A.5 Proxim RangeLAN2 Model 7520 Access Point
Image n/a
Network Interfaces Ethernet 10BASE2 (Thin) BNC
Ethernet 10BASET (Twisted-Pair)
Data Rate 1.6 Mbps – RangeLAN2
10 Mbps – Ethernet
Media Access Protocol RangeLAN2 CSMA/CA
Ethernet Compatibility Ethernet packet types and Ethernet Addressing
Frequency Band 2.4-2.483 GHz (in the U.S.)
(spread spectrum frequency hopping)
Independent Channels 15
Output Power 100 mW
Size PCMCIA Type II card
ETSI Testing For purposes of ETS 300 328 type testing, the RangeLAN2
Access Point was tested in host computers over a temperature
range of –20°C to +55°C.
Operating Temperature -20°C to +60°C.
UL Listed Power Supply The RangeLAN 2 Access Point requires an external power
supply. If you have elcted not to purchase the external power
supply from Proxim or need a replacement, you must use only
a UL listed, Class 2 power supply, rated min. 1A at 12VDC.
A.6 Quatech DSP-200/300 Dual Channel RS422/485 PC Card
The DSP-200/300 provides two independent RS-422/RS-485 asynchronous serial
communications interfaces for systems equipped with PCMCIA Type II and/or Type III
expansion sockets. The RS-422/485 serial ports may be configured to operate in either
the full duplex or half duplex mode.
Bus Interface PCMCIA PC Card Standard 2.1 compliant
Physical Dimensions Type II PCMCIA card (5mm)
Maximum Baud Rate 120K
Power Requirement +5V 35.85 mA (typical)
45.87 mA (Maximum)
Connector Adapter to 2 standard female D-9
A.7 Greystone Peripheral Type Adapter TA-50
The Type Adapter converts any PCMCIA compliant Type I or II card slot to handle
Type III (or thicker) cards as needed. As such, it permits simultaneous use of a Type III
device, such as the Calluna PC Hard Card, and a network adapter. With the Type
Adapter, a PC Card can be inserted for file backups without interrupting File Server
activity on the OPS LAN. Additionally, the TA-50 substantially reduces heat damage
caused by prolonged confinement in the ThinkPad’s unventilated PC Card slot. At the
present time, no PCMCIA slot extender, including the TA-50, is certified for flight.
