3.1.12 ICOM Ports

ICOM ports are virtual ports. The ProPak6 has three shared ICOM ports for Ethernet, Wi-Fi and Cellular.
The transport/application layer of the ICOM ports can be configured using Transmission Control Protocol
(TCP) for internet IP or User Datagram Protocol (UDP) a slower and less reliable IP protocol. If using
TCP, only one connection at a time is supported.
Although each port can be configured independently, the system only uses one DNS server at a time.
Refer to DNSCONFIG command for Ethernet DNS and the WIFICLICONFIG command for configuring
DNS for a static Wi-Fi network. (If using DHCP, DNS is automatically set.)
The following are the default ICOM configurations:
• ICOMCONFIG ICOM1 TCP :3001
• ICOMCONFIG ICOM2 TCP :3002
• ICOMCONFIG ICOM3 TCP :3003
Each ICOM port can act as a server (waiting for an external connection to be made) or as a client
(actively establishing a connection to a specific port).
Refer to the OEM6 Firmware Reference Manual
DNSCONFIG, IPCONFIG, ICOMCONFIG, the ETHCONFIG command and the Wi-Fi WIFICLICONFIG
command.
In this manual, refer to Section 2.9.2, FTP Server and ICOM Ports on page 33 for details on securing
ICOM ports.

3.1.13 Serial Ports

The receiver communicates with the computer or terminal via a serial port. For communication to occur,
both the receiver and the operator interface must be properly configured. The ProPak6's COM1, COM2
and COM3 default port settings are as follows:
• 9600 bps, no parity, 8 data bits, 1 stop bit, no handshaking, echo off
Connection Name
Connector location
Default configuration
Alternate configuration
The data transfer rate determines how fast information is transmitted. Take for example a log whose
message byte count is 96. The default port settings allows 10 bits/byte (8 data bits + 1 stop bit + 1
framing bit). It therefore takes 960 bits per message. To get 10 messages per second then requires 9600
bps. Please also remember that even if you set the bps to 9600 the actual data transfer rate is lower and
depends on the number of satellites being tracked, data filters in use, and idle time. It is therefore
suggested that you leave yourself a margin when choosing a data rate (115200 is recommended for most
applications).

Although the receiver can operate at data transfer rates as low as 300 bps, this is not
desirable. For example, if several data logs are active (that is, a significant amount of
information needs to be transmitted every second) but the bit rate is set too low, data
overflows the serial port buffers, causing an error condition in the receiver status that
results in lost data.
