Table 8.2 Addition Message
Mnemonic Description Format
RMT Remote changeover
request
[Format]
RMT
When controlling by the RS-232 interface, the DSM-8542 changes to a remote state
when the RMT command is received, allowing control by RS-232. In the beginning,
send this command.
Press the [LOCAL] key to reset to a local state from a remote state.
Table 8.3 Invalid Messages
Mnemonic Description
*OPC OPC bit setting when processing ends
*OPC? “1” is returned when operation completes
Sending a command message requesting a response in RS-232, a response is received
first and next command message can then be received. For this reason, commands for
checking operation completion become invalid. (Actually such commands are accepted,
but there is no reason to use them)
Caution for use of RBF? command
Use “RBF? 0” as the data buffer readout command. The format will still be the ASCII
format even if “RBF? 1” is specified.
Delimiter during reception
Use “C
R
L
F
” as the delimiter when sending a command message.
8.7 Status Byte and Events
The following events differ from the GP-IB interface and will become invalid:
Bit 3 of the Status Byte register (MAV)
Bit 2 of the Standard Event Status register (QYE)
