Page 7: Section 3 - Installation And Interconnections
Note that the instrument must always be situated in such a way as to enable adequate air circulation about the unit. If a transducer was supplied with the CCD104 a suitable cable may have been included. Transducer socket Pinout - 15 Way 'D' Type (x4) -
Page 8: Usb Connector - Usb Type-C
USB Connector – USB Type-C The connector supports USB-C 2.0 cables without the SuperSpeed pairs. Therefore connecting a fully featured USB-C 3.1 cable will not provide SuperSpeed functionality, although the cable will still work as per the USB 2.0 specification. USB is provided for legacy serial data comms and debugging purposes. -
Page 9: Section 4 - Front Panel Operation
Section 4 - Front Panel Operation Introduction The front panel consists of a 480x272 TFT LCD colour display with a capacitive touch membrane consisting of 11 ‘switches’ and a ‘scroll wheel’. Each switch has legends on it (and in some cases above it) to indicate the function of the switch. Most switches have some commonality between different screens, as detailed below. -
Page 10: Hmi Breakdown
HMI breakdown Here follows a complete breakdown of all screens that appear whilst using the CCD104: (a) Main Screen The main screen shows the currently enabled input data (with range, full-scale and calibration applied). Each channel can be assigned a label (‘Chx’ above) and a units string. -

(b) Main Menu Screen The Main Menu screen provides access to the configuration sections of the CCD104. Switch Functions: Func Go back to Main screen No function ◄ No function ► Move menu selection up and down ‘Wheel’ No function... -
Page 12: (C) Inputs Screen
(c) Inputs Screen The Inputs screen contains all user configuration items for each of the input channels. The screen shows the items for one channel at a time and the Title on the from top row of the screen indicates which channel’s information is selected. The ‘Chx’... -
Page 13: (D) Setpoint Screen
(d) Setpoint Screen The setpoint screen allows for changing of the initial setpoint settings that the unit will use for each channels’ setpoint on power up. As with the Inputs screen above, the screen shows the items for one setpoint channel at a time and the Title on the from top row of the screen indicates which channel’s information is selected. -
Page 14: (E) Ethernet Screen
The Communications screen allows you to edit the various Ethernet settings for remote communications with the CCD104. For Ethernet comms, the IP address and subnet mask can be changed. Although any number can be cycled to during edit mode, the CCD104 will cap at 255. Switch Functions: Func... -
Page 15: (F) Filtering Screen
Filtering Screen This screen allows the user to modify the band and buffer size of the adaptive filter. The filter only applies to the display and comms output readings. The band is represented as a percentage of FS and can be set between 0.00% (OFF) and 1.00% and also to ON. -
Page 16: (G) Relay Screen
(g) Relay screen The Relay screen allows you to set the trip point for when the relay switches and also set the source channel that is used to check if the trip point has been reached. The relay also contains some hysteresis to stop the relay ‘chattering’. This is configurable from this screen as well and is represented as a percentage of full scale of the source channel, with limits of 0.0% (i.e. -
Page 17: (H) Factory Defaults Confirm Screen
(h) Factory Defaults Confirm Screen This screen appears when selecting the Factory Default item from the Configuration Menu screen to provide an extra user interaction check before performing the default. If actioned, all settings are returned to their factory defaults (see Table 2 in Appendix B). -
Page 18: Section 5 - Webserver Operation
Section 5 - Webserver Operation The webserver is an easy way for the user to change the device settings and to access channel data. The webserver can be accessed by entering the device IP Address into a browser URL bar. The webserver is divided into multiple sections (Pages) that control different aspects of the device. -
Page 19: Live Data' Page
‘Live Data’ Page The main section when the page first loads up is the ‘Live Data’ page, this page allows the user to monitor the current live data of each channel, as well as channel specific setpoint control. The ‘Live Data’ page allows the user to rezero each channel individually by using the zero buttons underneath the channel label. -
Page 20: Control Cfg' Page
‘Control cfg’ page The control configuration page is made of multiple sections that allow the user to change various settings of the device itself. (a) ‘Communication’ section The communication section allows the user to change the device IP Address and Subnet mask. -
Page 21: (B) 'Filtering' Page
(b) ‘Filtering’ page The filtering page is a way of controlling the active filtering facility of the device to help reduce noise in the data. · Band relates to the filtering limits. The setting is percentage of fullscale and can be set between 0.01% and 1.00%. -
Page 22: Linearisation' Page
‘Linearisation’ page The linearisation page is a way for the user to apply a linear cal to the data to correct any non-linearity’s that may exist in a connected transducer. The user can store up to 11 points. The Links at the top of the page allow the user to switch between each channels linearisation data. -

Page 25: (B) Output Current Readings Repeatedly - 'Rp
Auto Close Setpoint modes bit table This number is mainly included for use with Chell’s DisplayX front-end software and is mainly useful when outputting repeated readings, where it effectively provides a constant update of the current mode of each setpoint. -
Page 26: (D) Setpoint Mode - 'Spm
SP2 VALUE: <setpoint 2 value> SP3 VALUE: <setpoint 3 value> SP4 VALUE: <setpoint 4 value> (d) Setpoint mode – ‘spm’ This command sets the mode for a particular setpoint. The command takes two parameters – the first is the setpoint to set and the second is a number between 0 & 2, identifying the mode, as follows: 0 = Auto mode 1 = Open mode... -

Page 28: Comms Commands
Comms commands (a) Ethernet IP address – ‘eip’ This command changes the IP address used to communicate over TCP/IP comms. The parameter should be entered as a standard 4 octet IP address. e.g. 192.168.1.180. The max octet value is 255. If a greater value is entered, that value will be capped to 255. Once the CCD has responded to the command, it will display the following and should restart. -
Page 29: (B) Input Channel Units String - 'Uiu
(b) Input channel units string – ‘uiu’ Each input channel has an associated free-form text field that can be used to identify the units being used on the channel. This command is used to set this and it takes two parameters –... -
Page 30: Filtering Commands
Filtering commands (a) Filter band – ‘flb’ This command is used to set the point at which the adaptive filtering kicks in. It takes one parameter which is the percentage of full scale of the input. Valid values are between 0.01% and 1.00%. -
Page 31: (C) Relay Hysteresis - 'Rlh
(c) Relay hysteresis – ‘rlh’ This command configures the hysteresis setting of the relay. It takes one parameter which is the percentage hysteresis, represented as a percentage of full scale of the source channel, with limits of 0.0% (i.e. no hysteresis) to 10.0%. The current hysteresis setting can be retrieved using the query ‘rlh?’. -
Page 32: Section 7 - Principles
If the device outputs 5V, the CMD100 will show 50, and so on. Analogue Outputs There are a total of 8 analogue outputs on the CCD104. There are four voltage outputs for setpoint control, each with their own setup parameters (see next section) and four voltage outputs that simply retransmit the main input voltage (before it is manipulated by the ADC and microprocessor). -
Page 33: Setpoint Control
The percentage is set via the ‘▲’ & ‘▼’ switches and the external value comes from one of the other input channels. Setpoints are volatile, in that when power is removed from the CCD104, the current setting of each setpoint value and mode is NOT remembered. However, there are some initial... -
Page 34: Adaptive Filtering
Adaptive Filtering The CCD104 includes an adaptive averaging filter on the display and comms readings output to aid in ‘smoothing out’ unwanted ‘noise’ on the displayed readings. The filter is not channel specific – if enabled it filters all readings for all displayed channels. -
Page 35: Section 8 - Service And Calibration
Section 8 - Service and Calibration Service There are no user serviceable parts inside the instruments. Should any difficulties be encountered in the use of the CCD104, it is recommended that you contact Chell Instruments Ltd for advice and instructions. Calibration There is no user calibration for the CCD104. -
