Wireless Networking
SIGMA Manual Number 41019
Revision AA
W IR ELESS NETWORKING
The Sigma Spectrum Infusion Pump offers an optional wireless battery module (SIGMA P/N 35083)
providing an 802.11b wireless networking capability, and an optional wireless battery module
(SIGMA P/N 35162) providing an 802.11b/g wireless networking capability. In conjunction with a
host computer system, the pump Drug Library can be updated to a new library and pump status
information may be sent via a wireless network connection to a host.
The pump includes a number of networking parameters that must be configured for the pump to
access and use the wireless network.
When a new pump is first received from Sigma, the BioMed department must configure each pump’s
network parameters as described below. The BioMed department will need to coordinate with the
facility’s IT department to determine the proper settings for the network parameters.
These network parameters are changeable by sending a configuration file to the pump via an IrDA
interface. The pump can also send its current network configuration file to a PC or PDA via the
IrDA. A PC with an IrDA interface can be used to program multiple pumps with the same configura-
tion. The network configuration file is a simple text file that can easily be edited on a PC and sent via
the IrDA to a pump. After changing the pump’s network configuration, the pump may need to be
power cycled for the net settings to take effect.
Each pump stores its configuration information in non-volatile memory, so that even if it loses all
power sources (AC and battery) its settings are not lost.
The following is a description of the parameters required in order for the wireless interface module
to work properly with the host. These parameters may be accessed and reviewed as previously indi-
cated in the BioMed Options portion of this manual.
Network Configuration
Network Status
This option shows the current status of the network connection. The following items are available:
■
MAC Addr – displays the media access control (MAC) address of the pump. This address is
associated with the wireless battery module connected to the pump.
■
IP Addr – displays the current IP address of the pump.
■
SIGMA GW – displays the IP address or DNS name of the network host, also known as the
SIGMA Gateway server.
■
Network Status – displays the current status of the wireless radio and network connection.
If the wireless radio is connected to a network, the relative receive level will be reported as a
percentage. While the radio is disabled or booting, pump event information is not buffered
or sent to the network host. Network drug library updates are only available when the
pump is connected to a host.
■
Error Message or Network Information – displays status information or error conditions
about any abnormal conditions that may be preventing the pump from accessing or using
the network.
