Control Pearl-2 with RS-232
You can use the null-modem cable and your control terminal software to issue commands to Pearl-2, such as
when to start or stop recording, and to retrieve or set the value of certain parameters.
Each command sent to Pearl-2 over RS 232 must be terminated with a line feed(LF) character
(ASCIIcode 10). Make sure that your software adds the line feed to each command.
Some commands require a channel or recorder name as an argument. In those commands, the channel or
recorder name is separated from the command name by a period. The channel name value can be either the
name or the index of the recorder or channel. Use of the index is recommended.
A channel's index number is located in the Channels Menu using the Admin panel. The channel index number
turns red to indicate it is recording. For example, to address this channel using RS-232 commands, use the
index 1.
For recorders, combine the recorder's number with the prefix m. In the following example, the second
recorder's index is 2. To address this recorder using RS-232 commands, use the index m2.
