I am not familiar with the aloha- POS and I am doing the wiring for the POS system- I was told to run two cat5's per every POS - is it really nessesary to run two drops? what is the second run for?

I just want to understand the system wiring a little more.

Thank you
 
Yes. At least 2 wires to every terminal. Sometimes 3. Remote printers for the kitchen and other remote locations will need a drop as well back to the punch block. one drop is for the network, the other is for a serial uplink to run a remote printer. The dealer will patch over at the patch panel to drive the printer.

thanks!!!

In case i dont have space to run two more drops, can i split the one drop into 2 ? assuming they only use two pairs?
 
I wouldn't.
Two different communications (or 2 the same)in the same cable can cause cross talk and data corruption.

Here is a link to a diagram I give to contractors doing the cabling. It was done in Visio but I converted it to a bmp. You can download this and look at it.
The reason for running extra wires is because if term #1 drives the kitchen printer and it crashes, the user will move a patch cable over and change 1 flag in the software to have another terminal start printing the kitchen chits. And the support desk can do this over the phone.

Thanks ! I did not, I was able to run the drops !!!

But thank you very much !!!!!!

Now I will post another POS question, on a new post...
this time is POS MAx
 
DTSMAN,

Thanks a lot for the diagram.... I wired the job, tested all connections and are testing ok, but the ALOHA tech cannot print to 3 printers, the connection goes on but drops and gives an error message....I am using 568b your diagram says 568a- could this be the problem?

if not, what could be?

Thanks
 
Do you have a tester that tells you if all 8 cables are pinned straight through?


Both configurations A and B are straight through. 1-1, 2-2, etc. Make sure you didn't use a cross over cable to patch at the patch panel when you connected 14 to K1 for example. Remember all you are doing is creating a long null modem cable.

All the conversion to null modem cable should be done inside the RJ45 adapter on the printer port.

If you think it is the cabling move the remote printer next to the terminal, then test using a short 6ft null modem cable to prove programming is set up right or use a short certified patch cable to prove the adapters are keyed correctly. If needed, put the adapters on a short patch cable and ohm them with a multimeter to verify null modem configuration.

Most configurations will have a rj45 to db9 at the terminal end and an rj45 to db25 for the printer end. Newer Radiant hardware and some others will have their own adapter for the terminal side and you will have to match it to create the null modem configuration.
