Inter-Packet Gap Settings
For radios operating in Packet Mode, the inter-packet gap is a timing set-
ting used to delimit a packet on the serial interface. Too short of a time
can cause serial streams to be combined into one large packet instead of
two smaller ones. Too long of a time can slow down the communica-
tions channel.
Inter-Packet Gap Settings for
COM1
and
COM2
are made using the
Con-
figuration>>Radio>>Packet Settings
screen. See Page 44 for details.
Baud Rate Setting
The higher the baud rate, the faster the communication speed of the
serial link connected to the
COM
port. However, this setting has no direct
effect on over-the-air transmission speed.
The modem baud rate is set using the
Configuration>>Communication
Ports>>COM1/2 Port Settings
screens. See Page 63 for details.
Ethernet Settings
The local Ethernet connection must be configured to conform to the
needs of the local Ethernet network. The
Configuration>>Communication
Ports>>IP Configuration
screen is used to set/view these settings. Here are
some general points that apply to Ethernet settings:
• The radio's Ethernet settings must be configured in order to com-
municate over the LAN to which it is connected.
• It must be known whether or not a DHCP server is active in a net-
work to make use of the radio’s DHCP setting.
• If DHCP is available, it can be enabled. Once enabled, it can take
a few minutes before the radio obtains an IP address, which will
be displayed in the
Current IP Address field
.
• If DHCP operation is unavailable (or is not desired), then a static
IP address may be manually set. IP network setup is beyond the
scope of this manual. Consult your network administrator.
• As a quick reference, a typical LAN setup might appear as fol-
lows:
Static IP Address
192.168.1.101
Static IP Netmask
255.255.255.0
Static Default Gateway 192.168.1.1
DHCP
Disabled
