques when connecting and disconnecting the
DeviceMaster.
a. Insert the earth ground
wire into the chassis
ground screw terminal.
The chassis ground
connection is made only
if the DIN rail is NOT
connected to signal
ground.
b. Insert the DC positive
wire into the + screw
terminal and the DC
return wire into the -
screw terminal.
If you purchased the
Comtrol power supply
(separately), the wires
are identified below:
• Red = 5-30VDC
positive
• White = 5-30VDC return
• Black = chassis ground
If you did not purchase a power supply from Comtrol for the DeviceMaster, see 2-
Port (Serial Terminals) Power Supply on Page 88 for power requirements.
c. Use a small flat head screw driver to lock the wires into place.
d. Verify that each wire has been tightened securely.
e. Connect the power supply to a power source.
Note: Do not connect multiple units until you have changed the default IP address, see
Initial Configuration
on Page 33.
4. Use the appropriate method for network attachment of your DeviceMaster 2-port:
DeviceMaster 1E: Connect the 10/100 port to the same Ethernet network segment as
the host PC using a standard network cable.
DeviceMaster 2E: Connect the DeviceMaster 2E using one of these methods:
• Ethernet hub, switch (10/100Base-T), Server NIC (10/100Base-T): Connect
a 10/100 port to the same Ethernet network segment as the host PC using a
standard Ethernet cable.
• Daisy-chaining DeviceMaster units: Connect the port labeled E1 (or E2) on the
first DeviceMaster to the port labeled E1 (or E2) on the second DeviceMaster or
other device using a standard Ethernet cable.
