Machine Connections

ACC-2P Ethernet RJ45 Connector (J10 Port)

This connector is used for Ethernet communications from the ACC-2P to a PC, and it is provided when

ACC-2P Option 1B is ordered. The PC must have a card dedicated solely to the PMAC network. The

appropriate Category 5 10/100-Base T network cable that mates to this connector can be readily

purchased from any local computer store. The type of network cable to purchase depends on the

configuration to the host PC.

When making a direct connection to a Host communication Ethernet card in a PC a “cat 5 networking

crossover cable” must be used. A standard cat 5 straight through networking cable cannot be used in this

scenario. When using a connection to a network hub or switch, the standard cat 5 straight through

networking cable must be used, and not a crossover cable.

Performance can be degraded seriously by the use of a hub or switch. Network hubs or the more

intelligent network switches have processors inside them, which can add delays of at least 15msec to the

PMAC communications.

ACC-2P USB Connector (J1 Port)

This connector is to be used in conjunction with USB A-B cable, which can be purchased from any local

computer store, and it is provided when ACC-2P Option 1A is ordered. The A connector is connected to

a PC or Hub device; the B connector plugs into the ACC-2P J1 port.
