MZ-805 L/C/R meter

8 REMOTE OPERATION

General
The instrument can be remotely controlled via its RS232 interface.
At power-on the instrument will be in the local state with the REMote
indicator off. When a command is received the remote state will be entered and
the REMote indicator will be turned on. The keyboard is not locked out and the
instrument may be returned to the local state by pressing any key; however, the
effect of this action will only remain until the instrument receives another
character from the interface, when the remote state will once again be entered.
Remote command format and the remote commands themselves are
detailed in the Remote Commands chapter.
RS232 Connector
The 9-way D-type serial interface connector is located on the instrument
rear panel. The pin connections are as shown below:

used.
