Both Ports
The terminal may be connected to either port.
The factory setting is based on the type of transceiver. A setting of “2” will be used
with Ethernet products and Mirrored Bit products, a setting of ”3” will be used
otherwise. Setup mode is invoked by sending a "U" (Shift-U) to the Diagnostics
port or by pressing/toggling the Set-up button/switch, if available. OEM boards
may also enter Setup when Pin 2 is grounded. The Ethernet reset button will NOT
put the unit into Setup mode. Ethernet transceivers must use the “U” option.

The Main Data Port is the RS232 port. The Diagnostics port is a 3-pin connector
on the rear panel of the FGR2-CE and the OEM “Mini” series transceivers. The
diagnostic cable for this port (ASC0409DC) is available from FreeWave. The
FGR2-C OEM modules use a 2-row, 2 mm female connector. The diagnostic cable
for this port (ASC2009DC) is available from FreeWave.

TurnOn/OffDelay

TurnOnDelay- Sets the delay between when the line drivers are turned on and
when the data leaves the data port. This setting can be adjusted for a 1-9mS
delay.
when the data leaves the data port. This setting can be adjusted for a 1-9mS
delay.
TurnOffDelay- This setting specifies the time after the end of transmission of a
character to the RS485 bus that the transceiver stops driving the bus and releases
the bus to other devices. The units are ¼ of a character with a range of 0-9. An
entry of 4 means a delay equivalent to the duration of a full character. Default is
zero delay.

entry of 4 means a delay equivalent to the duration of a full character. Default is
zero delay.
For data rates of 1200 bits/S or slower, avoid setting the TurnoffDelay parameter
higher than 4. At those rates the functionality of the microprocessor changes so
that a TurnoffDelay of 5 will have the same effect as if set to 1, and a setting of 6
will have the same effect as 2, and so on.

Note: TurnOffDelay must be set to a value of at least 4 for RS4xx operation.
