git measComp supports Ethernet and USB I/O modules from Measurement Computing.

Models supported in measComp include:

• The USB-CTR08. This device is an 8-channel counter/timer module. The driver supports the EPICS scaler record with 8 32-bit counters. Counter 0 can be used as a preset counter that controls the other 7 counters, the same as the Joerger VSC or the SIS3820. The driver also supports using the USB-CTR08 in multi-channel scaler (MCS) mode like the SIS3820, with internal or external channel advance and dwell times as short as 250 ns. The device also contains 4 programmable pulse generators, and 8 digital I/O bits, which are supported with standard EPICS records.
• The USB-1208LS. analog I/O module. This device contains 8 single-ended/4 differential 12-bit analog inputs, 2 10-bit analog outputs, a 32-bit counter input, and 16 binary input/outputs. The driver supports simple analog I/O, binary I/O, and a counter input.
• The USB-1208FS. analog I/O module. This device contains 8 single-ended/4 differential 12-bit analog inputs, 2 12-bit analog outputs, a 32-bit counter input, and 16 binary input/outputs. The driver supports simple analog I/O, binary I/O, and a counter input.
• The USB-1608GX-2AO. analog I/O module. This device contains 16 single-ended/8 differential 16-bit analog inputs, 2 16-bit analog outputs, and 8 binary input/outputs. The analog inputs and outputs can each be run at 500 kHz. The driver supports simple analog I/O, 2 waveform generators using the analog outputs, an 8 or 16 channel waveform digitizer using the analog inputs, binary I/O, 2 counter inputs, and a pulse generator.
• The USB-1608G. analog I/O module. This device contains 16 single-ended/8 differential 16-bit analog inputs, and 8 binary input/outputs. The analog inputs can be run at 250 kHz. The driver supports simple analog I/O, an 8 or 16 channel waveform digitizer using the analog inputs, binary I/O, 2 counter inputs, and a pulse generator.
• The E-1608 analog I/O module. This is an Ethernet device with 8 single-ended/4 differential 16-bit analog inputs, 2 16-bit analog outputs, and 8 binary input/outputs. The analog inputs can be run at 250 kHz. The driver supports simple analog I/O, an 4 or 8 channel waveform digitizer using the analog inputs, binary I/O, and 1 counter input.
• The USB-231 analog I/O module. This device contains 8 single-ended/4 differential 16-bit analog inputs, 2 16-bit analog outputs, a 32-bit counter input, and 8 binary input/outputs. The driver supports simple analog I/O, binary I/O, and a counter input.
• The USB-2408-2AO analog I/O module. This device contains 16 single-ended/8 differential 24-bit analog inputs, 2 16-bit analog outputs, and 8 binary input/outputs. The analog inputs can measure either temperature or voltage. Thermocouple types B, E, J, K, N, R, S and T are supported. The analog inputs and outputs can each be run at 1 kHz. The driver supports simple analog I/O, 2 waveform generators using the analog outputs, an 8 or 16 channel waveform digitizer using the analog inputs, binary I/O, and 2 counter inputs.
• The E-TC thermocouple module. This is an Ethernet device with 8 24-bit thermopouple inputs, a 32-bit counter and 8 binary input/outputs. The driver supports temperature measurements at up to 4 Hz, binary I/O, and 1 counter input.
• The TC-32. thermocouple module. This device contains 32 thermocouple inputs, 8 binary inputs and 32 binary outputs. Thermocouple types B, E, J, K, N, R, S and T are supported. The binary outputs can be controlled by the driver or can be configured to be an alarm output controlled by the corresponding thermocouple input. USB and Ethernet interfaces are both provided, and either can be used.
• The USB-4303. This device is a counter/timer module. It contains 2 9513 counter/timer chips, each of which contains 5 16-bit counter/timer units. The driver supports independent control of each counter/timer unit, but it also supports the EPICS scaler record with 4 32-bit counters, a 16-bit preset timer, and one 16-bit counter. The device also contains 8 binary outputs, 8 binary inputs, which are supported with standard EPICS bi, bo, longin, and longout records. NOTE: This module is obsolete and is no longer be available. Use the USB-CTR08 instead.
• LThe E-DIO24 digital I/O module. This device contains 24 digital I/O lines and 1 counter.

Release notes

Required Modules

The required versions of each of the above modules for a specific release of measComp can be determined from the measComp/configure/RELEASE file.

Installation and Building

After obtaining a copy of the distribution, it must be installed and built for use at your site. These steps only need to be performed once for the site (unless versions of the module running under different releases of EPICS and/or the other required modules are needed).

1. Create an installation directory for the module, usually this will end with
   
   .../support/
   
2. Place the distribution file in this directory. Then issue the commands (Unix style)

   gunzip measCompRX-Y.tar.gz
   
   tar xvf measCompRX-Y.tar
   

   where X-Y is the release.
3. This creates a <top> application.
   

   .../support/measCompRX-Y
   

4. Edit the configure/RELEASE file and set the paths to your installation of EPICS base and to your versions of other required support modules.
5. Run gnumake in the top level directory and check for any compilation errors.
6. Please email Mark Rivers so that a record can be kept of which sites are using this software.
