2. Insert the fiber through the locking nut and into the connector until the core tip seats against the internal

micro-lens.

3. Screw the connector locking nut down to a snug fit, locking the fiber in place.
4. Secure duplex fiber optic cable to wire tie mounting button located on I/O Module circuit board (see

Figure 9-1 on page 73) using wire ties included in parts kit.

Analog Outputs

The

I/O Module

uses two 16-bit isolated analog output channels with 4-20mA and voltage (0-5V/±5V/0-10V/

±10V) outputs supplied from a DC/DC converter. The output voltage ranges are DIP-switch selectable (see

Figure 9-1 on page 73). Analog output configuration is done via setup mode in the indicator used with the

I/O

Module

(see the applicable indicator installation manual).

The analog output circuitry consists of two identical channels that can be assigned to gross or net weight values.

The analog outputs can be configured to operate as either current or voltage outputs. The voltage output range is

selected by configuring DIP switches SW1 (1-6) for channel 1 and SW2 (1-6) for channel 2 (see Figure 9-1 on

page 73).

The analog output port is powered by an isolated DC-DC converter. The outputs available on connector CN1 are

listed in Table 9-8 below. See Figure 9-1 on page 73 for the location of CN1 and DIP switches.
