5 Specifications
5.a System monitor
The system monitor is designed to monitor the health and status of the chassis system. It communicates to a host via a
100Base-T Ethernet connection. It monitors 4 fan tachs, 8 temperature sensors and 3 voltages. All configuration
parameters are stored in non-volatile FLASH. All control and monitoring signals are routed via a single 40 pin connector to
the backplane where the I/O signals are efficiently routed to their corresponding functions. The ethernet signals are
connected through a RJ-45 connector. Refer to Appendix A: System Monitor GUI for a complete software interface.
The system monitor is tested for compatibility with:
o Monitors 8 temperatures
o Monitors 4 fan tachometers
o Monitors 3 voltages
• Communications to a host via an Ethernet
(TCP/IP, TelNet, and UDP) or I
2
C connection.
• Configuration parameters stored in non-volatile

• Stored in non-volatile memory and retained without power
Power consumption
• 237mA at 5V = 1.2 watts (the board runs on 5V only)
• Can be quickly and easily changed
• Dip switch settings allow network configuration to restore to default settings
Mechanical
• 4” (9cm)L x 3” (7.6cm)W
• 0.76” (1.9cm) stack height with passive heat sink
Operating environment
• Temperature range:
o Operating: 40°—85°C
o Storage: -40°—85°C
• Humidity range:
o Operating: 10% to 90% relative (non-condensing)
o Non-operating: 5% to 95% relative (non-condensing)
+5V (AUX) is automatically enabled after AC power is applied and is used to power all circuitry on the system monitor.
System monitor power-on sequence less than 1 second.
The system monitor will then monitor all 8 temperature sensors.
Network configuration
You must configure the system monitor so that it can communicate on a network. The unit’s configuration is stored in
nonvolatile memory and is retained without power. The network configuration can be changed at any time. The
Ethernet Controller performs a reset after you change and store the configuration.
DHCP
The unit ships with a default IP address of 192.168.1.99, which automatically enables DHCP. If a DHCP server exists
on the network, it will provide the unit with an IP address, gateway address, and subnet mask when the unit boots up.
IP address
The IP address must be set to a unique value in your network.
Set gateway IP address
The gateway address, or router, allows communication to other LAN segments. The gateway address should be the IP
address of the router connected to the same LAN segment as the unit. The gateway address must be within the local
network. The default is the gateway address has not been set.

Netmask: number of bits for host part
A netmask defines the number of bits taken from the IP address that are assigned for the host section.
NOTE: Class A: 24 bits; Class B: 16 bits; Class C: 8 bits.
Port number
The setting represents the source port number in TCP connections. It is the number that identifies the channel for
remote initiating connections. The default setting for Port 1 is 10001. The range is 1-65535, except for the following
reserved port numbers:
The port number functions as the TCP/UDP source port number for outgoing packets. Packets sent to the unit with this
port number are received to this channel. The port number selected is the Incoming TCP/UDP port and Outgoing
TCP/UDP source port. Use Port 0 when you want the outgoing source port to change with each connection. If the port
number is 0, the initial value of 5000 actively establishes a connection. Each subsequent connection increments the
number by 1. When the port number reaches 7999, it wraps around to 5000. Only use the automatic port increment
feature to initiate a connection using TCP. Set the port to a non-zero value when the unit is in a passive mode or when
you are using UDP instead of TCP. Although the System Monitor allows multiple clients to access the System Monitor
with the auto-incrementing Port number feature, undetermined results may occur if more than one user issues
commands or data simultaneously. Therefore, single client connection is recommended unless all clients can
guarantee completion of the current command and data transfer
before issuing another command.
Recovery mode
The system monitor provides a dip switch setting that allows the
Network configuration parameters to restore to their default settings.
This guarantees that communication with the System Monitor can be
reestablished in the event that the network settings are forgotten or
somehow set to unknown values as the result of communication or
software error. The Dip Switch is read only at power-up.

A.4 Troubleshooting
The Myclient.exe visual basic program requires the MSWINSCK.OCX file. If your computer does not have this file or
the program does not work correctly, then follow the tasks listed below:
1. Back up your current copy of MSWINSCK.OCX if there is one present. Copy the new version to the same
location. See below for correct directory:
• For Windows 95, 98, or Me, the MSWINSCK.OCX file should be located in the WINDOWS\SYSTEM directory
on your C: drive (for Windows NT and 2000: \WINNT\system32).
• For Windows XP, NT or 2000, the MSWINSCK.OCX file should be located in the WINDOWS\SYSTEM32
directory on your C: drive
2. Using your mouse, click on the "Start" button and then click on "Run".
3. According to your Operating System, type the following command to register this library file:
• Windows 95, 98, or Me: regsvr32 \windows\system\MSWINSCK.OCX
• Windows NT or 2000: regsvr32 \WINNT\system32\MSWINSCK.OCX
• Windows XP: regsvr32 \windows\system32\MSWINSCK.OCX
4. You should see a message saying "DllRegisterServer ... succeeded"

Appendix B: System Monitor Command
Protocol
The following section describes the basic command protocol to communicate with the System Monitor to retrieve
sensor data, configure, and control various I/O. All commands are sent via Ethernet through TCP/IP or Telnet
protocols. All commands sent to the System Monitor will be acknowledged by System Monitor returning the value
0xAC. Some commands require the System Monitor to update internal Flash that can take up to 20msec, therefore,
the application should not send additional commands until it has received the ACK (0xAC) from the System Monitor.
Any user timeout functionality should delay for 250msec worst case before retrying to communicate with the System
Monitor.
The sensors monitored are +12Volt, +5Volt, +3.3Volt, -12Volt, 8 Fan Tachs, 6 Temperature sensors, and 4 digital
Inputs. All sensors are configurable to enable sensor, enable alarm condition, and set type of alarm condition to Minor,
Major, or Critical. The Voltages, Temperature sensors, and Fan tach are configurable for a high and low threshold to
indicate an alarm condition. The Digital Inputs polarity are configurable to indicate an alarm condition for a high input
or low input.

The GET_SYSMON_STATUS command provides a global status of all alarm conditions with a single byte of data.
The GET_ALL_SENSOR_STATUS command allows all sensors to be monitored for alarm conditions with 4 bytes of
data.
The GET_ALL_SENSOR_DATA command provides all sensor data including alarm condition and type of alarm.
The GET_SENSOR_DATA command allows the user to monitor specific sensors.
The CONFIGURE_SENSOR command sets configurable sensor parameters such as enabling the sensor, enabling
alarm, setting the type of alarm (minor, major, or critical), setting the high and low thresholds for alarm conditions,
setting the polarity for the GP_Inputs, and setting the Fan Tach/Revolution divisor.
The WRITE_OUTPUT_REGISTER command allows the user to set General Purpose outputs to a TTL high or low
level.
The READ_OUTPUT_REGISTER command reads the value written to the WRITE_OUTPUT_REGISTER.
The SET_IP_ADDRESS command sets the IP Address of the SYSMON. Setting the IP Address to 0.0.0.0 will enable
DHCP.
The SET_IP_SUBNETMASK command sets the SUB NETMASK of the IP Address.
