Hardware Installation
2-Port (Serial Terminal) 1E/2E Installation
Use the following procedure to install DeviceMaster 2-port models with serial
terminal connectors. See
2-Port (DB9) 1E/2E Installation
on Page 24 if the
DeviceMaster has DB9 serial connectors.
1.
Attach the DeviceMaster 2-Port to the DIN rail adapter.
2.
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 139 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
3.
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. Refer to
Daisy-Chaining DeviceMaster 2E/4/8/16-Port Units
on Page 168 for more
detailed information.
