and the hub will add an address character so that you know which drive the response came from. A typical
response might be “2IS=00000000”.
To send a command to all the drives that are connected to the hub, just omit the address (for example: FL).
The following SCL commands can also be used to control or query the hub itself. Address “0” is always used
for commands that affect the hub.
0BR - This sets the bit rate of all the serial ports in the hub. 0BR1 specifies 9600 bits/second. 0BR2
indicates 19200 bps. The power up bit rate is 9600. You must do this in the correct sequence or communi-
cation will be lost. Think of your system as a pyramid: the PC is at the top. The next layer is the hub and
the base of the pyramid cosists of the drives that are connected to the hub. Always start at the bottom. For
example:
a) Make sure that all the drives in your system have firmware version 2.10 or later. The “RV” command will
report the firmware of all drives connected to the hub.
b) Send the command 1BR2. This asks drive 1 to change to 19200 bps.
c) Repeat step (b) for each drive (2BR2, 3BR2, etc)
d) Change the bit rate of the hub by sending 0BR2
e) Change the bit rate of the PC. If you are trying this with the
SCL Setup Utility, which we highly recom-
mend, there is a drop down list for setting the PC bit rate.
Don’t forget: at power down, the drive and hub change back to 9600 bps. If you send the hub the command
“0BR” with no parameter, the hub will report its present bit rate, for example “0BR=1”.
Requires Hub firmware version 1.14 or later, and drive firmware 2.10 or later.
0IH (Hub444 only) - Sets one of the Hub’s four on-board outputs high (open) immediately. Your must
specify which of the four outputs you want to use: 0IH1, 0IH2, 0IH3 or 0IH4.
0IL (Hub444 only) - Sets one of the Hub’s four on-board outputs low (closed) immediately. Your must
specify which of the four outputs you want to use: 0IL1, 0IL2, 0IL3 or 0IL4.
0IS (Hub444 only) - requests the input status of the hub’s four inputs. Responds in the same format as a
drive IS command. This is an immediate command.
0PM - sets the hub’s power up mode. 0PM1 sets the hub for autodetect mode, where it can be used as an
SCL Router or with the SiNet Hub Programmer software. A command button in the
SCL Setup Utility can
also be used to set the power up mode.
0RV - makes the hub report its firmware version.
0SO (Hub444 only) - sets one of the hub’s four on-board outputs to a specified state (high or low). To set
output 3 low, use the command “0SO3L”.
