Front Panel
Communication Ports
The ACE IP Gateway module includes several communication ports:
On Board ports:
• USB Host 1/2 (HU1/HU2) - USB Type A host full speed ports for MDLC over IP
communication via the MotoTrbo digital mode radio system (up to two radios
attached to two USB host ports at one time).
No USB devices or USB Hubs other than
MotoTrbo radios are permitted.
• Serial 1 (SI1) – RS232/RS485 serial port (configurable)
• Serial 2 (SI2) – RS232 serial port
• Ethernet (Eth1) - 10/100BaseT Ethernet port
• DU1 – USB device port, Type B connector (for connection to the STS PC)
Plug-in port bays, where different types of ports can be installed:
• Plug-in 1 (PI1) – fits RS232, RS485, 10 MB Ethernet, 10/100 MB Ethernet, or Radio
Modem Plug-in option
• Plug-in 2 (PI2) – fits RS232, RS485, 10 MB Ethernet, or Radio Modem Plug-in port
option.
For the detailed specifications of each port, see ACE IP Gateway Module Specifications
below. For information on the cables and connectors, see Appendix C.
The ACE3600 Ethernet port performs an Auto-Negotiation procedure whenever a
peer device connection is detected at a 10/100 Mbps Ethernet port. The Auto-
Negotiation procedure guarantees that the speeds of ACE3600 and peer Ethernet ports
will match, whether or not the peer supports Auto-Negotiation. If the peer supports
Auto-Negotiation, the duplex of ACE3600 and the peer Ethernet ports also match.
It is recommended to configure the Ethernet port of the device connected to the
ACE3600 Ethernet port (e.g. switch, etc.) to Auto-Negotiation mode. This will
guarantee a full match of speed and duplex between the ACE3600 and the peer device
Ethernet ports. If the peer device Ethernet port does not support Auto-Negotiation,
set the duplex of the peer to half duplex to avoid the duplex mismatch problem.
