VLT is a registered Danfoss trademark
Power switch.
Two position on/off power switch.
Portal address label.
Identifies factory-set or default portal
addresses.
Port connectors label
. Identifies factory-settings for
communication ports 1 and 2. Default setting for port 1 is
unassigned. Default setting for port 2 is EIA-485.
24 VAC connector.
Input power for BACLink module.
Format button.
Normally not used with BACnet. Contact the
Danfoss Graham service department for information on its use to
clear factory-set programming.
Address rotary switches
. Rotary switches used to set BACLink
portal network addresses. Set addresses 01-99 with DIP switch 5
in the +0 position. Set addresses 100-199 with DIP switch 5 in the
+100 position.
Port 1.
Preferred port for ARCnet connection. Selectable for
ARCnet or 2-wire EIA-485. Set DIP switch 4 (Port 1) to
Other
to
enable linking drives with EIA-485 wiring. Set DIP switch 4 (Port
1) to
ARC156
for use as ARCnet connector. (See DIP switches.)

LED indicators
. Status indicator lights for functions as labeled.
Access port
. Utility port for factory programming, set up, and to
assign the IP address. The access port cannot be used as a
communication point or to download memory to the BACLink.
DIP switches
. Two position switches used to enable selection of
IP address, module address, and network type. Sw1 and Sw2
are disabled in VLT communication applications.
Keypad/Display port.
Access port for optional keypad.
Port 2.
Preferred port for EIA-485 connection to the VLT drives.
The terminal is jumper selectable for 2-wire/4-wire EIA-485 or
EIA-232. Default setting is EIA-485 (2-wire).
Port 2 configuration jumpers
. Jumper placement determines
the configuration for EIA-485 (2-wire), EIA-485 (4-wire), or
EIA-232 communication for Port 2. Default is EIA-485 2-wire.
Ethernet port.
Ethernet network connector supports 10baseT
network communication with BACLink.
