DeviceMaster Installation and Configuration Guide: 2000506 Rev. B Connecting Serial Devices - 53

Connecting Serial Devices

This section discusses connecting your serial devices to the DeviceMaster. In addition, it

provides you with information to build serial or test cables and loopback connectors to

test the serial ports.

Note: Go to Building the Serial Ribbon Cable

on Page 16 for connector information for the

DeviceMaster 1-Port Embedded adapter.

Connecting Devices

Use the appropriate procedure to connect asynchronous serial devices to the

DeviceMaster ports.

Make sure that you have configured the ports using the NS-Link driver or

SocketServer for the correct communications mode before connecting any

devices. The default mode in the NS-Link drivers is RS-232. There is a remote

possibility that connecting a serial device for the wrong mode could damage the

serial device.

1. Connect your serial devices to the appropriate serial port on the DeviceMaster using

the appropriate cable. You can build your own DB9 or RJ45 cables using the

appropriate discussion:.

on Page 59

• RJ45 Serial Cables and Loopback Plugs on Page 61

Note: Refer to the hardware manufacturer’s installation documentation if you need

help with connector pinouts or cabling for the serial device.

2. Verify that the devices are communicating properly. Go to the appropriate table for

information about the LEDs, which may provide information about the installation.
