CL4490-1000-232, CL4490-1000-485, CL4490-1000-PRO v1.1

The goal of this guide is to outline how to configure the CL4490 ConnexLink units with the most basic settings to establish a

Point-to-Point (P2P) or Point-to-MultiPoint (P2MP) connection between two or more CL4490 units.

Note: CL4490-1000-PRO requires slightly different steps to configure due to the DIP switches. These instructions are

covered in Configure DIP Switches (CL4490-1000-PRO ONLY).

To configure these units, the following are required:

▪Two (or more) CL4490-1000-xxx units (for demonstration purposes, we worked with the RS232 variant)

▪RSxxx-to-USB interface adapters (to enable connection to PC) –not included with CL4490 units

–RS232-to-USB

(examples: FTDI RS232-to-USB Model: UC232R-10, Tripp-Lite Keyspan RS232-to-USB Model: USA-19HS)

–RS485-to-USB

(example: ULinx RS485-to-USB Model 485USBTB-2W

–RS485-to-RS232 combined with RS232-to-USB adapter

(example: B&B Electronics Model: 485SD9TB)

▪PC Operating Windows XP or newer

▪Laird Configuration and Test Utility Software v6.07 from CL4490 Product Page

▪(Optional) Female-to-female pin jumper wire (to tie TX/RX RS232 pins for loopback test) or serial loopback plug

(example: SeaLevel DB9 Female Serial Loopback Adapter)

You will need to download the Laird Configuration and Test Utility Software v6.07 from the CL4490 Product Page.

Note: Downloading the configuration utility will require the completion of a Software Request Form, which will pop up when

you click on the download link. This Software Request Form is required so that we have valid contact information to

use for product update notifications, such as new software releases. Once you submit this form a download link

should be made available at the top of the Product Page. Additionally, you should receive a download link via email.

To install the CU, follow these steps:

1. Once the files have been downloaded, extract them (right-click on file and select Extract All).

The CL4490-1000-PRO radios have DIP switches on the side of the radio, near the antenna and LEDs as shown below, which

enable you to select the Serial Interface, Termination Settings, and TX/RX Mode of the radio. These settings override any

EEPROM configurations, and so must be configured correctly to operate as expected with the settings that will be configured

on the radio with the Laird Configuration and Test Utility software.

In order to configure the radios so they can be connected via the RS232 Interface to a PC, to enable configuration with the

Laird Configuration and Test Utility software follow these steps:

1. On 1st radio configure the DIP switches, as per the diagram on the bottom of the CL4490-1000-Pro unit for Serial

Interface: RS232, Termination: None, TX/RX Mode: Client Addressed

Figure 7: DIP Switch Config Diagram –Client

2. On the 2nd Radio, configure the DIP switches, near the antenna, as per the diagram on the bottom of the CL4490-1000-

Pro unit for Serial Interface: RS232, Termination: None, TX/RX Mode: Server/Broadcast.

Figure 9: DIP Switch Config Diagram –Server

Figure 10: Server DIP Switch Settings

3. After the radios have been configured with the Configuration Software, the selections for pins 1-2, and 3-4 can be set

as per the requirements for the host equipment that the radio will be interfacing with.

Note: RS232 Forced 9600 is for recovery mode ONLY. It should never be used in an application. If a baud rate of

9600 is required, it should be configured using the Laird Configuration and Test Utility.

Warning:Operating the CL4490 Unit without the Antenna attached can damage the radio and void warranty!

To connect the CL4490 to your PC, follow these steps:

1. Attach the antenna to the CL4490.

2. Connect the CL4490 unit to your PC. Depending which variant of the CL4490 is being used, you must connect to your

PC using one of the following setups:

a. CL4490-1000-232/CL4490-1000-PRO can be directly connected to a DB9 serial port on PC using the serial cable

included with the unit.

b. CL4490-1000-232 can be connected using RS232-to-USB serial cable to PC.

c. CL4490-1000-485 can be connected using an RS485-to-USB adapter or combination RS485-to-RS232 + RS232-

to-USB adapter, as shown in Figures 7 & 8 below.

3. Connect the power adapter to power on the radio and verify LEDs as shown in the following Figure 10:

▪Client radio - Green Power LED (Red Link LED shows only when in range of paired server)

▪Server radio –Green Power LED & Red Link LED

Figure 14: Client LEDs (not paired) Server LEDs (or client in range of paired server)

To verify the COM port in the Device Manager, follow these steps:

1. Open Device Manager on your PC.

2. Verify the COM port is properly installed and available. If any issues are indicated on the COM port, verify that the

correct drivers are properly installed for the serial adapter used.

Note: The assigned COM port should be less than 16 otherwise it will not register in the CU.

To configure PC settings, follow these steps:

1. Open the Configuration and Test Utility (CU).

2. Click on the PC Settings tab to configure the following PC settings to enable you to communicate with the ConnexLink

Unit as shown in Figure 4.

a. If Select the product from the Product

drop-down menu.

b. Select the COM Port verified in

Device Manager from the drop-down

menu. If none are listed, click the

[Find Ports] button

c. Default baud rate of 57600 should be

selected, but if it is known that the

unit has been configured to a

different baud rate, select it here.

Note: If connecting to a previously

configured radio, set baud rate

to what is configured on the

radio.

d. Set Parity to None (recommended)

e. Set Handshaking to the following –

depending on the interface:

RS232: Hardware (recommended)

RS485: None

f. Set Data Bits to 8

g. Set Stop Bits to 1

Note: If you receive a message that the read was not successful or Unable to enter command mode, verify the Baud setting

on PC settings tab. You can use AutoBaud mode when prompted to see if the utility can connect with a different Baud

setting. If still having issues we recommend referencing the Troubleshooting Appendix on page 14 of the CL4490 User

Guide. It may be necessary to recover communication with the radio by enabling Force 9600 as per the Application

By default, single units are configured as a client. Each CL4490 system requires one unit to be configured as a server.

1. Configure the client with the following basic settings:

a. Set client/server to Client

b. Set RF Channel –16 by default (must be set the same on server)

c. Set System ID –1 by default (must be set the same on server)

d. Ensure Auto-Destination is enabled

e. Ensure Broadcast Mode is disabled

f. Interface Baud –should be set to host device requirements (for demo we set to 9600)

g. All other settings –Leave as default
