Serial Transmissions
The length of the value of all serial signals (all the
Set—
signals) is limited to 83
characters. Furthermore, the total length of all signals (including header bytes) to be
transmitted in a single logic “wave” must not exceed 255 characters. If the total
length of all signals required to specify the strings for an e-Mail message exceeds
255 characters, you must ensure that transmission occurs in several waves (by
installing sufficient delays between signals).
Signal Definitions
The XSIG format limits the number of signals to 4096, only the first 1024 of which
may be analog or serial signals. Furthermore, the older generation of Crestron
control systems has a limit of 512 analog/serial signals. (This is not an issue with the
newer CNMSX and CNRACKX systems which allow a full 4096 analog/serial
signals.)
