Throughout this chapter of the manual, the following symbols and
conventions will be used to clarify what type of data we are addressing.
• Items enclosed in {brackets} will denote one byte.

character. A byte described in ALL CAPS is the ASCII description
of a non-printable character. The abbreviation dec will denote a
decimal value. The lower case letter h will be used to show a Hex

LED Indicators
The 232BSS4 has five LED indicators. The first, labeled “+12 VDC
POWER” indicates that power is applied to the switch. The other four,
labeled “PORT A” to “PORT D” indicate which Slave port is currently
selected to transmit to the Master.
In Smart Switch Only mode, the port LEDs indicate which port was
selected through the Select Port command. In Auto Select mode, the port
LEDs indicate which port is currently sending to the Master. No indication
is provided to display which Slave port is currently receiving from the
Master.
