Detect Cable on mAP Lite? Possible typo in supported devices?

[ferferga]

Hello

I’ve used the Detect Cable feature in other Mikrotik devices with success. I’m looking forward purchasing a couple of mAP Liite devices to have this capability in a portable device.

However, from the table shown in the help pages:

From the website the mAP Lite model name is RBmAPL-2nD and mAP is RBmAP2nD. But in the table, a “RBmAP2n” model appears and no product name that matches that appear in the website (neither current or archived). Is that a typo perhaps?

Can somebody confirm me if the mAP Lite works for Cable Detect? Or do I need to go for the mAP?

[holvoetn]

As far as I know RBmAP2n and RBmAP2nD are both the same device.

Map Lite does have cable test function, just tested it (connected via Wifi).

I have to presume that the mAP (and consequently the mAP lite) are loosely similar to the hAP lite, last time I tested this latter I came out with more than a few oddities (JFYI):

cable-test on hap lite, pure madness

The other day cable-test features of Mikrotik/Ros happened to be mentioned here: http://forum.mikrotik.com/t/hap-ax2-poe-port-suddenly-limited-to-100mbps/181713/1 and I remained with the curiosity about what each cable pair line/entry meant (the order they are shown could be either by wire colour/twisted pair or couple of pins on rj45, i.e. 1 and 2, 3 and 6, 4 and 5, 7 and 8 ), so I dig out of the box of things that may come useful one day an old (defective) self-crimped cable some 3 m long, …

[ferferga]

Yeah, that’s why it was strange for me. To be more precise, the RBmAP2n doesn’t exist, since the mAP is RBmAP2nD. This made me guess that RBmAP2n was referring to the lite (although the real name is RBmAPL-2nD), but obviously it was just my guess and not a confirmation.

Since you have a mAP Lite, can you try performing the cabe test using CLI? In my RB5009 I was able to measure cable lengths by having the other end unplugged. However, I don’t see the lengths in your screenshot (even in the “no link” screenshot) and I wonder if it’s a visualization problem with Winbox or somehow there’s also a distinction between devices that can/can not measure the distance (although it’s not mentioned in the docs).

@normis Can you guys fix the model typo in the documentation as well please?

As requested:

First test without cable at all. Second with cable of about 2.5m open on far end.

[ferferga]

Thank you very much holvoetn, really appreciate this!

So I was right, it looks like the distance was not displayed because of Winbox. I’m purchasing a handful of them then, thank you very much!

@jaclaz I guessed so, but yes, wanted to confirm regardless. Thank you very much for your input as well!

[jaclaz]

But did you use WInbox 4 (the new, hip thing) or the (good?) ol' Winbox 3?

[ferferga]

I’m still mostly using Winbox 3 and the Android app, with that I had no problems showing the distance on my RB5009.

However, it’s in @holvoetn first set of screenshots where Winbox 4 was used, and the field for the cable distance was missing, hence why I asked for a test with the CLI (which shows the result completely fine, hence confirming it’s not a feature missing in the mAP, but rather a visualization bug in Winbox).

I also had a problem a few weeks ago with inconsistencies (in the registration view of WiFi clients, clients connected through ft-wpa2-eap appeared as ft-wpa2-psk in Winbox, but not in CLI. This has been already reported to Mikrotik support and it’s on track to be fixed), hence why I was extra careful before extracting any conclusion from the Winbox screenshots in this thread.

Hope that clarifies things for you.

[jaclaz]

Actually It clarifies little.
Regarding distance in cable detect:
CLI works, OK.
Winbox 4 does not.
Does Winbox 3 work?

It did work on the hap lite when I made the mentioned tests (on 6.4x.something).

If all the above Is correct, then It Is not a "Winbox" problem but a "Winbox 4" one.

Or maybe depends on the Ros version?

[holvoetn]

It's a Winbox4 thing ...

[jaclaz]

Q.E.D.

I like adverbs :
"unexpectedly distance in cable-detect doesn't work properly in Winbox 4, while it works just fine both in CLI and in Winbox 3"

@jaclaz

Q.E.D.

Funny, used the same acronym past week with a colleague (about same age as me) who responded : What does that mean ?

[jaclaz]

Seemingly first used in 1598:
https://en.wikipedia.org/wiki/Q.E.D.#:~:text=The%20Latin%20phrase%20is%20attested,post-Renaissance%20mathematicians%20and%20philosophers.

so maybe too old, the new, hip thing is a solid black square, which is a bit difficult to express verbally, saying "Unicode U+220E" sounds silly.
