DB9 Y Splitter Adapter Cable

DB9-DB9/DB9 - Y-Splitter (1x Male & 2x Female)

Need to split your CAN bus?

This low cost DB9 (D-sub 9) Y-splitter cable lets you easily split a single CAN bus DB9 connector into two connectors. This is achieved via the quality overmolded male-to-female/female DB9 connectors.

The DB9-DB9/DB9 adapter is ideal for connecting multiple CAN devices to a single port - or e.g. daisy chaining CAN modules.

About the DB9 Y-splitter

The DB9 Y-splitter lets you easily extend and branch out your CAN bus to e.g. add additional CAN nodes.

The adapter is e.g. useful if you need to daisy chain multiple modules together - or provide access for multiple devices through a single CAN bus port.

Example: Dual CAN telematics

The DB9-Y-splitter is e.g. often used in J1939 use cases to let you log data via both Channel 1 and 2 of a CANedge - while at the same time connecting an external module like the CANmod.gps, CANmod.temp or CANmod.input.

Below are some examples where a DB9 Y-splitter can be useful:

Daisy Chain CANmod Temperature Modules

Daisy chain CANmod.temp

Need to log data from multiple CANmod.temp modules?

The DB9 Y-splitter is useful if you need to combine multiple CANmod.temp modules in order to create a CAN bus with e.g. 20 thermocouple channels.

Connect two devices in one port

Need to access a port with multiple devices?

Sometimes you need to connect two devices to e.g. a car OBD2 port. With a DB9-Y-splitter you can e.g. connect your CAN logger - while leaving open a DB9 connector for use by e.g. a diagnostics tool or e.g. a GPS-2-CAN module.

Connect Multiple CAN Bus Devices

No, in principle you can combine as many as you want. Further, you can combine them with our DB9 CAN bus extender cables for building larger CAN bus systems if needed.
