DIP Switch Settings
The DIP switch is on the left side of the Cassette of the Analog Input Unit
(GT1-AD04). Detach the Cassette from the Unit in order to make DIP switch
settings. The following diagram shows the functions of the DIP switch.
The following table summarizes the DIP switch settings. (All pins are factory-
set to OFF.)
Note 1. When setting the input range using a DeviceNet Configurator, use version
1.11 or later. (If pin 10 is ON, and a setting is made using the Configurator,
the input ranges will all be 0 to 5 V.)
2. Before detaching or attaching the Cassette or making DIP switch settings,
ensure that the power supply to the I/O Unit (including power supply to I/O
Unit interface) is OFF.
