This chapter describes how to use a Hirose trigger connector and cable with a SMX-150
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.
Note For the SMX-150M camera, Pin#3 of the External Trigger Connector pinout (User programmed output) is
available only for cameras with firmware 1.3.8.14.34 or higher. For previous versions of the cameras (with lower
firmware version) it is not used.
