inhand VG710 AC/DC Adapter Installation Guide
Introduction
1-Wire is a device communication bus system designed by Dallas Semiconductor Corp. that provides low-speed data, signaling, and power over a single conductor. It is typically used to communicate with small inexpensive devices such as digital thermometers and iButton devices. iButton® devices are small, durably packaged modules with globally unique digital addresses.
With its integrated 1-Wire interface, VG710 acts as bus master could communicate with iButton device or 1-Wire thermometer.
Users should first correctly install their 1-Wire device, and then they can check their 1-Wire device detail via VG710’s WebUI.
Install your 1-Wire device
The following figure shows 20-pin IO connector of VG710, which includes 1 Wire
interface support.
The following table details the 20-pin IO connector function assignment, and pin 3 is reserved for 1-Wire application.
PIN| Terminal Name| PIN| Terminal Name| PIN|
Terminal Name
---|---|---|---|---|---
1| 485-| 8| A14/D14| 15| DO1
2| CANL| 9| Al2/D12| 16| GND
3| 1-Wire| 10| GND| 17| A15/D15/WHEEL TICK
4| DO4| 11| 485+| 18| A13/D13
5| DO2| 12| CANH| 19| A11/D11
6| GND| 13| GND| 20| GND
7| A16/D16/FWD| 14| DO3| |
When install your 1-Wire device, you should connect its DQ pin to pin 3 of
VG710. Also you should connect its VDD and GND pins to GND pin of VG710. Make
