Pin No. | Name | Description |
|---|---|---|
1 | Cable ID | Cable detection input. |
2 | 5 V | USB 5 V signal. This is an input to indicate that the system is connected to a host. Input power is 5 V +/- 5%, 500 mA max. |
3 | GND | Power supply ground input and signal ground reference. |
4 | RS-232 TXD | Serial Mode: Serial data transmit output. It drives the serial data receive input on the host device. |
5 | USB D+ RS-232 RXD and RS-232 TXD (Host) | USB: D+ Signal, 1/2 of differential pair for USB Communication. Serial Mode: Serial data receive input. It is driven by the serial data transmit output on the host device and Serial Mode: Data transmitted from the host. |
6 | RS-232 RTS | Serial Mode: Request-to-send handshaking output line. It may be optionally used by the scanner to signal to the host device that data is available to send. It can only be utilized in conjunction with the host CTS line. |
7 | USB D- RS-232 CTS and RS-232 RTS (Host) | USB: D- Signal, 1/2 of differential pair for USB communication. Serial Mode: Clear-to-send handshaking input line. It may be optionally used by the host device to signal the scanner that it may commence transmitting data. It can be used only in conjunction with the host RTS line. |
8 | DOWNLOAD | This signal is used to begin the Flash Download operation when asserted high. |
9 | TRIGGER* | External Trigger input. This input is connected to a pin on the microcontroller, which is connected to a pull-up resistor on the microcontroller and will act as a device trigger when grounded. |
10 | NC (No 12 V) | No connection |
