Installation Procedure
Read the instructions completely prior to installing this converter
to the network.
Attach the UTP cable from the network to the RJ45 port on the
Model 5577. Attach a MAU or drop cable to the 15 pin AUI port
on the Model 5577. Slide the locking mechanism to secure the
device.
Apply power from the wall adapter unit, the POWER LED should
be lit.

Important: SQE (heartbeat) on external MAU’s attached to the
AUI port must be DISABLED for proper operation.
The 10Base-T standard employs the transmit-equalization method
with the added function of LINK test. A 10Base-T transceiver
can operate in a Starlan-10 environment by disabling the link test.
10Base-T Cable Requirements
The Model 5577 unit is wired in the same fashion as a 10Base-T
transceiver:
1
2
3
4
Pin 1 = TX+
Pin 2 = TX-
5
6
7
8
Pin 3 = RX+
Pin 6 = RX-
To connect to a HUB, simply wire 1, 2, 3, 6 straight through.
To connect another Model 5577 wire 1 to 3, 2 to 6, 3 to 1, 6 to 2.
Note: SQE on external MAU’s must be DISABLED for proper
operation.

AUI TO 10Base-T
• RCV/TP is lit when the unit is receiving packets from the
10Base-T network.
• COL/TP is lit when a collision is occurring on the 10Base-T
network.
• LINK is lit if connected to an active 10Base-T hub or another
Model 5577.
• POL is lit when the receive pair of the 10Base-T connection is
reversed, however, the converter will still work under this
condition.
• POWER is lit if the unit is receiving power from the adapter.
• RCV/AUI is lit when the unit is receiving packets from the AUI
network.
• COL/AUI is lit when a collision is occurring on the AUI
network.
