Networked Absolute Inclinometer
T7
The T7 is available in several interface and protocol options. The physical interface can be RS232, RS485 or US Digital's CAN (Controller Area Network). The protocol can be either US Digital's serial protocol or Modbus RTU. The RS232 version supports a single T7 with up to 100 ft of cable. For users that need longer cable lengths or multiple T7s on a single bus, the RS485 or US Digital CAN (Controller Area Network) version can be used. The USD-CAN protocol allows a network of up to sixty-four T7s to be connected to a single host. Power for each T7 is supplied over the CAN network cable. The host accesses the USD-CAN T7s through US Digital's low cost CANA-232/CANA-485 adapter module. This module allows the host to access each T7 on the network using simple, easy serial port commands, just like the RS232 version. The RS485 version supports up to 32 T7s on the bus.

Enhanced Serial Interface Module for the Multiprotocol Excalibur 4000 Family of Carrier Boards
M4KSerialPlus
The M4KSerialPlus is an enhanced serial interface module for the multiprotocol Excalibur 4000 family of carrier boards, that includes several advanced features such as a high baud rate and high throughput. This module supports up to four independent channels of serial communications, each of which can be selected as RS-485, RS-422 or RS-232. The module operates independently of the host computer, reducing the need for host intervention.The M4KSerialPlus module is based on the Exar XR16M570 Universal Asynchronous Receiver/Transmitter (UART). The device is compatible to industry standard 16550 UARTs. Each of the M4KSerialPlus’s four channels contains a transmit FIFO capable of holding up to 16384 bytes and a receive FIFO capable of holding either 16384 receive bytes or 5460 bytes with a 32-bit Time Tag associated with each byte. These large buffers allow application code to transfer large quantities of data with a single non-blocking subroutine call. The 32-bit Time Tag on receive channels is very useful for synchronizing serial data with data from other modules on the 4000 board or on other interface boards. Each channel has a programmable baud rate of up to 10 Mbps and can be configured as RS-232, RS-422 or RS-485.The M4KSerialPlus module is supplied with C drivers, including source code.
