An obvious precaution in the above procedure after loading the WORKING register with the current MSM400 control unit data, is to transfer this data to the SAFE register in case the OFF-LINE sorted new programme does not give the expected result – if necessary the MSM400 can be restored to its original programme status by transferring the SAFE register data to the WORKING register.

The OFF-LINE register is retained when the communicator is disconnected from the loop or powered down. It is only wiped when a new set of data is transferred to the OFF-LINE register from the WORKING register.

Only one set of parameters can be stored in the OFF-LINE register at once.

DEFAULT REGISTER

This is the register of all the normal ex factory settings for the MSM400 Control unit. It is a useful start or reference point for programming any control unit, since the values set in each parameter are known and only those that need The screens showing the Transfer functions of data between registers provide step by step instruction for achieving such data transfer . There are also facilities for allowing the normal interface between the Psion Organiser and a printer or personal computer to provide output of the MSM400 programme data.

The options presented on the LCD are amended when the SMART Communicator senses that a loop

is not present or the Interface unit is not plugged into the Psion. In such cases OFF-LINE operation is offered or selected automatically. After changes to the PROGRAM screens which modify data in the WORKING Register, these changes must be saved in the OFF-LINE Register or to a Data File using the TRANSFER function.

The BACK-UP selection on the main FUNCTION menu allows manipulation of the data held in the various registers. Since all transfers are to or from the WORKING Register, the initial screen

Immediately transfers data to the WORKING Register if SAFE or OFFLINE are selected. If the source is a Data File then a location and a File name are prompted for and the data is transferred to the OFFLINE Register followed by a transfer from OFFLINE to WORKING. This final transfer can be prevented by pressing “N” when asked to accept that the output may be changed. If the data source is the WORKING Register, the screen prompts for a full upload if any parameters have not yet been read then asks for a destination decision.

The location is either the internal memory at A or a Data or Rampak in the upper side slot which is B. The filename can be up to 8 characters long. In this case the WORKING Register remains unchanged after the data transfer.

Please note that Parameters in the range P44 to P69 are not transferred to the WORKING Register in any BACK-UP data transfer. These parameters are left as set up by the Service Engineer for that particular control unit.
