APPENDIX A: MOBILE RADIO IPMESSAGE PARAMETERS
2003 IPMobileNet, Inc. 45 IPSeries MR User Manual / Rev. A / 08-Apr-03
Data Field Description
hostframing=Ethernet
Sets up Host Interface in Ethernet Mode.
A new parameter, “Ethernet”, has been added to the existing “Host Framing” command.
Before typing in the command, the radio must be unlocked. The command is effective
immediately. When host framing is set to Ethernet, the radio will try to use the Ethernet
interface first. If the Ethernet link status is bad, the radio will switch back to the SLIP
interface. The radio does not support both SLIP and Ethernet interfaces concurrently.
Therefore, if both the serial and Ethernet interfaces are physically connected to the host, it
is very important that the SLIP2IPMN dial-up is disabled. The TCP/IP property for the
Ethernet interface of the PC must be configured with an IP address different from the
SLIP2IPMN’s IP address. The default gateway address must be set to be the same as the
mobile radio’s IP address. If the PC is configured to obtain the IP address dynamically, the
mobile radio’s DHCP Server feature must be enabled first (see DHCP Server command
below).
Default Value = Ethernet, nostatus
dhcpclient=enable or
dhcpclient=disable
Enables/Disables DHCP Client.
Use this command to enable or disable DHCP. Before typing in the command, the radio
must be unlocked. Once the command has been entered, the radio should be reset with
the “reboot” command.
When DHCP Client is enabled, upon resetting, the mobile radio will obtain the IP addresses
and netmasks of the mobile radio itself, the PC and the VIU over-the-air from the IPNC.
The base station where the mobile radio is connected must be configured with
“dchprelayagent” enabled. Also, the IPNC DHCP server must be set-up and activated.
When DHCP Client is disabled, the mobile radio’s IP address and netmask must be
configured manually using the “ipaddress” command.
Default Value = disable
dhcpserver=enable or
dhcpserver=disable
Enables/Disables the DHCP Server.
Use this command to enable or disable the DHCP server capability of the mobile radio.
Before typing in the command, the radio must be unlocked. Once the command has been
entered, the radio should be reset with the “reboot” command. When DHCP Server is
enabled in the mobile radio, the PC connected to the radio’s Ethernet port can be set-up for
dynamic IP address configuration. DHCP Server can be enabled/disabled independent of
the state of DHCP Client. If DHCP Server is enabled but DHCP Client is not, the radio will
generate the IP addresses for the PC and VIU according to rules of the IPNC subnet
addressing described in the IPNC Installation Manual.
Examples:
1. Mobile Netmask:255.255.255.0, mobile:[phone], pc:172.16.20.10,
viu:172.16.21.10
2. Mobile Netmask:255.255.254.0, mobile:[phone], pc:172.16.40.10,
viu:172.16.42.10
Default Value = disable
suspendtx=n
Enable/Disable Unlicensed Frequency Restriction.
Where “n” is a decimal number range from 0 to 32767. Use this command to enable or
disable the feature of prohibiting transmission on unlicensed frequency channels. Before
typing in the command, the radio must be unlocked. The command is effective
immediately. When the “suspendtx” parameter is set to zero, the feature is disabled. In this
case, the radio is not prohibited to transmit even if it has not received anything from a base
station. On the other hand, if the parameter is not zero, the radio will NOT send until it has
received from a base station. Once the radio has received from the base, it will begin
sending but will stop further transmissions if it has failed to receive from a base station after
the period, in seconds, specified in the parameter.
When “testmode” is set to 1 in the
radio, “suspendtx” should be set to zero.
Default Value = 0
