Is this motor a Century Vgreen 165?
If so the Vgreen 165 doesn’t support the Jandy RS485 protocol out of the box, but if you have a computer and a USB to RS485 adapter you can re-write one of the motor’s configuration variables to enable the Jandy Protocol on the pump.
Once enabled, the pump will show up as a Jandy Epump to the Aqualink system.
For the details see this thread:

Yes, it is the 165 model. I also have a USB to RS485 and will give it a go.
Thank you, sir!
Well, the programming seemed to go well. I received all the correct HEX replies. However, my OneTouch controller doesn't seem to have any effect. I believe I programmed the OT correctly for the ePump. I have it set up as an AUX Pump, but I get no response when I select Speed1-8.
Any suggestions?

So the motor responded to Jandy commands okay and the motor ran okay?
Are you trying to set up pump address 1 as that’s the default the motor Dip switches are set for?
Also, do you have continuous AC power to the pump, or do you have it switched through a relay? It should have constant power.

I haven’t ever set up a VSP using the one touch interface panel, @HermanTX, @PoolGate, @1poolman1 might have some ideas using that interface.
In general you have to activate the VSP pump corresponding to the pumps address, generally 1, usually set it up as the filtration pump, and set up the speeds for each of the 8 speeds with speed 1 (Pool) being associated with the filter pump.
Then when you turn the filter pump function the pump will run.
Not sure quite how it works as an auxiliary pump?
Is this your main filtration pump, or is it really an auxiliary pump. There is more on setting up VSP pumps here:

But most of this talks about setting the pump up through the web interface.

When I followed the directions you created, I got all the correct HEX responses and the VSP came on for about a minute. So, it seemed to confirm, as you directed, that the VSP is responding to the Jandy protocol that would typically come from my Aqualink RS4 OneTouch. This VSP is not my main filter pump, it is a pump for a sheer descent waterfall. Since I disconnected the comm cable to the USBto485 (to program the Century VSP) and re-connected the 4-wire to the Aqualink RS4 controller, I think my wiring is correct in both the VSP and the Aqualink RS4 controller (see pics). For the 4-wire to the VSP I am using the second red block and not the main red block that is wired to the OneTouch panel in my house (not sure if this is 100% correct way). Currently, when I try to set the VSP to any of the Speed1-8 via OT it does nothing. There doesn't seem to be an acknowledgement from the VSP that I think the OT (Aqualink RS4 controller) is expecting.I haven’t ever set up a VSP using the one touch interface panel, @HermanTX, @PoolGate, @1poolman1 might have some ideas using that interface.

I do not have a web interface or the wireless iQ module.

Okay, good, your pump responds to Jandy commands so it looks like an Epump. Those Hex commands are sent to pump address 1 so I’ll assume the pump is still on address 1.
Is your main pump also a VSP, or is that a single speed pump? I’ll assume your main pump is a VSP also so it will be set up as the filtration pump, and associated with Epump 1 likely.
The version T.2 RS controller supports up to four VSP pumps on addresses 1 through 4 and they will show up as Epump1 through Epump4.
On the controller you have to set up which pump you intend to use (1 through 4) and you have to set the corresponding DIP switches on the pump to that address.
Which Epump address are you trying to set up as the pump is set for address 1 by default unless you changed it.
If you set up the second pump as an aux pump it will be associated with pump address 2, and you will have to change the pump DIP switches to off, off, on, off, on, where sw1 is listed first and sw5 is last.
Once you have the address set you should should be able to select VSP2 speed 1 from the equipment list and turn it on. The status screen should show Epump 2 online.
If the pump isn’t showing up then you likely haven’t set the DIP switches on the pump to the correct address.
Please provide a bit more information about you first pump (vsp or not) and also the Epump address you set up as the aux pump.

hmm....my main filter pump is single speed and not set up for VSP so, I set the Waterfall up as an AUX pump on Pump1 as the pics show for SW 3 & 4. So, that could be a problem if the Aqualink RS4 thinks the AUX Pump cannot be addressed as Pump1.
UPDATE: It may be a flaw with the Aqualink T2.g firmware, but I was able to get the Waterfall VSP going by setting it as Filtration under Pump1 instead of as a AUX Pump. When set in this manner the OT labels it as Pool. However, after that, I was able to change it back to an AUX Pump under Pump1.
Weird.

Great!, That is weird that it wanted to be filtration, but as you say you changed it back to aux and it’s working now.
There are some quirks with the Aqualink system, but that’s the first I heard of that one. But I bet 99% of the installations use pump 1 as the main filtration pump, so your setup doesn’t come up much.
Glad you got it working.

Another UPDATE: You weren't lying about the Aqualink being quirky. After a few weeks of my Waterfall "ePump" VSP working as AUX Pump1, it suddenly just stopped responding to the Speed requests at the OT keypad. After an hour of programming and re-programming via the OT I decided to just change the DIP settings at the VSP from Pump1 to Pump2. I then programmed the OT accordingly and it seemed to work the first try. Fingers crossed. If this setting holds, I'll assume the Aqualink just doesn't like Pump1 on AUX.
