Question:  I have a Matrix +3 frame using a FOR-22 interface card to activate an attached 2-way radio.  I'm activating the 2-way radio key on a i-station using the logic input 1 or logic input 2 controls to activate talk key 1 or talk key 2.  Everything is configured properly in software but when I activate the i-station logic inputs the talk keys on the i-station activate, but the relay doesn't light up / activate.  If I go to the key on the i-station and activate it locally there the relay does light up / activate.  Is it possible to activate the FOR-22 relay from the i-station logic input? 
Answer:  Yes the FOR-22 relay can be activated from the i-station logic input set for talk key 1 or 2 activation.  If the FOR-22 interface card is declared as a 2-way radio interface one of the presets for a 2-way radio key is non-latching functionality.  If the key is non-latching the i-station logic input will not activate the relay associated with the FOR-22 talk key.  To fix this go into the PGM-WIN software Global Advanced screen, find the FOR-22 interface card and unselect the non-latching key operation and apply the change.  This should allow the i-station logic input to activate the FOR-22 talk key and activate the associated relay when the logic input is activated.
