Operation

Introduction

The TnT Memory model has inbuilt flash memory and real time clock. This gives the ability to store up to 5000 records, which can include items from 16 different sites and 6 different users. This will help to increase the efficiency and pace of testing. The TnT memory unit has two operating modes:

Standard TnT tester (Non-memory)
Test and Tag (memory)

The TnT mode is determined if a keyboard is connected. If there is no keypad detected then the TnT will load the main menu screen and function as a standard unit. If the keypad is present then the new barcode screen will be loaded.

Switching on the Tester

When the tester is powered the scanner will beep a few times indicating the scanner is also powered. If no beep is heard check the PS2 connections from the tester.

If the TnT tester gets stuck on the logo screen please check the connectivity of the keypad / scanner cable. The TnT unit will not work if only the scanner is plugged in. If you are using the scanner you need the keypad plugged in as well. Not having a scanner and just the keypad works too.

Initially the printers status light will be orange but after about 5-10 seconds it will change to green. The tester will not print unless the printer light is solid green. A flashing red status light can indicate a media or general printer fault.

Adding New Equipment

The following must be done before testing:

Create a site or use and existing site.
Create a user name to under the users list.
If auto generate number is used the initial number must be set correctly.
If you are adding equipment to an existing site please make sure that the correct site is displayed. If the wrong site is displayed the equipment will be assigned to the wrong site.

When the testers memory has been erased it will look like the following screen.
