7: Data Communication and Host
Modes

The PinPoint‐E plays the part of a HOST when a computer or
another device is connected directly to its port and routes data
to/from the connected device to the cellular network.
Caution: The PinPoint-E moves data from one port to the cellular
network in a simple one-to-one routing. It does not employ a routing
table or any complicated routing protocol.
Tip: If you need to have one-to-many routing, you can connect the
PinPoint-E to a router. The router would provide the multiple routing
and the PinPoint-E would provide one-to-one for the router to the
cellular network and the Internet.
As the host, the PinPoint‐E can use different communication
modes:
Basic Modes
•
AT: The PinPoint‐E accepts and responds to standard AT
commands.
•
PassThru: Direct connection to internal hardware (OEM
Module) of the PinPoint‐E.
•
Telnet: The PinPoint‐E auto‐answers TCP connections to
allow terminal emulation using either a local Ethernet
connection or remotely using the cellular connection.
Tip: By default, the PinPoint-E is in AT Mode and allows AT
Commands to be entered via terminal connection (through the local
port connection) or remotely (through the cellular network). PassThru
Mode can only be exited by resetting the PinPoint-E. All serial modes
are entered by use of a startup mode command.
Serial Modes
•
PPP Mode: The PinPoint‐E uses PPP to communicate with
a device or computer connected to the serial.
•
SLIP Mode: The PinPoint‐E uses SLIP to communicate
with a device or computer connected to the serial.
