Programming Over LAN

Communicating with the HP 16500C

Communicating with the HP 16500C

You can communicate with the HP 16500C in several ways. If you NFS mount your logic analysis system, it behaves like a disk drive on your LAN and programs control it by writing to the \system\program file. The other common way to control the instrument is through telnet or another socket-style connection.

The HP 16500C must be turned on and completely booted up before you can mount the system to your network. Once power is applied to the system and the System Configuration menu is displayed, allow an additional 15 seconds before attempting to connect to the system.

The LAN connection does not provide real-time programming control. Due to the message handling protocol of Ethernet LAN, messages take an indeterminate amount of time to reach their destinations. There can be no guarantee that commands sent from your computer will reach the HP 16500C in a timely way, although the majority of messages do.

LAN Addressing

All devices on an Ethernet LAN are uniquely identified by their Ethernet address. The Ethernet address is set in the hardware of any Ethernet- capable device.

However, the utilities you use to communicate with the HP 16500 Logic Analysis System follow the TCP/IP protocol. This protocol assigns unique IP addresses in software. When you connected your logic analysis system to your LAN, you or your system administrator assigned an IP address to the HP 16500C. Use this address to communicate with the HP 16500C. You can check the address by selecting LAN Settings in the System Configuration menu.
