Option Installation Instructions
The PageWriter TC20 cardiograph supports the AmbiCom WL150N USB wireless adapter,
available as option D23.
The adapter is a USB dongle that includes an integrated diversity antenna with enhanced
transmit power and receiver sensitivity, and with superior delay spread and roaming
capabilities. It delivers dependable connectivity in almost all demanding clinical
environments, including those with limited access point availability, and those with numerous
and competing wireless devices.
The AmbiCom adapter is compatible with both the 802.11b and g wireless standards, and
operates in the 2.4 GHz section of the radio frequency spectrum, providing a data transmission
rate of up to 54Mbps.
Configuration is simple, using the Microsoft NetUI utility to set up and control network
connections and security settings.
Additional information about the AmbiCom adapter is available at the AmbiCom website,

Supported Security Options
Supported Security Options
Authentication is supported through an integrated 802.1x supplicant supporting authentication
using pre-shared keys, as well as two extensible authentication protocol
EAP-TLS and PEAP-MSCHAPv2.
Data privacy is ensured via encryption and decryption using AES (WPA2), TKIP (WPA), or
WEP. A comparison of the supported EAP types used with 802.1X authentication and the
certificate requirements for the different authentication methods is included in Table 1.
You configure all wireless LAN security and connection options on the network configuration
screens accessed through the
NOTE Some authentication methods may require that a valid authentication certificate be loaded and enabled
on the cardiograph. For details, see “Step 2. Loading Authentication Certificates and Keys” on page 6.

Step 1. Inserting the Wireless USB Adapter
CAUTION Only use AmbiCom wireless LAN adapters that have been purchased from Philips. The use of non-
approved wireless LAN devices with the PageWriter TC cardiograph is not tested or supported, and
Philips does not guarantee cardiograph operation or wireless LAN connectivity.
To enable the cardiograph for a wireless connection
Insert the AmbiCom USB adapter (USB dongle) into the USB port on the side of the
cardiograph.
If the port is already in use, that is, a USB memory stick with ECGs or worklist entries is
currently in the port, remove the memory stick and replace it with the wireless USB
dongle.
The dongle illuminates when it is properly connected.
A Wireless USB dongle
You can now load certificates, as described in the next section, “Step 2. Loading
Authentication Certificates and Keys” on page 6.
To remove the USB dongle
Pull the USB dongle straight out from the port.

Configuring Wireless Adapter Settings
Step 2. Loading Authentication Certificates and Keys
The cardiograph supports two types of certificates: general and user.
For general certificates, use the Load Certs button to load and enable certificates (for
example, 509 certificates and private keys) from a USB memory stick into the NetUI
utility’s certificate directory.
For user certificates (for example, EAP-TLS), use the Import Certs button to launch the
Microsoft Certificate Utility, which allows you to import a user certificate and private key
(located in the NetUI utility’s certificate directory) into the Microsoft System store.
Table 3 Load Certs and Import Certs options
If the encryption method you are using requires a certificate or an optional private key, have
the network administrator generate the certificate/private key as required, and load these files
onto a USB memory stick.
CAUTIONS Do not insert a USB memory stick into the cardiograph, or remove a USB memory from the
cardiograph, when the cardiograph is acquiring ECG data from a patient.
The PageWriter TC cardiograph only supports the USB memory stick that is available for purchase
as an optional accessory from Philips. Philips does not guarantee that other USB memory sticks are
compatible with the PageWriter TC cardiograph.
