to the COM1 Baud rate field
The COM1 Baud rate field determines the speed of
communications between the E2 and an RS232 device
(such as a satellite link or PC).
The baud rate selected in this field should correspond
with the baud rate for the RS232 device. For example, if
connecting a PC to this port, the PC’s COM port should
be set up to communicate at the same rate as what is set
in this field.
There are multiple options to choose from. Select one
of the options below using  (LOOK UP) depending
on the type of connection.
• 1200 Baud (devices that operate at 1200)
• 2400 Baud (devices that operate at 2400)
• 4800 Baud (devices that operate at 4800)
• 9600 Baud (recommended for satellite)
• 19.2 Kbaud (recommended for modem)
• 38.4 Kbaud (recommended for modem)
• 57.6 Kbaud (recommended for modem)
• 115.2 Kbaud (recommended for direct connect)
10.11.2 I/O Network Baud Rate
When a comport is set to I/O Net, the I/O Network
baud rate is the rate at which the E2 will communicate
with input and output boards on the RS485 I/O Network,
and is located directly below the RS232 Baud rate field.
Press  to select the baud rate. The appropriate
baud rate is 9600 baud.
NOTE: If a baud rate is the controller must be
rebooted (turned OFF then ON again) to make
the baud rate change occur.
