OP, wake-up sequence
Serial data can be transmitted to a recording device automatically without a request. However,
many devices demand a wake-up sequence before they can receive and process data. The SPA-2
has the option to send a sync sequence and a prefix before data are transmitted (see
). The following options are available:
Option
Description
off
No wake-up sequence
sync

prefix
(default)
A blank with a time delay is sent before the output string.
prefix & sync
A blank with a time delay and the sync sequence UU~?~? is sent before the out-
put string.
