Metasys Integrator® MIG3500 Series Installation Instructions4
• The serial ports on the MIG3500 are not labeled
the same as the serial ports on the MIG300. See
Table 1.
• As indicated in Table 1, Port 1 on the older models
is equivalent to the Config Port - RS232C
commissioning port on the MIG3500. When you
commission the device, connect the serial cable
from the computer to the Config Port - RS232C
port on the MIG3500.
• Also indicated in Table 1, Port 2 on the older
models has no equivalent port on the MIG3500. A
device using RS-485 communication can be
connected directly to the Vendor A - RS485 port
on the MIG3500. If the device uses RS-232
communication, an RS-232 to RS-485 converter is
needed before you can use this port; or, you can
use the Vendor B - RS2323C port instead.
• And lastly in Table 1, Port 3 on the older models is
equivalent to the Vendor B - RS232C port on the
MIG3500. A device connected to Port 3 on the
MIG300 can be switched to the Vendor B -
RS232C port on the MIG3500.
• While the MIG3500 is restarting, the LEDs on the
unit indicate its status.
Wiring
Power Supply, Network, and Communication
Connections
See Figure 1 for the location of the power supply
terminal, RS-232 and RS-485 terminals, and Ethernet
port on the MIG3500. For additional information
regarding these connections, refer to the Metasys
Integrator 3500 Series Commissioning Guide
(LIT-12011439).
Power Supply
In North America, the MIG3500 requires a dedicated
Class 2, 24 VAC, 25 VA minimum power supply.
Outside North America, use a 24 VAC Safety
Extra-Low Voltage (SELV) transformer at the
appropriate rating. The minimum input voltage for the
MIG3500 to operate properly is 20 VAC. Maximum
power consumption is 25 VA.
Config Port - RS232C Port
The Config Port - RS232C serial port (Figure 1) is for
a direct connection using a standard 9-pin female to
9-pin female Data Terminal Equipment (DTE) to
DTE null modem cable. Use this port exclusively as a
commissioning port. It provides a VT100 terminal
emulation interface to the unit.
Vendor A - RS485 Network Terminal
The Vendor A - RS485 network terminal is a 4-position
removable, keyed terminal block. Use this terminal for
a vendor device that requires an RS-485 interface.
Vendor B - RS232C Port
The Vendor B - RS232C serial port (Figure 1) is for a
direct DTE connection. Connect to DTE equipment with
a null modem cable or to Data Circuit Equipment (DCE)
with a straight-through cable. Use this port to connect
third-party equipment that requires an RS-232
interface.
N2 - RS485 Bus Terminal
The N2 - RS485 bus network terminal is a 4-position
removable, keyed terminal block. Use this terminal to
connect to MIG3500 to the Metasys N2 network.
Refer to the N2 Communications Bus Technical
Bulletin (LIT-636018) for information and guidelines on
wiring devices on the N2 Bus.
Ethernet Port
The Ethernet connection (10 or 100 Mb/s) is an 8-pin
RJ-45 network port (Figure 1). Use this port only if you
need to load the firmware with the Metasys MIG
Update Utility (MUU) over an Internet Protocol (IP)
network connection. Do not connect the MIG3500 to a
local area network. For information on the MUU, refer
to the Metasys Integrator 3500 Series Commissioning
Guide (LIT-12011439).
