Remote, RS 232 interface, data backup

General

Data backup should be performed prior to new installations and programming modifications of the DMM 4650. This ensures that replacing an appliance for service purposes takes the least effort, immediately providing identical functions on the replacement unit. When setting-up systems with similar functions more often, the programming data can be copied using a ready-made data carrier.

For data backup a PC with serial interface and a terminal program is necessary. Please note that the guidelines of the manufacturer of data media (disks, tapes etc.) are to be observed for maximum data safety, since they guarantee data integrity for a limited period of time only.

Using a medium transfer baud rate, the backup of a device status including its gong, alarm, sequences and trigger (“backup”) presets lasts about 10 seconds. If the audio data of the message memory(“backup message”) is supposed to be saved additionally, the duration depends on the length of the recorded messages and can last several minutes (short message) up to some hours (memory completely used). Thus, it is recommended to perform an audio data backup via the menu “message edit Play all” onto a DAT recorder or tape deck.

Backup, Restore commands, Priority

The “backup” command can be given both, from the DMM 4650 menu“System setup > backup”, as well as via the REMOTE interface. After starting the backup procedure, the desired data is transmitted in the previously determined format via the REMOTE interface. The PC’s terminal program receives the data and creates a corresponding file. The terminal program’s configuration is not to be set for any conversion of the received data.

Part of backup file:

RESTORE A00: data

RESTORE G00: data

RESTORE s20: data RESTORE TA.1: RESTORE U: data

RESTORE is needed for data re-storing, A00 = alarm preset 00, G=gong, S=sequences, s=stop trigger, TA.1 =trigger PortA Input1, M=message and U=basic settings. This text file can be altered using an editor, e.g. by altering A00 into A05 or deleting whole presets including all data belonging to them. :Data consist of the character string which belongs to the preset and which may not be altered. (! word processor software like WORD or Word Pad should not be used to perform the described alterations, since they add they own format strings to the text.)
