CFLink and Special Characters?#@;

[Nahshon Williams]

So I am currently troubleshooting RS485 on the Mod 4.

I have a PDU that I have tested with another automation system and they both work well.

Tried controlling the same PDU with the following command in Hercules:

$F2$11$F3TCOMSPW$F4M2|P03:##switch 3,0$0DF5$F5 (hercules requires the double hash/pound symbol)

Unfortunately the CF log in system commander  only sees this:

\xF2\x11\xF3RCOMSPW\xF4M2|P03\xF5\xF5

The PDU does not respond at all. 

Am I missing anything?

RCOMSPW is the reply to tell you that the data was sent (all commands starting with 'R' are replies), it does not include the actual data sent to reduce unnecessary traffic.

Your hercules command is missing a dollar sign in front of the second last \xF5

As I have been having difficulties getting the CF hardware to talk to the loxone RS485 module I am now testing  connectivity between ONLY CF hardware ports using identical port setting.

I have three COM modules on the Mod4

Two ports configured as RS485 @ 115200 BAUD 1 Stop No Parity.

In theory I should see messages sent from Module 3 port 1 to Module 2 port 3 come up on the CF link logs. 

It should be clear when a message is sent and received on the CF log (instantaneously)

In similar fashion TCP messages sent to either port  using the CFLINK  protocol should be mirrored in the log  as received by the destination port right?

Problem is the log only shows the received messaged from the TCP or the sent messages from the "COM Port Testing" field in System Commander, I cannot see any RECEIVED messages appearing on the CF log.

The wiring is as attached I have grounded pin 2 and 5  as per the CF pin out for Half duplex RS485 (also attached)

Am I still missing smth? (if this was RS232 I would cross the Tx Rx lines but this is bus based so parallel connections right?)

Does port numbering change with RS485? 

As one whole row of pins is used in both cases?

RS485 can only be on ports 1 and 3 as per the docs here:

Hi Nahshon,

I have setup a similar system and it works without any problem. Below are my settings:

1: Communication : UDP , port 10207

2. COM4 module on Slot1 and Slot2 of DIN-MOD4

            1. COM4 Slot1 - P01, RS485 half duplex, 115200-8-N-1-0

            2. COM4 Slot2 - P01, RS485 half duplex, 115200-8-N-1-0

3. LANBridge firmware version v0.1.7

4. DIN-MOD4 firmware version v1.14.5

5. System Commander version 1.1.816

I have successfully transmit data from P01 of Slot1 to P01 of Slot2. Attached is the log from system commander.

Simple Wiring:

If the above demo still doesn't work for you, please do the following in the Test Command Area
of System Commander:

Repeat the same steps for Module 2. The reply string should be v0.0.7 which is the latest firmware for COM4.

Let me know if this helps.
