2.4.8 Digital I/O

The Digital I/O port, J5 connector (

Section 2.5 on page 11

), provides a connection to both digital inputs and outputs.

Digital inputs can be set to provide many functions, including most keypad functions except MENU, numeric keypad and

softkeys. Digital inputs are active low (0 VDC) and inactive high (5 VDC). Use the Digital I/O menu to configure the digital inputs.
Digital outputs are used to control relays which drive other equipment. Outputs are designed to sink, rather than source current.

Each output is an open collector circuit, capable of sinking 20 mA when active. Digital outputs are active when low or at 0 VDC,

with reference to the 5 VDC supply.
Use the Digital I/O menu to set the function of the Digital I/O pins to OUTPUT and then use the Setpoints menu to configure the

digital outputs. See

Table 2-9

for the pin assignments for the J5 connector.

2.4.9 Memory Card Slot

The memory card slot, J6 connector (

Section 2.5 on page 11

), accepts microSD cards and provides storage space for

configuration settings (

Section 12.3 on page 85

) and Truck IDs. The 682 comes with an 8 GB microSD card (PN 164939) and

the memory card slot supports up to a 2 TB microSD card.

2.4.10 Micro USB Device Communications

The Micro USB port, J7 connector (

Section 2.5 on page 11

), provides a connection point to a PC only. It appears as a Virtual

COM Port and is assigned a “COMx” designation. Applications communicate through the port like a standard RS-232

communications port.
The driver must be installed on the PC before the Micro USB device port can be used. With the PC and 682 powered on, connect

a USB cable from the PC to the Micro USB connector (J7) on the 682. The PC recognizes if a device has been connected, and

attempts to install the driver needed to make it work. The driver can also be downloaded from

www.ricelake.com

NOTE: With a PC connected to the Internet and running Windows 7 or later, the operating system may install the drivers

automatically.

When the individual drivers are installed, a new COM Port designation is assigned for each physical USB port the 682 is

connected to on the PC.
For example, if the PC has two physical RS-232 COM Ports, they most likely are designated COM1 and COM2. When

connecting the 682 to a USB port on the PC, it is assigned the next available port designation, or in this case, COM3. When

plugging into the same physical USB port on the PC, the port designation is again COM3. If plugging into another physical USB

port on the PC, it is assigned the next available designation, in this case COM4.
After the drivers are installed, use Windows

Device Manager to determine the COM Port designation which was assigned to

the USB port, or open an application to be used with the 682, such as Revolution, to see which ports are available.
Configuration of the Micro USB port is done in the USBCOM sub-menu under PORTS in

Setup

mode.

The port can be configured as either a command (CMD) port for EDP commands and printing, or as a data streaming port.

Other settings include termination character(s), echoes, responses and end-of-line delay (

Section 4.5.4.2 on page 38

NOTE: If a computer application has an open communications connection through the Micro USB device port and the

physical cable connection is interrupted, a soft reset must be performed on the 682 or the power must be cycled to the 682;

the connection in the computer application must be disconnected and then reconnected before it continues to

communicate with the 682.

NOTE: For the Micro USB device port, it does not matter what the settings are for baud, data bits, parity and stop bits in the

computer software. The port communicates in the same way regardless of these settings.

NOTE: This port is not a host port and is not to be connected to other devices such as keyboards, memory sticks or printers.
