I2 C/RS485, 5-Port Comm Hub, IQ 2020
Sku: 74150
$131.05
This 5 port I2C/RS485 adapter is used to “expand” the IQ2020 Controller to allow other accessories to plug into the motherboard. If you’re adding on an IQ 2020® Navigator RF Remote, Music System, Luminescence Multi-Colored LED Light, etc., you’ll need this adapter. The 4 port adapter is also available.
Note: Watkins changed from 8-port to 5-port. The 8-Port was discontinued and replaced with the 5-Port. They used the same part #74150.
This part can be found on
many Hot Spring, Limelight, Hot Spot, Hot Spring pre 89, Tiger River models from 1997 to 2023
