SYNCHRONISERS, DELAYS & SILENCE DETECTORS - RB-DS2
7
Serial Port Control
The Serial Port allows the RB-DS2 to be controlled and updated from a PC via a pin-to-
pin serial cable, using the Sonifex Serial Control Interface (SCI) software. This software is
available as a free download from the Sonifex website at www.sonifex.co.uk/sci.
Default Settings for the Serial Port
Baud Rate: 19200
Data Bits: 8
Stop Bits: 1
Parity: Even
Handshaking: None
Serial Interface Commands and Responses
Most of the commands follow the same structure: a 3 letter command followed by a colon,
followed by a parameter (if any) and terminated by Carriage Return with optional Line Feed.
A Line Feed character may be sent but it will be ignored by the RB-DS2. Commands are not
case sensitive.
Responses will be CR & LF terminated.
After the delay synchroniser has been powered-up, an initialisation string is sent
“Initialising DS2”.
Following are the commands and the expected responses:
Command Description Response
Bnn: **Set baud rate where ACK: or NAK: (at old rate)
nn = 11 (115200 baud)
nn = 57 (57600 baud)
nn = 38 (38400 baud)
nn = 19 (19200 baud)
nn = 96 (9600 baud)
BPD: Bypass disable ACK: or NAK:
BPE: Bypass enable ACK: or NAK:
BSV: **Bootstrap version request where BSV:Vn.n
n.n = bootstrap version
