WL800H-A DESCRIPTION
WL800H-A it contains both high temperature resistance 3 axis accelerometer sensor and 3 axis fluxgate magnetometer sensor,the inclination and toolface data measured by 3 axis accelerometer.the azimth data measured by 3 axis magnetometers. In addition,the WL800H-A can meausre the total acceleration,total magnetic intensity, magnetic tool face angle,magnetic well inclination,temperature.
WL800H-A uses ASCII to communicate through two-way TTL interface.The WL800H-A Software includes a mode for automatically sending data.
Features:
● Small size
● Rugged sturcture
● 175℃ high temperature resistance.
● High accuarcy
● Customized outlook of size and installation.( StandardΦ31mm ×384mm)

Electrical Interface:
WL800H-A adopts MDM9SH003P connector. The functions of connector leads toare shown in table 2.The input voltage range of WL800H-A is +10V~+36V. UART or RS232 serial communication interface is adopted, and the UART interface is compatible with TTL and CMOS levels.The default baud rate is 9600, with a stop bit and no synchronization bit. Users can change baud rate by setting parameters in the sensor EEROM.The WL800H-A can use two communication protocols:
1)The ASCII
The ASCII protocol is based on sending ASCII characters (instructions) to WL800H-A to get data.To respond to commands, send data to ASCII data streams including carriage return and line feed, which are easily displayed on computer display terminals.
2) Binary
Binary protocol is used for high-speed data transfer between MCUS.In this mode, 1 byte is sent to request data, and WL800H-A replies with multi-byte packets, including the required data, data header, check bit and data tail.
WL800H - A MDM connector lead definition as shown in figure 2, which has a connector between the up and down through line, some through wire twisted together by sensors, avoid penetration influence on magnetic flux gate line current, you need to use twisted together line as the power cord, and through the current shoulds not be too large, up and down the connector of the power input and output power line inside the sensor directly connected.

COMPUTER(PC) INTERFACE
The communication interface of WL800H-A sensor is UART (TTL/CMOS compatible) serial interface.In the standard configuration, data is transferred to the WL800H-A via the RX port and output from the WL800H-A via the TX port.The default baud rate is 9600 with one stop bit and no parity bit.
