Can you use both the modem and printer ports for appletalk?

I just go my 8100/100 going today, so I put a fresh istall of OS 7.5.3 on there, and I did the same thing to my Powerbook 1400cs, thought with the restore CD. So, the both boot up and run great (the 8100 exceptionally well, because it has 122mb RAM) so i decided to pull out my old appletalking stuff, as set up a network.

That also was easy, and here is how its set up:

iMac G5 --ethernet--> PM 7500/450 --appletalk connectors--> PM 8100

but i would like to have the 8100 connected to the 1400cs, but the appletalk control pannel only lets me use the modem port or the printer port. i need to use both, so that i can have the line running from the PM 7500 to the 8100, then from the 8100 to the 1400cs. is there any way that i can use both the ports on the 8100 for appletalk?

Thanks,

John

Printer Ports

I'm pretty sure only the printer port works for AppleTalk. You need to string the boxes together. Plug one box into the 7500's printer port. That will lead to another box, which will plug into the 8100's printer port. From the box in the 8100 chain another cable going to the 1400. Each AppleTalk box has two ports allowing for incoming connectors. It's tough to explain in words, but I think you know what I mean. If not let me know and I can e-mail you a diagram or something.

IIRC no, you can only use one

IIRC no, you can only use one. However, if you need to daisy-chain multiple machines or printers through AppleTalk, you can pick up serial-port to RJ45 transcievers; each transciever has a pair of RJ45 jacks and you use normal telephone cables to daisy-chain between them.

EDIT: Here's what I'm talking about:

You can pick them up for much cheaper on eBay or the LEM Swap List.

No, you can use both ports, because currently the 8100 and 7500 are transfreing a 20mb file, both are connected throught the modem port. As for linking them toghether, I only have 2 of those little boxes, the ones that have 2 phone line connectors, and one is taken up but the termanator. The way I was going to connect the 8100 and the 1400cs was via a serial cable. Which I just verified works when I change the option in the appletalk control panel.

Dr. Webster, thats what I tho

Dr. Webster, thats what I thought. I guess I'll just have to buy some more.

Thanks anyways,

John

There are also dula port boxe

There are also dual port boxes for offical Apple style cables. They have a Serial plug to go to the Mac, and then two 3-pin MiniDIN ports to plug in the AppleTalk cables. I haven't seen/got terminators for them, so I dunno if they are needed.

Yes, but...

you can't use both at the same time. AFAIK AppleTalk doesn't support multihoming (using more than one port at once.)

RJ-11. (RJ-12?)

RJ-45 connectors (the ones usually used for ethernet) have 8 pins and are wider. RJ-11 connectors (commonly used for phones) are more narrow and have space for 6 pins, although the RJ-11 spec only requires pins 3 and 4 to be connected. JR-12 adds connections for pins 2 and 5, which are present in most cables even though they're not needed for the single-line phones for which they're most commonly used. IIRC, these transceivers only use the two RJ-11 pins.

I think those extra pins in R

I think those extra pins in RJ-11/12 are for people who upgrade to DSL internet.

John

BTW: Do you guys know of any file server programs that run on OS 7.5.5? Like appletalk, but that use other programs?

The extra pins in RJ-11 exist

The extra pins in RJ-11 existed long before DSL. Wink DSL operates on the same pair as a regular phone, but it works at a specific frequency that gets removed when you put the special filters on just before teh connection to a telephone.

The extra pairs in RJ-11 are there for extra phone lines. You can have up to 3 phone lines on a single RJ-11 plug, though most are only setup for 2.

Yeah, I got my RJ's confused. RJ45 is 8-pin, RJ-11 is 4 pin. You only need 2 pins for LocalTalk, though (I've heard of people back in the day using the spare pair of wires in their house's phone wiring to run LocalTalk).

Hate it when that happens Wink

I hadn't heard of using the RJ-14 (not RJ-12, that has all 6 pins connected. Hey, I did it too!) pins for localtalk, but it makes sense. I've seen projects that run power over the unused pins in RJ-45 connectors, though.

Well, the appletalk connector

Well, the appletalk connectors should be here by the end of the week; so by then the MT will be here and the network will be complete!

But I do have another question about two NuBus cards I found: They have and ethernet port, coax connector (token ring?) and an apple video connector. They have SSI printed on them, as well as "NuBus Ver 3".

When they are in the 8100, and I plug in an ethernet cable, I get a green light, so I'm assuming that they are decteing the signal ok. But I cant find out how to get then to work is OS 7.6!

Any ideas?

John

I presume that you are referring to an RJ45 ethernet connector. Ethernet also uses different types of physical connector and transmission media (cable).

john8520 wrote:

Thinwire ethernet. An IEEE standard.

john8520 wrote:

and an apple video connector

Probably an AUI ethernet connector for use with an external transceiver. Another IEEE standard. There were a couple of combo ethernet/video cards for the Mac but I doubt that this is one of them. Does the 15 pin connector that you associate with video use a screw fixing or a bayonet fixing? If there are no screws, it is probably AUI.

I have read about SSI ethernet cards but have never used one. I recall a discussion of these cards on the LEM mail lists twelve months ago.

Yep, I'd be absolutely positi

Yep, I'd be absolutely positive that a card that had both an RJ-45, and a coax, that also has a 15-pin port, would make that an AUI port. I've never seen a combo card that had both RJ-45 and coax, but also a video port.
