Wavetronix CLK-304 Quick-reference Guide

Click 304/305 USB to Serial

INSTALLER QUICK-REFERENCE GUIDE

is document covers the installation and conguration of both the Click 304 RS-232 to RS-485 converter and
the Click 305 USB to serial converter. e steps that follow apply to both devices unless stated.

Mount the device

1

Each device mounts over a T-bus for power and communication:

1 If the device was shipped with the T-bus connector attached, remove the

connector from the module.

2 Snap the connector onto the DIN rail by positioning it over the rail with

the male connector pointing to the right. Hook one arm over the edge of
the DIN rail and press down on the other arm until it snaps into place.

3 Connect the T-bus connector to the rest of the T-bus by sliding them

together until you hear them snap into place.

4 Mount the device onto the DIN rail: position it properly over the T-bus

connector, hook the lip over the lower edge of the DIN rail, and use a
rocking motion to snap the module into place.

Wire power and communication

2

If you are using a Click 200 surge protector, power and communication are provided to the device through
the T-bus (see the Click 200 Quick-reference Guide). If you don’t have a Click 200 surge protector, use the
following steps to wire power and communication into the device:

1 Plug a T-bus 5-screw terminal block into the rst T-bus connector.
2 Wire DC power (10–30 V) from the power supply into the rst

screw terminal on the 5-screw terminal block; wire -DC into the
second screw terminal.

3 Connect +485, -485 and GND to either the remaining three

screw terminals on the 5-screw terminal block or to the screw
terminals in the pluggable screw terminal block on the top of the
device (see labels for correct wiring).

Each device has several other communication ports.

˽ DB-9 connector (both devices) – Connect a straight-through cable for RS-232 communication
˽ RJ-11 jack (Click 304) – Connect a jumper cable for RS-485 communication
˽ USB connector (Click 305) – Accepts a USB 2.0 cable with a B-type plug (covered in Part 4)

yellow LED selects the autobaud process, is on during the autobaud process, etc.

LED activity indicating functions:

Red – Shows device has power

Yellow – Shows device is transmitting data

Green – Shows device is receiving data

option. Follow the steps to install the drivers.

5 Once you’ve installed once, the Found New Hardware box will come up a second time. Follow step 4 again.
