This chapter describes how to use a Hirose trigger connector and cable with a SMX-160
Series camera. Hirose trigger connector is included in the standard camera kit. Since a
cable is not included in the standard connector package, this document will guide on
how to use the connector with a cable.
Connector Pinout
A cable should be soldered to the connector according to the pin layout, which is
described in the table below.
Note: When soldering, any combination of pins can be used according to one’s specific needs.
● External trigger input (#1) - an input used to trigger a snapshot by applying a posi-
tive pulse (3.3V TTL, duration is not less than one period of clock frequency).
● Delayed synchronous shutter start (#2) - the same as Pin# 5 but delayed by the
time specified in the application program. Can be used to activate a flash.
● User programmed output (#3) - a user programmed output.
● External trigger input (#4) - the same as Pin# 1 but for negative triggering pulse.
● Synchronous shutter start (#5) - a pulse occurs at this output when camera is in
snapshot mode and snapshot control sequence begins. It can be used to trigger
another camera for synchronous operation or to activate a flash.
