10. Replace the cover and screws. 11. Connect an IBM KEYBOARD to the KEYBOARD connector. Make sure that the keyboard is a type which is compatible with an IBM PC (not AT). 12. Re-connect power to the unit. Press the CTRL, ALT, and DEL keys on the IBM KEYBOARD simultaneously. This will reset the unit, and normal operation will begin. Figure 17 Top of Board Inside the T-60 Changing the Battery in a T-60 Changing ROMS in the T-60 Changing the Battery in a T-60 Follow these steps to change the battery for the non-volatile RAM in a T-60: 1. Save the contents of the program memory. Use a PC and the ApplicationBuilder program to do this. Changing the battery may reset the system if you wait too long to change it or don’t change it quickly, thereby erasing the contents of all memory. 2. Remove power connections to the unit. Disconnect power from the T-60 before attempting to change the battery. Hazardous voltages exist inside the unit with power connected. Personal injury or death may result if the power is not disconnected. 3. Carefully unscrew the top two screws and each of the screws on the side of the unit. 4. Lay the unit face down on a soft, clean surface. 5. Remove the rear cover by carefully lifting it off the unit. 6. Position the cover to the side of the unit, being careful not to stress the internal cables. 7. To remove the old battery, insert a small screwdriver between the edge of the battery and the battery holder near the battery clip (see diagram). Push gently and the battery should slide out. Figure 18 Battery Replacement 8. Before installing the new battery, press down on the battery clip to make sure that there will be good retention force when the battery is in place. Also make sure that all contact surfaces are clean. As noted on the battery clip, make sure that the positive (+) side of the battery is up. Slide the battery under the clip and into the battery holder. Make sure that the battery is held firmly in place. Improper orientation of the battery will not allow the battery backed RAM to function and your memory will cease to be non-volatile. However, this will not damage the battery or the controller; just turn the battery over and continue with the installation procedure. T-60 Operator's Manual 9. Replace cover and cover screws. 10. Reconnect power to the unit. 11. If you notice any problems that can’t be explained by the battery being installed upside down (no non-volatile memory), disconnect power and connect an IBM KEYBOARD to the KEYBOARD connector. Make sure that the keyboard is a type which is compatible with an IBM PC XT (not AT). 12. Re-connect power to the unit. Press the CTRL, ALT, and DEL keys on the IBM KEYBOARD simultaneously. This will reset the unit, and normal operation will begin. Call Emerson EMC if any problems persist. Real Time Clock Adding the Real -Time Clock to the T-60 Real Time Clock The CLK option adds a battery backed real time clock to the T-60. Once installed you can set the date, day of the week and time with a single statement: CALL WRCLOCK. You can read the day, day of the week, and the time with another single statement: CALL RDCLOCK. Refer to the EMERSON EMC BASIC USERS GUIDE for the programming syntax for these new commands. The CLK option’s battery is integrated into a removable module which has a sealed internal lithium battery which is designed to last 10 years. The CLK option is field installable. Adding the Real -Time Clock to the T-60 Follow these steps to add a real-time clock (CLK option) to the T-60: 1. Save the contents of the program memory. Use a PC and the ApplicationBuilder program to do this. 2. Remove power connections to the unit. Disconnect power from the T-60 before attempting to install a CLK Option. 3. Carefully unscrew the top screws and each of the screws on the side of the unit. 4. Lay the unit on its back on a soft, clean surface. 5. Remove the front panel by carefully lifting it off the unit and disconnecting the 2 pin connector for the backlight cable (J6, see diagram). 6. Position the cover to the side of the unit, being careful not to stress the internal cables. 7. Insert the CLK option in socket U7. Be sure that PIN 1 (location on the CLK with notch or dot) is facing down (towards the center of the unit, see diagram). Check carefully for bent or damaged pins. Improper orientation of the CLK will destroy it, and possibly cause damage to the unit. Figure 19 Top of Board Inside the T-60 T-60 Operator's Manual 8. Reconnect the backlight cable connector and replace the front panel and screws. 9. It may be necessary to set the real-time clock before it can be used. Refer to the BASIC User’s Manual for instructions on how to set the clock. Event Driven Software Adding the Real -Time Clock to the T-60 Event Driven Software The EMERSON EMC T-60 Event Driven Software allows the T-60 to react quickly to external events, without taxing the overhead of the imbedded BASIC programming language. The Event Software allows the T-60 to scan ...
