SIS Programmer’s Guide
4-2
The USP 507 can be operated and configured using Simple Instruction Set
™
(SIS
™
)
commands input via a PC connected to the top RS-232 port on the rear panel or the
Ethernet port. See m on page 2-4, and Appendix B for wiring details.
RS-232/RS-422 Link
The USP 507 has one rear port (the upper serial port) and one front port (see a on
page 3-2) that can be used for serial control. All ports enable use of SIS commands
and the Windows
®
-based control software. The default protocol for these ports is:
• 9600 baud, • 1 stop bit, • no parity, • no flow control, • 8-bit.
N
The lower rear serial port (named Aux SW Follow) is for connection to an
auxiliary device and should not be connected to a PC or control device.
Ethernet (LAN) Port
The rear panel Ethernet connector on the unit can be connected to an Ethernet
LAN or WAN. Communications between the unit and the controlling device is via
Telnet (a TCP socket using port 23). The TCP port can be changed if necessary. This
connection makes SIS control of the unit possible using a computer connected to
the same LAN or WAN. The SIS commands and behavior of the unit are identical
to that when communicating to it via RS-232.
Ethernet connection
The Ethernet cable can be terminated as a straight-through cable or a crossover
cable and must be properly terminated for your application. See Appendix B for
cable termination details.
Default IP addresses
To access the USP 507 via the Ethernet port, you need the Extron IP address and
may need the subnet mask and the gateway address. If the IP address has been
changed to an address comprised of words and characters, the actual numeric IP
address can be determined using the ping (ICMP) utility (see Appendix B for more
details). If the addresses have not been changed, the factory-specified defaults are:
IP address: 192.168.254.254, subnet mask: 255.255.0.0, gateway address: 0.0.0.0.
Establishing a connection
Establish a network connection to the processor as follows:
1
. Open a TCP socket to port 23 using the processor’s IP address.
N
If the local system administrators have not changed the value, the
factory-specified default, 192.168.254.254, is the correct value for this field.
The processor responds with a copyright message including the date, the
name of the product, firmware version, part number, and the current
date/time.
N
If the processor is not password-protected, the device is ready to accept SIS
commands immediately after it sends the copyright message.
If the processor is password-protected, a password prompt appears below the
copyright message.
2. If the processor is password protected, enter the appropriate administrator or
user password.
If the password is accepted, the processor responds with Login User or
Login Administrator.
If the password is not accepted, the Password prompt reappears.
