Serial Ports
The FOX DA8 has two serial ports that can be connected to a host device such as a
computer running the HyperTerminal utility, an RS-232 capable PDA, or a control system.
These ports make serial control of the DA8 possible. The serial ports are:
z The rear panel RS-232 port on a 3-pin captive screw connector
z The front panel CONFIG (RS-232) port on a 2.5 mm mini stereo jack
Simple Instruction Set ™ Control
Host-to-interface Communications
The Extron Simple Instruction Set (SIS) commands consist of one or more characters per
field. No special characters are required to begin or end a command character sequence.
When a command is valid, the unit executes the command and sends a response to the host
device. All responses from the unit to the host end with a carriage return and a line feed
(CR/LF = ]), which signals the end of the response character string. A string is one or more
characters.
Start-up Message
When a local event, such as a front panel operation or error condition, occurs, the unit
responds by sending a message to the host. The unit-initiated messages are listed below:
(c) COPYRIGHT 2009, EXTRON ELECTRONICS FOX 4G DA8,
Vx.xx, 60-927-xx ]]
The FOX DA8 issues the copyright message when it first powers on. Vx.xx is the firmware
version number, 60-927-xx is the part number.
Error Responses
When the unit receives a valid SIS command, it executes the command and sends a response
to the host device. If the unit is unable to execute the command because the command is
invalid or it contains invalid parameters, the unit returns an error response to the host. The
error response codes are:
E10 — Invalid command ]
E12 — Invalid output number ]
E13 — Invalid range ]
