Slave system
If an external system is used to provide the transmit trigger, the
trigger signal must be connected to one of the TrigIn inputs on
the GPT Auxiliary connector. When activated. the trigger signal
from the external system will allow the EQ60 system to
transmit.
If more than one GPT is used by the Slave system, the input
trigger must be connected to all the GPT units in parallel.
Two TrigIn inputs are available for either positive or negative
triggering. The TrigIn - input is sensitive to a high-to-low
transition.
Connect the ground wire to one of the Ground pins (18-22).
Note If the EQ60 system comprises more than one GPT unit, the
external trigger must be connected in parallel to every GPT.
The cable and connections to the GPT is shown on page 151.
