Not Connected * Pins 1 and 25 are connected together internally. 851000292 (Rev. B) Power Supply Power can be supplied to the scanner through the pins provided on the 25-pin connector used for communication with the host. The power must be between 10 and 30 Vdc only. SCANNER USER INTERFACE VS GND CHASSIS V+ (10-30 Vdc) GND Inputs The yellow LED is on when the External Trigger forces a current flow through the EXT TRIG+ and EXT TRIG- pins. This input is optocoupled and can be driven by both an NPN or PNP type command. The connections are indicated in the following diagrams: SCANNER Vext 30 Vdc max.
