Page 4: Introduction
You can find SNAPlink documentation, including this User Guide and the Quick Start guide packaged with your device, online at: http://info.synapse-wireless.com/SNAPlinkintro You can also download the EasySet software from that site, allowing you even more configuration and control over your SNAPlink devices. -
Page 5: Getting Started
Getting Started SNAPlink devices provide many configuration options for compatibility with nearly any RS-232, RS-422, or RS-485 device. This section provides instructions to get your devices up and running in using the DIP switches inside the devices, or the EasySet software. Powering the SNAPlink You can power your SNAPlink units via the power terminal blocks, or through its USB connection. -
Page 6: Understanding Multipoint Mode
Understanding Multipoint Mode In multipoint mode, one of the SNAPlink devices is designated the master and one or more other devices can be configured as slaves. In this configuration, messages sent by the master will be sent to all slave devices, while messages sent by the slaves will be received only by the master unit. -
Page 7: Defaulting To Broadcast State
NOTE: If you have an exceptionally noisy RF environment, you may find that one or both of the devices have LED A flashing amber rather than green. If this occurs, you should consider switching your devices to a different SNAP channel, which would use a different radio frequency. You can make this change using the EasySet software or using the DIP switches inside the SNAPlink device. -

USB connection as its serial input source, you will also need these drivers installed on the computer sending data. Be sure to disconnect any Synapse USB devices from your computer as the installer runs. (The installer will prompt you with a reminder for this when it is appropriate.) -
Page 10: Using Easyset
Using EasySet Launch EasySet by selecting EasySet from the Windows Start menu. EasySet will start up and present this window. You will see four icons in the tool bar across the top of the window. Most of these are inactive (grayed out) until EasySet is connected with a SNAPlink adapter. -
Page 11: Selecting Basic Communications Settings
When EasySet finds a Synapse device, click the Connect button. If it failed to find the correct device type, press the Scan button ( ) to the right of the port identifier. This will instruct EasySet to continue the scan. - Page 12 The Firmware field displays the name of the script loaded into your SNAPlink device. Firmware This will be SNAP_Link unless Synapse Customer Support has provided an alternate. The Network ID can be thought of as a logical channel. This 16-bit integer may be assigned any hexadecimal value from 0x0001 through 0xFFFE.
- Page 13 SNAPlink adapters contain two UART (Universal Asynchronous Receiver/Transmitter) connections, one for the USB port and one for the serial communications (RS-232 or RS- 485/422) port. This setting indicates which port is connected to your serial device and where the serial data should be transmitted or received. The factory default is to send all serial data through either the RS-232 DE9 or RS-485/422 terminal block and NOT through the USB cable.
- Page 14 Mesh Tab The Mesh tab allows you to tune your network to accommodate unusual environments, such as when you need intermediate nodes to forward your data in case of great distances or interference. Typically one of the two preconfigured options, "Mesh" or "No Mesh" will be appropriate for your application. Mesh Routing Settings SNAP-based nodes in a complex environment will constantly update their communication routes to provide the best path for getting all...
- Page 15 No Mesh In contrast, the No Mesh configuration tells a device to not aid other devices when they are trying to establish routes. With the No Mesh configuration, each node is still perfectly happy to make use of other willing participants in the mesh network, but will not volunteer to forward messages for other nodes.
- Page 16 Mesh Routing Initial Hop Limit The Mesh Routing Initial Hop Limit specifies how close a device expects its target device to be when it starts performing a route discovery. Setting this value to zero indicates that the node expects its target node to be within direct radio range, which means any other nodes in the vicinity who might overhear the route request will not attempt to assist with the initial route discovery request, even if they do not have Mesh Override enabled.
- Page 17 Client 1 and Client 2 to On for the Multi-cast Forwarded Groups should help make sure all transmissions are received by Client3. (Note that return messages from Client3 to the Master will also require that Client1 and Client2 have Mesh Override disabled.) In a point-to-multipoint environment where the master device can directly communicate reliably with all of the slaves, the default value of 0 is appropriate.
- Page 18 If you set Buffering Threshold to a large number, then larger, more efficient packets will be sent, but with greater latency. At higher bps rates setting this value too high can result in dropped characters, as the SNAPlink device may receive more characters than it can fit in a packet before it has an opportunity to realize that the packet is full.
- Page 19 This field specifies the number of seconds between pings. The default value is 3 seconds. Advanced Tab The Advanced tab contains a single checkbox labelled Button Lockout. When checked, the MODE button on the front of the SNAPlink adapter will be disabled. This means the pairing state or point-to-multipoint state of the device cannot be modified using the button.

Page 20: Configuring Your Adapter Using Dip Switches
Configuring Your Adapter Using DIP Switches If you do not have access to a computer running EasySet, you can configure some communication parameters using the DIP switches located inside the unit. Changing DIP switch settings will override the default parameters, or parameters previously configured using the EasySet software. - Page 21 Bps Rate Switch 2 Switch 3 Switch 4 19,200 38,400 57,600 115,200 Switches 5, 6, 7, and 8 collectively control the SNAP radio channel, as follows. SNAP Channel Switch 5 Switch 6 Switch 7 Switch 8 Because flow control, the bps rate, and the SNAP radio channel can all be controlled by either the DIP switches or the EasySet software, SNAPlink devices work on a "most recent instructions"...
- Page 22 NOTE: Channel 15 is not available for transmitting data for SL485-003, SL485-004, SL232-003, and SL232- 004 devices, however it can receive data. It is conceivable that in an environment of mixed first- and second- generation SNAPlinks, where first-generation devices are permitted to use channel 15, second-generation devices could be configured as multicast slaves that could hear and act on instructions from the master without being able to send data back.

Page 24: Can't Find A Master
When operating normally, a SNAPlink master will slowly blink LED A, alternating between green and amber. If it detects the presence of another master on the same channel, it will then alternate the colors between red and amber. Can’t Find a Master If a SNAPlink device is unable to pair with a master, there may be several possible problems: Ensure there are not multiple masters on the network by observing LED A on your master device as described above. -
