DeviceMaster ® PRO. The DeviceMaster PRO network serial device servers designed for network-enabling serial communications devices. When used with the included NS-Link™ driver software and a host PC, the DeviceMaster PRO enables placement of COM or TTY ports anywhere on an Ethernet network or across the Internet. Although any USB to RS-232 cable should work with the appropriate drivers, there is a better chance of success using the USB to RS-232 cables sold by Campbell Scientific. There are several options for data loggers that don’t have an RS-232 port but have a CSI/O port: Use the SC-USB connector/interface instead of the SC32B. Your mobile device while away from your facility. Your PAC Display HMI on a PC in one part of the factory needs to access data from a SNAP PAC controller in another part. You’re using the mobile apps Opto iPAC or Opto aPAC to commission your system. You need to share data between your SNAP PAC System and devices from another. To verify that your driver is working, you should see a difference in the following pictures after plugging the CH340 to a USB port. To check that the CH340 enumerates to a COM port, you can open the device manager. You can click the Start or ⊞ (Windows) button and type 'device manager to quickly search for the application. An isolation device allows data and power to transfer between the high-voltage and low-voltage units, while preventing any hazardous DC or uncontrolled transient current flowing from the grid. Isolation robustness and higher power density is realized by integrating the isolator with a key power component: the integrated high-speed isolated gate.

USB-OPTO-RLY88,8optically Isolated Inputs, 8 Relay Outputs
Technical Documentation

The USB-OPTO-RLY88 provides eight optically isolated inputs and eight volt free contact relay outputs with a currentrating of up to 1Amp each. It is powered from any standard USB bus and has anexceptionally low maximum current consumption of approx. 90mA with allrelays on. The relays are SPCO (Single Pole Change Over) types. The normallyopen, normally closed and common pins are all available on the screw terminals.


USB -Standard type B receptacle.
Inputs -Absolute Max. 30v DC, Operational 4.5v to 27v DC
Outputs -Relay Contacts, see power graph below

LED Indication
Each of theeight input channels has a Green LED to indicate the inputstatus.
Each relay output has a Red LED to indicate the relay status.
Also power status is indicated with an LED driven from the USB supply.
Relay power rating
If the contact load voltage and current of the relay are in the region enclosedby the solid and dotted lines in the
figurebelow, the relay can perform stable switching operation. If the relay is used ata voltage or current exceedingthis region,the life of the contacts may be significantly shortened.

First Step - Get The Drivers
Before connecting the USB-OPTO-RLY88 module, you should downloadthe driver and unzip it to a temporary folder. Now connect the USB-OPTO-RLY88module and navigate windows to the temporary folder and install the driver.The USB-OPTO-RLY88 will now appear as a COM port.

Which COM port?
After installing the drivers, and plugging in the USB-OPTO-RLY88 module to aspare USB port, you will want to know which COM port it has been assigned to.This will vary from system to system depending on how many COM ports youcurrently have installed. To find out where it is, right click on your 'MyComputer' desktop icon and select 'Properties->Hardware->DeviceManager'. Now scroll down and open the 'Ports (COM & LPT)'tab. You should see the USB serial port listed - COM5 in the example below. Ifyou want to change the COM port number - just right click on it, selectproperties, select advanced and select the COM port number from the availablelist. The COM port default will probably be set up for 9600 baud, 8 data bits,no parity and one stop bits, but what ever it is just ignore it. These settingsare not actually used because we have a full 12Mbits USB connection right intothe heart of the processor.

The USB-OPTO-RLY88 operates with an easy to use command set as described in the tablebelow. Most commands are only a single byte and if applicable the USB-OPTO-RLY88will automaticallysend its response. The only exception to this being the 'Set relaystates' command which requires and additional desired states byte to besent immediately after the command byte.



1711Returns channel 1 state as 1 byte, where 255 indicates input is powered and 0 indicates it is not.
1812Returns channel 2 state as 1 byte, where 255 indicates input is powered and 0 indicates it is not.
1913Returns channel 3 state as 1 byte, where 255 indicates input is powered and 0 indicates it is not.
2014Returns channel 4 state as 1 byte, where 255 indicates input is powered and 0 indicates it is not.
2115Returns channel 5 state as 1 byte, where 255 indicates input is powered and 0 indicates it is not.
2216Returns channel 6 state as 1 byte, where 255 indicates input is powered and 0 indicates it is not.
2317Returns channel 7 state as 1 byte, where 255 indicates input is powered and 0 indicates it is not.
2418Returns channel 8 state as 1 byte, where 255 indicates input is powered and 0 indicates it is not.
2519 Sends 1 byte back. Individual bits indicate input status of each channel, a 1 indicating powered input
261ASends 8 bytes back. First byte is channel 1 as per command 0x11 above. Last byte is channel 8.
5638Returns 8 ASCII characters. This is an 8-digit globally unique identifier. No two modules will share this.
905AGet software version - returns 2 bytes, the first being the Module ID which is 12, followed by the software version

Get relay states - sends a single byte back to the controller, bit high meaning the corresponding relay is powered

Abacus Optical Probe USB Driver Installation for Windows

Drivers opto port devices gigabit
In most cases, plugging in the Abacus Optical Probe in to the USB port of the computer will use the Windows Update feature to automatically retrieve the drivers and install them for use with the probe for Windows 10 and other Windows operating systems.
Then navigate to Device Manager and Ports and check for an entry for “USB Serial Port”. If installed correctly the Drive Manufacturer (in the Properties, Driver tab) will show up as FTDI (the manufacturer of the USB chip and driver for the Probe) and the Probe can be used with the listed COM port. It may be possible to change the COM port assignment by accessing Properties, Port Settings tab, Advanced button, and COM Port Number entry, if a lower COM port number is desired for software compatibility.
Note, the process may take some time, require re-plugging the probe, and require internet access. If the device does not show up in Device Manager or is shown with a trouble indicator, it may be necessary to enable the Windows Update capability, or due to security restrictions choose the manual installation below.
