Click! 320–322 RS-232 to Fiber Installer Quick-Reference Guide
➊
Configure the device
The Click! 320–322 are configured using the DIP switch on one of the circuit boards inside the device. To access the switch:
1 Use a screwdriver to depress the four tabs marked A in the figure to the right. 2 Slide the front portion of the housing out as far as it will go.
The DIP switch is located toward the bottom of the module. Push a switch down to put it in the on position, or up to put it in the off position. By default, all of the switches are turned off when your devices are delivered (shown in light gray in the tables below). Switch Pos. 1

Some of these settings are used to set up network structures. For a point-topoint configuration, use Click! 320 or 322 modules, with no settings changed, or use Click! 321 devices with switch 4 turned on. For information on other network configurations, see the appropriate chapter in the Click! Series User Guide.

➋
Mount the device
The Click! 320–323 mount on a DIN rail. To mount the device, simply hook the lip over the lower edge of the DIN rail, and use a rocking motion to snap the module into place. NOTE: Do not mount over the T-bus.
➌
Wire power and serial communication
Because the Click! 320–322 do not mount over the T-bus, power and serial communications must be wired into the screw terminals on the top of the module. To wire in power: 1 Connect +DC power from a power source (either the cabinet power supply or from a 5-screw terminal block at the far [right] end of a T-bus) to the screw terminal labeled 24V, located on top of the device. 2 Connect -DC to the 0V terminal. To wire in RS-232 communication, connect an RS-232 cable to the DB-9 connector on the faceplate.
➍
Connect the fiber optic cables The Click! 320 and 322 are endpoint modules. They each have one set of fiber connectors, so they can be at the start or end of a fiber optic communication channel. The Click! 321 is a repeater module. It has two sets of fiber connectors, so it can receive and then transmit a signal, extending the length of the communication channel. This module can also be configured to function as an endpoint, as outlined in Part 1 of this document.
NOTE: The Click! 322 uses single-mode fiber, so it can’t be networked together with the other devices, which use multimode fiber, unless it has been configured to use multimode using the DIP switches on the circuit board (see Part 1). Once you have decided how to connect the devices together, attach the fiber optic cables:
The Click! 320 and 321 use ST connectors. Push the cable connector clamp mechanism
downwards, then secure with a quarter turn to the right. NOTE: When connecting devices with ST connectors together via fiber, be sure to cross the transmit and receive lines. The Click! 322 uses SC connectors. Push the cable connector down until it clicks.
