3.7. FIO [ D ] Flexible IO
The Tech Series FIO Flexible IO version of the RV-M21 and RV-M22 series radio
modems is ideal for SCADA and telemetry. Here is a summary of the standard FIO
features. If you need other IO features or additional IO, please contact Raveon sales
personnel.
The FIO connector on the product is DB15 female.
The IO modes FIO pins can be set to are:
A
: Digital TTL Input, B: Digital TTL Output,
C
: Open Drain MOSFET output. Please see the following table to see which FIO ports
can be used for which IO modes.
