Installing the RedLab E-1608
Unpacking
As with any electronic device, you should take care while handling to avoid damage from static electricity. Before removing the device from its packaging, ground yourself using a wrist strap or by simply touching the computer chassis or other grounded object to eliminate any stored static charge.
Contact us immediately if any components are missing or damaged.
Installing the software
Note: Before installing the RedLab E-1608, first install the software you plan to use with the device.
Installing in a Windows environment
Universal Library, Universal Library for Android, and InstaCal
Universal Library and InstaCal software are included on the CD that ships with the device. Install Universal
Library and InstaCal when you want to develop data acquisition applications using Windows programming languages.
Universal Library for Android is a software API that installs with the Universal Library and InstaCal. Use this programming library to develop apps on the Windows platform for deployment to Android-based devices. For instructions about deploying apps from Windows to an Android environment, refer the UL for Android
Example Projects topic in the Universal Library for Android Help included in the installation.
Connecting the external power adapter
Power to the RedLab E-1608 is provided with the 5 V external power adapter (PS-5V1AEPS). Connect the adapter cord to the power connector on the RedLab E-1608 device, and plug the AC adapter into an electrical outlet.
The Power LED turns on when 5 V power is supplied to the RedLab E-1608. If the voltage supply is less than
3.3 V or more than 5.9 V, the POWER LED does not turn on.
Refer to Figure 2 Seite 10 for the location of the
Power LED.
Connecting the RedLab E-1608
The RedLab E-1608 requires a TCP/IP and UDP connection to a network or computer. Use the standard
Ethernet cable provided to connect the RedLab E-1608 to a 10Base-T- or 100Base-TX compatible Ethernet port, hub, or switch.
When connecting the RedLab E-1608 for the first time, make sure that you connect to a local network with
DHCP enabled.
If you are unsure whether you have access to a local network or that DHCP is enabled on that network, you should use a direct connection to a Windows PC.
It may take a minute or two to detect the device and assign the address. The green Link/activity LED on the lower left of the Ethernet connector turns on when there is a valid Ethernet link, and blinks when network activity is detected.
Once the RedLab E-1608 is physically connected to the local network or PC, you can run the software (InstaCal for example) to establish a connection. If a connection cannot be established, make sure the device is using the
7
RedLab E-1608 User's Guide Installing the RedLab E-1608
Once a connection is established and you can communicate to the device, you can change the configuration for other network scenarios.
Configuring network settings
The following RedLab E-1608 network settings are software-selectable. Only one user at a time can connect to the RedLab E-1608 to configure network options on the device. For typical local networks, the default settings are recommended.
Address mode settings
The address mode setting determines whether the default IP parameters (IPv4 address, subnet mask, and gateway) are assigned to the RedLab E-1608 or an auto-addressing method is used to assign these parameters.
DHCP or link-local enabled (default)
If connected to a network with a DHCP server, the service automatically assigns IP addresses to the RedLab E-
1608.
If the connected network does not have a DHCP server, the address stored in the default IP address is assigned to the RedLab E-1608.
If the RedLab E-1608 is directly connected to a Windows PC, a link-local address is assigned to the device. A link-local address is valid only for communications between the RedLab E-1608 and the PC to which it is connected
DHCP Only
Enables configuration by a DHCP server if one is available. The RedLab E-1608 is assigned an IP address shortly after it is powered up and attached to the network.
Link Local Only
The RedLab E-1608 is assigned a link-local IP address by the Windows PC to which it is connected. A linklocal address is valid only for communications between the RedLab E-1608 and the PC to which it is connected.
Static
The default IPv4 Address is manually configured on the RedLab E-1608.
IP address settings
The default settings of the following IP address are assigned to the RedLab E-1608 when automatic addressing is disabled or not available (DHCP or Link Local for example)
IPv4 address – The IP address that is stored on the device. The default IPv4 address is 192.168.0.101.
Subnet mask – The Subnet mask that is stored on the RedLab E-1608 . The subnet mask determines the number of bits of the IP address that is used for the host portion of the address vs. the number of bits used for the network portion. The default subnet mask is 255.255.255.000
Gateway – The gateway IP address that is stored on the RedLab E-1608. The gateway address of the device that bridges subnets within a network. The default gateway is 192.168.0.1
Connection code
A number between 0 (default) and 999999999. Change this number from its default of 0 to prevent other users from connecting to and configuring the device. The device remains visible to other users on the network, but connection by another user is not allowed.
Setting up the RedLab E-1608 for communication across networks
In order to communicate with the RedLab E-1608 from a computer connected to a different network – such as over the Internet – you must change the network configuration of the network router.
In the following procedure, the RedLab E-1608 is installed on the host LAN, and the computer is installed on the client LAN.
8
RedLab E-1608 User's Guide Installing the RedLab E-1608
Caution! This procedure should only be performed by a network administrator or computer professional.
Incorrect settings can significantly disrupt a network.
1. Assuming you have successfully connected to a local network, determine the IP address of the device. If the address was assigned by DHCP, it is recommended you change it to a static address by setting the default address to the address assigned and setting the device network configuration to static.
2. Configure the firewall/router to forward incoming traffic to the following ports to the IP address assigned to the device: o UDP:54211 (discovery) o TCP:54211 (commands) o TCP:54212 (scan data)
3. On the computer connected to the client LAN, manually enter the WAN address of the host router, and specify the ports that were forwarded to connect to the remote RedLab E-1608.
If the ports listed above are not available on your router, you can use the following guidelines to select different ports: The first port must be configured for both UDP and TCP. The second port must be adjacent to the first and configured for TCP. For example, you could use 54221 (TCP and UDP) and 54222 (TCP).
Configuring network alarms
You can use software to configure any digital output bit and/or each analog output channel to generate specific values to indicate when the device is connected and/or disconnected.
The settings can also be used to initialize an output to a specific value when the device connects or disconnects from the network.
Restoring factory default network settings
To reset the network configuration settings to the factory default values, complete the following steps (refer to
Device components Seite 10 for the location of this button):
1. Remove power from the device.
2. Press and hold the Factory reset button while re-applying power.
3. Hold the button for at least four seconds until both the Power and Activity LEDs blink , indicating that the settings have been restored to the factory defaults.
4. Release the button so the device continues startup with the default settings. If the button is released before the two
LEDs blink, the settings are not affected and the device starts up normally.
If InstaCal is open when default settings are restored, click the Refresh Boards button on the InstaCal toolbar to reflect the changes.
Calibrating the hardware
The Meilhaus Electronic Manufacturing Test department performs the initial factory calibration. Return the device to Meilhaus Electronic GmbH when calibration is required. The recommended calibration interval is one year.
Field calibration is not supported.

Functional Details
Analog input modes
The RedLab E-1608 can acquire analog input data in two basic modes – software paced and hardware paced.
Software paced
You can acquire one analog sample at a time in software-paced mode. You initiate the A/D conversion with a software command. The analog value is converted to digital data and returned to the computer. Repeat this procedure until you have the total number of samples that you want.
The sample rate in software paced mode is system-dependent and can range from 1000 S/s to 5000 S/s on local networks (lower over the Internet or wireless networks).
Hardware paced
You can acquire data from up to eight channels in hardware-paced mode. The analog data is continuously acquired, converted to digital values, and written into the FIFO buffer on the device until you stop the scan. The
FIFO buffer is serviced in blocks as the data is transferred from the FIFO buffer to the computer memory buffer. You start a continuous scan with either a software command or with an external hardware trigger event.
The maximum sample rate in hardware paced-mode from one to eight channels is 250 kS/s aggregate on local hardwired networks (may be lower over the Internet or local wireless networks).

10
RedLab E-1608 User's Guide Functional Details twisted pair cable. The maximum communication distance without using a repeater is 100 meters. You can send your data 100 meters at data speeds of up to 100 Mbps using only one Ethernet cable connected to your computer.
External power connector
Connect the 5 V external power adapter (PS-5V1AEPS) to this connector to provide 5 V external power to the
RedLab E-1608.
LEDs
The Power LED is steady green when external power between 3.3V to 5.9 V is supplied to the RedLab E-1608.
The Power LED turns off when:
power is not supplied by the external supply (make sure that the supply is fully connected to the power connector)
the input power is outside of the specified voltage range of the external supply (3.3V to 5.9 V ), causing a power fault
The RedLab E-1608 has an onboard voltage supervisory circuit that monitors the 5 V external power supply.
The Activity LED is on when there is a valid host connection, and blinks when a command is received or an analog input scan is running.
Ethernet connector LEDS
The green Link/activity LED on the lower left of the Ethernet connector is on when there is a valid Ethernet link, and blinks when network activity is detected.
The yellow Speed LED on the lower right of the Ethernet connector is on when the transmission speed is
100 Mbps, and off when the transmission speed is 10 Mbps or there is no link.
Factory reset button
Use the factory reset button to reset network configuration settings to the factory default values.
Refer to Restoring factory default network settings Seite 9 to learn about resetting these values.
Screw terminals
The RedLab E-1608 device screw terminals provide the following connections:

Signal connections
Analog input
You can configure the analog inputs for SE or DIFF mode. The input voltage range is software selectable for
±10 V, ±5 V, ±2 V, or ±1 V.
With SE mode, connect up to eight inputs to CH0x to CH3x . SE mode requires two wires:
Connect one wire to the signal you want to measure (
CH#x ).
Connect one wire to the analog ground reference (
AGND ).
With DIFF mode, connect up to four differential inputs to CH0H/CH0L to CH3H/CH3L . DIFF mode requires two wires plus a ground reference:
Connect one wire to the high/positive signal (
CHxH ).
Connect one wire to the low/negative signal (
CHxL ).
Connect one wire to the analog ground reference (
AGND ).
Floating voltage source
When connecting DIFF voltage inputs to a floating voltage source, make sure the DIFF input channel has a DC return path to ground. To create this path, connect a resistor from each low channel input to an AGND pin. A value of approximately 100 kΩ can be used for most applications.
Leave unused input channels either floating or tied to an AGND terminal. Source impedances should be kept as small as possible to avoid settling time and accuracy errors.
Figure 4 shows DIFF channels 0-3 connected to a ground path resistor.
Figure 4. DIFF connections with ground path resistor
Channel-Gain queue
The channel-gain queue feature allows you to configure a list of channels, modes, and gains for each scan. The settings are stored in a channel-gain queue list that is written to local memory on the device.
The channel-gain queue list contains one or more channel numbers, modes, and range settings. You can configure up to 8 elements. The channels can be listed in any order, and can include duplicate channels for sampling at different ranges.
An example of a 4-element list is shown in the table Seite 14.

Carefully match the gain to the expected voltage range on the associated channel or an over range condition may occur. Although this condition does not damage the device, it does produce a useless full-scale reading, and can introduce a long recovery time due to saturation of the input channel.
Analog output
Two 16-bit analog outputs are available at AOUT0 and AOUT1.
Each analog output channel has an output range of ±10 V. Throughput is system-dependent.
The D/A is software-paced. Each 16-bit analog output ( AOUT0 and AOUT1 ) can be updated simultaneously at rates from 1000 S/s to 5000 S/s. This is the typical throughput when the device and host are both hard-wired to the same local network. Typical throughput is not guaranteed if a wireless connection is involved or data is sent over the Internet.
External clock I/O
The RedLab E-1608 provides one external clock input ( AICKI ) and one clock output ( AICKO ) for analog inputs.
You can connect an external clock signal to
AICKI .
When using the internal clock,
AICKO outputs the ADC scan clock.
Digital I/O
You can connect up to eight digital I/O lines to DIO0 through DIO7 . Each digital channel is individually configurable for input or output. The digital I/O terminals can detect the state of any TTL-level input and offer . advanced BiCMOS output.
Refer to the schematic shown in Figure 5.
Figure 5. Schematic showing switch detection by digital channel DIO0
If you set the switch to the +5 V input, DIO0 reads TRUE (1). If you move the switch to GND, DIO0 reads
FALSE (0).
Pull-up/down configuration
Unconnected inputs are pulled high by default to 5 V through 47 kΩ resistors via jumper W3 on the circuit

Caution! The discharge of static electricity can damage some electronic components. Before touching the board, ground yourself using a wrist strap or touch the computer chassis or other grounded object to eliminate any stored static charge.
Pull-down
Figure 7. W3 jumper configurations
Trigger input
The TRIG terminal is an external digital trigger input. The trigger mode is software selectable for edge or level sensitive.
Edge sensitive mode is configurable for rising or falling edge.
Level sensitive mode is configurable for high or low level.
The default setting at power up is edge sensitive, rising edge.
Counter input
The CTR terminal is a 32-bit event counter that can accept frequency inputs up to 10 MHz. The internal counter increments when the TTL levels transition from low to high.
Power output
The +VO terminal can output up to 10 mA maximum. You can use this terminal to supply power to external devices or circuitry.
Ground
The analog ground ( AGND ) terminals provide a common ground for all analog channels.
15
RedLab E-1608 User's Guide Functional Details
The digital ground ( GND ) terminals provide a common ground for the digital, counter, timer, and clock channels and the power terminal.

On when there is a valid host connection and blinks when a command is received or an AInScan is running.
Left (green): Link/activity indicator; on when there is a valid Ethernet link and blinks when network activity is detected.
Right (yellow): Speed indicator; on for 100 Mbps, off for 10 Mbps or no link.
Used to reset the network configuration settings to the factory default values.
Press the button when applying power to the device and continue to hold for
4 seconds; the device LEDs stay off, and then both the Power and Activity LEDs blink once indicating that the settings have been restored to the defaults.
Release the button so the device continues startup with the default settings. If the button is released before the two LEDs blink, the settings are not affected and the device starts up normally.
