Description The Patton Model 2100 Series of transceiver/MAUs allows Ethernet 802.5
AUI ports communicate over twisted pair or thin coax cable. Drawing all
necessary operating power from the DB-15 AUI interface, the Model
2100 Series requires no AC power or batteries for operation. The Patton
Model 2100 supports twisted pair cable runs to 300 feet (91.2m) for connection to 10Base-T hardware such as hubs and repeaters. It incorporates autopolarity detect/reverse, jabber protection, and collision detection, as well as seven LED indicators. The Patton Model 2100LC is
identical to the Model 2100, except that there are no LEDs. The Patton
Model 2102 connects to a thin Coax LAN and has a switchable “heartbeat” function, as well as an adjustable collision detect level.

TRANSCEIVER/MAU
MODEL 2100/2100LC (10Base-T):
jack on 10Base-T twisted pair port LEDs: (Model 2100 only) Power On=red,
Link=green, Polarity=yellow, Collision=red, Receive=green, Transmit=green,
Jabber=red Link Parameters: Duration between transmit link pulses: 8mS(min) /
24mS(max); duration between receive link pulses: 3mS(min) / 105mS(max)
Collision Parameters: Collision signal ON/OFF delay (CI+/-): 900nS(max); collision to end of AUI loopback ON (DI+/-): 800nS(max); start of AUI loopback to end
of collision: 100nS(max); Jabbering node isolated from network if jabber surpasses a 26mS transmit time; the jabber function will inhibit transmission (except for
link pulses), discontinue AUI loopback, and send a collision signal on the AUI
CI+/- circuit
MODEL 2102 (10Base-2):
connection to network medium Maximum AUI Cable Length: 150 feet (45.6m)
Heartbeat Function: Can be disabled to allow operation with 802.3 repeaters
Collision Detect Level: Can be adjusted to detect collisions only when unit is
transmitting or even when unit is not transmitting MAU Functions Implemented:
Transmit, Receive, Collision Presence Detection and Jabber Lockup Isolation:
500 VAC, rms for one minute between the DTE physical layer circuits and the
coaxial trunk cable
GENERAL
necessary operating power from pin 13 of the DB-15 AUI interface Dimensions:
2.25"L x 1.69"H x 0.75"W (5.7 x 4.2 x 1.9 cm)
Compliance: IEEE/ANSI 802.3 compliant Power Supply: Draws
Connectors: DB-15 male on AUI port, BNC female
