FBL2360 TTL Serial or RS485

I am having difficulty communicating with an FBL2360 via 3.3V TTL Serial from a microcontroller.

My current connections are from:
TTL Tx (microchip) -> Pin 11 (TTL RxD)
TTL Rx (microchip) <- Pin 23 (TTL TxD)
Gnd (microchip) <-> Pin 1 (Gnd)

In other configurations, I can communicate successfully via USB and via RS232 (pins 2,3,5).

My unit is v2.3 and I have firmware version 1.6 installed (4/14/2016).

I have tried typing ^SCRO 3 from the terminal as sugested in ( dev.roboteq.com/dev1/index.php/support/f...ication?limitstart=0 ), with no effect. Also, if I type ~SCRO, the unit returns SCRO=2

I have tried setting the baud rate to be inverted as described in ( dev.roboteq.com/dev1/index.php/support/s...onnecting-to-arduino ), but when I try to set it to 5 using ^RSBR 5, then read it back with ~RSBR, it reports RSBR=4. The same thing happens if I use ^RSBR 9

I have a number of questions:
1) Does the FBL2360 support TTL Serial, or is it RS485? The datasheet mentions 485 support, but then calls out TTL in Table 3. Also, the datasheet calls out pins 11/23 as TTL, whereas Roborun calls them out as RS485A and RS485B respectively. Is this a configuration setting somewhere?

2) Is there another piece of documentation that I'm missing that highlights additional serial commands? For example, RSBR and SCRO are referenced in the forums, but I can't find them in "Advanced Digital Motor Controllers User Manual".

3) I guess, generically, what am I doing wrong?

Thanks, Blake!

Does it support RS485 connections to those pins? Would I need to send any commands to configure the device to use RS485?

Thanks,
BK

Blake can you put that file on the forum please? I also plan to connect an Arduino-based microcontroller (Udoo-X86).

Thanks Blake, i will contact you as soon as the Udoo is released and delivered.
