Lan/Serial-Port Commands - Black Box 2 x 2 SCSI Matrix Switch SC121A User Manual

5.6 LAN/Serial-Port Commands

You can use simple ASCII-character commands to control the SCSI Switch through
either its LAN port (by opening a socket connection to port 3001) or one of its
RS-232 serial ports. For serial control, set your computer's serial port this way:
a. Baud rate: 9600 (the switch's factory default) or 19,200 bps.
b. Data format: 8 data bits, 1 stop bit, no parity.
c. Transmission mode: Half-duplex.
So, for example, the DOS command to set a PC for serial communication with the
switch would be MODE COMx 9600,N,8,1. Whether you're using a LAN or serial
connection, commands have the same syntax (format):
a. Start sequence: ASCII <cr> (carriage return) followed by two slashes ("//")
b. Switch box number (you need this even if you have only one SCSI Switch):
Box 1 - 7C hex (ASCII "|")
Box 2 - 7D hex (ASCII "}")
c. Port selection:
Port A to port 1: "A1", port A to port 2: "A2";
Port B to port 1: "B1", port B to port 2: "B2"
1. More than one port connection can be selected at the same time. For
example, to select A1B2, transmit "A1B2."
2. "0" clears (disconnects) all numbered ports. For example, "A0" clears
any numbered port connected to port A.
d. Connection or disconnection type:
ASCII "K" connects the specified ports and strictly adheres to SCSI rules.
With "K," if port A or B is not specified, no action will be taken on that
port. If a connection is selected (for example, "A1"), that connection will
be made, and the other numbered port will be disconnected from that
lettered port. For example, entering "A2K" when port A is connected to
port 1 will disconnect port A from port 1 and connect it to port 2.
ASCII "N" connects the specified ports without breaking existing connections.
ASCII "F" disconnects the specified ports.
e. End sequence: ASCII <cr>
So, for example, the complete command to connect the first SCSI Switch's port A
to port 2 and its port B to port 1 would look like this: <cr>//|A2B1K<cr>
