Data Fwd Timer
This field selects the timing between data blocks in a transmission to accommodate some RTU’s special timing
requirements:

Normal - 15 ms option (default)

Fast - 5 ms option (do not use for baud rates below 2400 b/s)
Break
This field selects the unit’s response to break signals (protocol dependent) on the COM Port:

Ignore break - unit does not transmit or receive break signals

Transmit break - unit transmits and receives break signals
Deferred Rx-Data Delivery
This field sets the period of time the unit waits until delivering received data to the COM Port. Range is 0 to 255 ms in 1 ms
intervals (keeps delays minimum for protocols susceptible to inter-character delays).
External I/O 1 (Green)
These radio buttons select configuration of Pin 3 on the Power - I/O Connector (green wire):

Analog Input - Analog input is an option on units not equipped with the cooling fan option - can be used to monitor
an external voltage (0 to 10 volts). Monitoring is from the Offline Diagnostics screen

Tx Controlled Fan - Selecting this option will cause the unit to turn the fan ON at the start of a transmission and
OFF after a predetermined timeout (TX Controlled Fan Timeout) at the completion of a transmission. The length of
time the fan is on is the length of the transmission plus the timeout time. This option is displayed for versions of
firmware that support fan control output based on transmissions (Ver 2.04 and later).

Digital Output - Digital Output is an option for units not equipped with the cooling fan option. This connection can
be used to control the open-collector transistor on the connector. The open-collector output can sink a maximum
current of 100 mA when the modem board rev is 0 or 1. The output is controlled from the Offline Diagnostics
screen. Figure 22 shows the Field Programming Software interface for Digital I/O.
Digital Output Circuit and Interface Parameters
Hardware setup for the Integra-TR utilizing Digital I/O should be completed following the circuit diagram in Figure 20 and
the wire diagram in Figure 21.
