3.4.7 DIP Switches
The AGD155 includes 8 DIP switches to define CAN or Ethernet address offset, to connect a 120
Ω
CAN terminator resistor, to activate firmware download mode, and set other functions. These are
hardware configurations that are typically done only once, during product installation.
The value of the DIP switches, as read by the controller during power on (or reset), can be queried
using ADebugData[4] in Agito PCSuite terminal.

Function
Description
1
CAN Bus Terminator
Set to ON to connect 120
Ω
terminator resistor. Only the last
unit in the CAN network needs to have this set to ON.
2
Force Download
Firmware
Set to ON and power cycle to force the product into firmware
download mode. Otherwise, always keep in OFF state.
3
Force Communication to
Default
Forces the controller to default communication parameters
(bypassing other software parameters in the controller):
Ethernet IP:
172.1.1.101
Ethernet Port:
50000
CAN Address:
64
CAN and RS232/USB baud rates are not affected by this DIP
switch. Requires power cycle or reset.
4-6
CAN/Ethernet Address
Offset
DIP Switch 4 – Most
significant bit
DIP Switch 6 – Least
significant bit
DIP switches 4-5-6 create a three-bit value.
For example, if DIP switch 4 is set to ON (value of 1), and 5 and
6 are set to OFF (value of 0), the result is: 100 (binary),
meaning a value of 4.
This value (referred to as
offset
) is used to define the drive’s
CAN bus address and Ethernet IP address as follows:
Ethernet IP
: the actual fourth number of the IP address is equal
to:
EthernetIP [4] +
offset
CAN address
: the actual CAN address of the unit is equal to:
C
offset
* 16
Note: Requires power cycle or reset.

Reserved for Future Use Always keep at OFF state.
8
Reserved for Future Use Always keep at OFF state.
