7.5.1.2 Remote Control Enable SW1-3
This switch enables remote control via RS-232 and the external serial port. The default is
Enabled; setting to Disabled does not change operation in any way except incoming RS-232
commands will be ignored.

7.5.1.3 Serial Sync Character SW1-4
This switch adds the requirement that all remote control commands are preceded by the
synchronizing character ^ (ASCII character 0x5E). The default setting is OFF, as this is not
normally required. The sync character may improve remote control operation under
electrically “noisy” conditions, such as the presence of high levels of RF energy.
