Remote Operation
RS-232 Control
The SWP123 RS-232/RS-422/RS-485 serial control port accepts serial commands from a control
system, computer serial port, or any other device capable of sending out serial ASCII commands
at compatible baud rates. A complete listing of RS-232/RS-422/RS-485 codes is included below.
Communication Protocol:
• 8 data bits
• 1 stop bit
• No parity check
• 9600 baud (factory default setting)
• Full duplex
Protocol Structure
All commands sent to the unit must contain a leading character, the actual command, and an
ending character. The SWP123 can accept multiple commands, storing them in a buffer. It
immediately executes each command in the order it was issued.
The SWP123 recognizes [ and ] as leading and ending characters, also called Command Codes.
The factory default for the Command Code is [ ]. Some sample command codes follow. For
example:
This part of the command string... Represents:
[
ARC
]
This command string... Means:
[ARC]
The leading character
The actual command.
The ending character

Serial Commands
Addressing Commands
If the switcher is being used in RS-232 mode (no other devices connected in parallel) there is no
need to assign an address for this unit. If you are using multiple Inline products connected in
parallel to a single serial port using RS-422 or RS-485 communications, you will need to assign
an address for each unit.
The factory default for the unit is no address. The address for the unit must be between 01 and
98. Address 00 is a broadcast address and all units on the buss will perform the action
commanded; however, they will not issue any responses.
To open communications to an addressed device, you must send a [CCxx] command. All other
devices on the buss will ignore commands until addressed.
COMMAND DESCRIPTION
[ADDRxx] Assigns an address to the unit, 01 to 98. Address 99 is reserved.\
• xx = 01 - 98
[ADDR@]
[ADDR?]
[CCxx] Connects controller to the addressed unit. 00 is a broadcast address thus
Set-up Commands
These commands are for configuring the switcher, and you only need to send them once. If using
a third-party control system, you should place most commands in this section in the start-up
section of the program.
