| I need 2 Localtalk terminators for use with my asante talk box. I can’t seem to find Farallon corporations home page to get the terminators for the PhoneNet dongle box. Does anybody know of a good source to get the terminators I need? |

Go to your local RadioShack and pick up some 4 position RJ-11 phone plugs and 120 ohm resistors. Insert the legs of the resistor in the two outer positions of the RJ-11 and crimp. |

Tom, Does it matter which leg of the resister goes on which side of the RJ-ll plug? Also a few terminators that have have a ring around one of the legs what¹s that for? |
No, the resistor is symmetrical. The ring is just to have something to grasp when removing a terminator from a PhoneNet module. |

Thanks for the heads up on what they really are. I will try and make two I already have a crimper for RJ-11 plugs. |

Tom, does it matter what watt the resisters are. Should I only look for resisters that are exactly the same in color bands on them as the ones I already have in use? |
The resistors in my terminators are 120 ohm; that would be brown-red-brown. The fourth band, the tolerance, doesn't matter for this use. |

DJW-
It matters if their wires are too large to crimp in the RJ-11.

Checking a PhoneNet box here, the resistors look like 1/4 watt.

my have a brwon - red - brown - gold bands that I think mean 2 watt and +-5%? |
It's just an impedance match; two watt way too large. Try 1/4 watt or smaller. |

I have a bunch that use 1/8 watt resistors. If your run is under 100 feet, you really don't need to terminate LocalTalk lines at all. I still have some 3000 Ft LocalTalk runs around here, and they do need termination, but for things that are close, it really doesn't matter. Some LocalTalk Adapters are Self-Terminating as well. |

brown, red, brown, gold = 120 ohms (12x10), 5%. The wattage is never specified in the bands, only the physical size. Bruce may be right that they're 1/8 watt, though 1/4 watt resistors may be easier to find. As to whether they're really necessary, if you accidentally run the wire near an EMR source (big motor or high-current switch, for example), the resistors will help prevent packet corruption and consequent transfer rate degradation.

I am using them on a local talk network with a Blue & white G-3 so I need the Asante talk Box to get with the older network type that the printer and older Macs are on. Asante says I need to terminate at both ends I never tried it with out them. What might I find if I try them and they really needed them? Data transfer errors? Might it have intermittent problems? Or not even work at all? Does Asante know for sure that I need them or just want a user to use them so they don't get a ton or tech questions? |
Asante's just playing safe, since they cannot possibly know how far apart, and what quality cabling, you may be using. I've never had a problem with short cable runs, but I usually throw in the terminators anyway (since I have them.) If you need extra PhoneNet/LocalTalk connectors, I have a bunch lying around in the basement... |
