GPRS Signal:  Signal strength required before attempting to connect to the 
GPRS network. This may help reduce the number of connection 
attempts in weak coverage areas. 
Cell Keep-Alive:  Some networks may require sending a small packet periodically 
to maintain the assigned IP address. 
Cell Username:  Username for cellular PPP connection, if required. 
Cell Pass:  Password for cellular PPP connection, if required. 
GPRS APN:  Access Point Name for establishing GPRS connection. 
Iridium/Sat 
Iridium COM Speed:  Iridium modem COM speed. 
Iridium Portable:  If enabled, the i50 will add its ID to each packet it sends over 
Iridium. This increases packet size, but allows modems to be 
swapped between units. 
PDT COM Speed:  PDT satellite modem COM speed. 
RF 
RF COM Speed:  RF modem COM speed. 
RF Serial Config:  Serial settings for RF port. 
Ack Time:  Time to wait after receiving data before replying over an RF 
modem. This provides time for half-duplex modems to switch 
from transmit to receive mode. 
Kenwood:  Kenwood radio settings. Enabling the Software ACKs option will 
ensure data is received by the server, but will increase radio 
traffic. With this disabled, the i50 will rely on radio ACKs only. 
When WAN mode is enabled, the i50 will automatically switch 
the radio channel/zone based on waypoint locations. Selecting 
the Transparent option causes the i50 to send raw data 
packets, which requires the Kenwood radios to be configured 
for transparent data. 
Kenwood Base TX Fleet/Type:  Kenwood base radio fleet ID (Fleetsync) or ID type (NXDN). 
Together with the Kenwood TX Base ID setting, this is used as 
the destination when sending data over a Kenwood radio. 
Kenwood Base TX ID:  See above. 
Kenwood Base RX Fleet:  Kenwood base radio fleet ID (Fleetsync only). Not used for 
NXDN networks. See below. 
Kenwood Base RX ID:  Kenwood base radio ID (combined with Kenwood RX Fleet ID 
for Fleetsync). The i50 will only accept data from this radio ID. 
Globalstar 
Globalstar COM Speed:  Globalstar modem COM speed. 
Globalstar Server IP:  DataGate server address when sending data over Globalstar. 
Also used to allow data through the Wi-Fi firewall. 
Backup Globalstar Server IP:  Backup address, used when remotely switching servers. 
Globalstar Timeout:  This timer limits how long a Globalstar connection will stay 
active if no data is sent or received. 
Globalstar RX Port:  UDP RX port for Globalstar. 
Globalstar TX Port:  UDP TX port for Globalstar.
