7.4 Connecting the WiComm-1 to a Wireless PC

LAN (Ad-Hoc Mode)

The connection between the WiComm-1 and a wireless PC LAN is a way to manage the WiComm-1 and serial

devices connected to the WiComm-1 from a PC equipped with a wireless LAN card supporting 802.11b or 802.11g.

By Web or Telnet, set the operation mode of the WiComm-1 to Ad-Hoc and set SSID information and IP

information. A user can construct a wireless network between the WiComm-1 and a wireless LAN card by setting

the same information as the SSID of the WiComm-1 in a PC or a device equipped with a wireless LAN card.
