Installing the E-1608-OEM
UnpackingAs 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.

Downloading the software
Refer to the E-1608-OEM product page on the Measurement Computing website for information about the
supported software you can download.
Install the software before you install the hardware
The driver needed to run the device is installed when you install the software. Therefore, you need to install thesoftware package you plan to use before you install the hardware.

Connecting the external power adapter
Power to the E-1608-OEM is provided with the 5 V external power adapter (PS-5V1AEPS). Connect theadapter cord to the power connector on the E-1608-OEM device, and plug the AC adapter into an electricaloutlet.
The Power LED turns on when 5 V power is supplied to the E-1608-OEM. 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 on page 12 for the location of the Power LED.

Connecting the E-1608-OEM
The E-1608-OEM requires a TCP/IP and UDP connection to a network or computer. Use the standard Ethernet
cable provided to connect the E-1608-OEM to a 10Base-T- or 100Base-TX compatible Ethernet port, hub, or
switch.
When connecting the E-1608-OEM 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 thelower left of the Ethernet connector turns on when there is a valid Ethernet link, and blinks when network
activity is detected.
Once the E-1608-OEM 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 thedefault configuration by following the instructions in the Restoring factory default network settings on page 10.
Once a connection is established and you can communicate to the device, you can change the configuration forother network scenarios.

8E-1608-OEM User's Guide

Installing the E-1608-OEM

Configuring network settings
The following E-1608-OEM network settings are software-selectable. Only one user at a time can connect tothe E-1608-OEM to configure network options on the device. For typical local networks, the default settings arerecommended.

Address mode settings
The address mode setting determines whether the default IP parameters (IPv4 address, subnet mask, andgateway) are assigned to the E-1608-OEM 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 E-1608OEM.
If the connected network does not have a DHCP server, the address stored in the default IP address is assigned
to the E-1608-OEM.
If the E-1608-OEM 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 E-1608-OEM and the PC to which it isconnected
DHCP Only
Enables configuration by a DHCP server if one is available. The E-1608-OEM is assigned an IP address shortly
after it is powered up and attached to the network.
Link Local Only
The E-1608-OEM is assigned a link-local IP address by the Windows PC to which it is connected. A link-local
address is valid only for communications between the E-1608-OEM and the PC to which it is connected.
StaticThe default IPv4 Address is manually configured on the E-1608-OEM.

IP address settings
The default settings of the following IP address are assigned to the E-1608-OEM 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 E-1608-OEM . The subnet mask determines thenumber 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 E-1608-OEM. The gateway address of the device
that bridges subnets within a network. The default gateway is 192.168.0.1

Connection code
The connection code is 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.

Installing the E-1608-OEM

Setting up the E-1608-OEM for communication across networks
In order to communicate with the E-1608-OEM 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 E-1608-OEM is installed on the host LAN, and the computer is installed on theclient LAN.
Caution! This procedure should only be performed by a network administrator or computer professional.
Incorrect settings can significantly disrupt a network.
1.

2.

3.

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 thedefault address to the address assigned and setting the device network configuration to static.
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)
On the computer connected to the client LAN, manually enter the WAN address of the host router, andspecify the ports that were forwarded to connect to the remote E-1608-OEM.

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 firstand 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 specificvalues 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 on page 12 for the location of this button):
1.
2.
3.
4.

Remove power from the device.
Press and hold the Factory reset button while re-applying power.
Hold the button for at least four seconds until both the Power and Activity LEDs blink, indicating that thesettings have been restored to the factory 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.

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 Measurement Computing Manufacturing Test department performs the initial factory calibration. Contact
Measurement Computing for details about how to return your device and have it calibrated to the factory
specifications. The recommended calibration interval is one year.

Functional Details
Analog input modes
The E-1608-OEM 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 asoftware command. The analog value is converted to digital data and returned to the computer. Repeat thisprocedure 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).

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.

14

E-1608-OEM User's Guide

Functional Details

Leave unused input channels either floating or tied to an AGND connector. Source impedances should be kept
as small as possible to avoid settling time and accuracy errors.
Figure 3 shows DIFF channels 0-3 connected to a ground path resistor.

Figure 3. 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 canconfigure up to 8 elements. The channels can be listed in any order, and can include duplicate channels forsampling at different ranges.
An example of a 4-element list is shown in the table below.

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.
For more information about analog signal connections
For more information about analog input connections, refer to the Guide to Signal Connections (this document
is available on our website at www.mccdaq.com/signals/signals.pdf).

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 connected by15

E-1608-OEM User's Guide

Functional Details

Ethernet to the same local network. Typical throughput is not guaranteed if a wireless connection is involved ordata is sent over the Internet.

External clock I/O
The E-1608-OEM 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 individuallyconfigurable for input or output. The digital I/O connectors can detect the state of any TTL-level input and offer. advanced BiCMOS output.
Refer to the schematic shown in Figure 4.

Figure 4. 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 circuitboard (see Figure 5).

Specification
3.3 V < Vext < 5.9 V: On
Vext < 3.3 V, Vext > 5.9 V: Off (power fault)
On when there is a valid host connection and blinks when a command is received oran AInScan is running.
 Left (green): Link/activity indicator; on when there is a valid Ethernet link andblinks 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 thedevice starts up normally.
