Connecting Serial Devices

This section discusses connecting your serial devices. In addition, it provides you

with information to build serial or test cables and loopback connectors to test the

serial ports.

Use this procedure to connect asynchronous serial devices to the DeviceMaster

AIR 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 peripheral for the

wrong mode could damage the peripheral.

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

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

Serial Cables and Loopback Plugs

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

need help with connector pinouts or cabling for the peripheral device.

2. Verify that the devices are communicating properly.
