Magnum Mini-Transceivers are equipped with an AUI port and either a
10BASE-T (RJ-45) connector or a BNC (10BASE2) connector. The AUI port
can be used to connect directly to the workstation or device in most cases. If
this is not possible, an AUI drop cable (which does not exceed 3 feet in length)
can be used.
LED/SWITCH SETTING DESCRIPTION & OPERATION
Each Magnum Mini-Transceiver is equipped with switches and LEDs to allow
for configuration and quick visual assessment of its operating condition.

OPERATION
The function of a Magnum Mini-Transceiver converts the station signal to
appropriate network media; i.e. it converts traffic signaling between station
signaling a nd 10BASE-T signaling.
The TP1 Twisted Pair Mini-Transceiver is designed to connect an existing AUI
device to a 10BASE-T (TP) network. (Note: By using a shielded AUI extension
cable, and selecting RED SQUELCH function switch to ON position, the unit
can be used on shielded twisted pair (STP) networks.)
The CT1 10BASE2 ThinNet Mini-Transceiver is intended to be used with
ThinNet coaxial, 50 Ohm, RG-58 A/U cable. Cable runs should not exceed 180
meters in total length. A 50 Ohm terminator is required at both ends of the
segment. Taps should be at least 0.5 meters apart.
