In the image below, this phrase was typed on the computer keyboard and appears in the terminal window. For the English language, one phrase that includes all of the letters in the alphabet and each number is THE FIVE BOXING WIZARDS JUMPED QUICKLY 1234567890. (For example, if a single “A” is typed, a single “A” should be returned-not a different character or multiples of the letter “A.”) To test this, type each letter and number at least once. Tip: To be functioning correctly, the modem must return ALL letters and numbers correctly. These characters should appear in the terminal window. Use the computer keyboard to type some characters (letters and numbers).

A jumper from the RCV - terminal to the XMT - terminalĪfter the jumpers are in position, connect a serial cable from the COM port on the computer to the short haul modem.A jumper from the RCV + terminal to the XMT + terminal.

#HOW TO USE HYPERTERMINAL INSTALL#

For example, if your wiring looks similar to the image below, you might make a small chart to indicate which wire goes where, like this:Īfter you disconnect the wires from the modem, you can use bent paper clips to install two jumpers: Tip: Before you disconnect your wires from the short haul modem, make a note or take a picture of the connections so that you can easily reconnect the wires when you are finished with your testing. To get started with this test, you will need to label the wires that are connected to your short haul modem and disconnect them. To test the functionality of your modem, whether it’s usually connected to a computer or a data logger, you can perform a loopback test on it.įor many years, Campbell Scientific has sold the RAD-manufactured SRM-5A Short Haul Modem, which is used in the example images for this test. In fact, it’s interesting that the short haul modem connected to the computer is damaged much more frequently than the short haul modem connected to the data logger. Short haul modems are vulnerable to damage from electrical surges that may be caused by lightning or other events. Ensure that the serial cable is connected to the correct port and that no other program is also trying to use the COM port that you’re testing. If you used the short and the characters you typed on your computer keyboard did NOT appear in the terminal window, there is a problem with the computer’s COM port or the cable. If you remove the short (for example, by removing the screwdriver), any characters that you type on the computer keyboard should NOT appear in the terminal window. In the image below, the phrase “THE FIVE BOXING WIZARDS JUMPED QUICKLY 1234567890” was typed on the computer keyboard and appears in the terminal window. Note: The Echo Input checkbox should NOT be checked in the terminal window for this testing. While pins 2 and 3 are shorted, use the computer keyboard to type some characters (letters and numbers). No damage will occur, but the loopback test will not work properly. Tip: Don’t let the screwdriver touch the shell of the cable. In the image below, a 25-pin serial cable is used for the loopback test. You can use something other than a Phillips screwdriver, as long as it is electrically conductive. In the image below, a Phillips screwdriver is used to short pins 2 and 3 on a 9-pin serial cable. Then short pin 2 and pin 3 of the cable together. (In a loopback test, a signal is sent from a device and returned, or looped back, to the device.) For this test, connect a serial cable to the COM port that you want to test. To test if the computer COM port is functioning correctly, you can do a simple loopback test.

DevConfig is a part of all Campbell Scientific data logger support software, and you can download a free, standalone version of DevConfig.

#HOW TO USE HYPERTERMINAL WINDOWS#

There’s an easy-to-use terminal window, compatible with all Windows OSs, in the Device Configuration Utility (DevConfig). So, how do you get one of those? Prior to the release of Windows Vista, you could use HyperTerminal, a terminal emulation program that was included with Windows operating systems (OSs).

To perform these tests, you will need a terminal window.
