the unit should be power cycled at a convenient time to resolve this extremely rare condition. It the alarm is
still active after a power cycle, return the unit for repair.
6.16 Communication Problems
This section describes some of the errors associated with communications problems and some potential
sources of those issues.
6.16.1 LAN
LAN Connector unplugged.
DHCP
o
When the system is operating press the “Display” button on the front panel. If the IP
Address is set it should switch to those displays and give the local operator the IP
Address. If not, the IP Address was not set it will not display the IP Address and the unit
will assign an IP Address of 0.0.0.0. Plug the LAN Connector into the rear of the unit
and if a DHCP server is available, the unit should obtain an IP Address.
o
Power cycle the unit.
Static
o
Verify the static IP address Netmask, Broadcast IP, and Gateway were set properly using
the
network
command.
o
If incorrect, Use the
network_config
command to set the correct Mode, IP address,
netmask, broadcast, and gateway.
6.16.2 USB-to-Serial Adapter (94000-115200) (Command Port)
USB to Serial adapter the improper type (94000-115200)
Improper baud rate set on terminal serial port
o
115200,N,8,1, no flow control.
Incorrect serial cable type (requires Null Modem cable.)
6.16.3 External Reference Adapter (94001-5071A)
USB to Serial adapter the improper type (94001-5071A)
Incorrect serial cable type (requires Null Modem cable.)
Communication settings on the reference device are incorrect.
o
Refer to the 5071A manual and set the system to 9600,N,8,1.
Note:
Communications are only used when the external frequency reference is a hp5071A. If you are
using a different cesium clock use the
reference_type cesium
command to set the proper reference clock
type. This also applies when using the 5071A and the 4380A will not be communicating with the clock.
6.17 Syslog Command
All system error messages can be listed using the
syslog
command on the command port. The following
information is typically contained in this log during startup. The date/time will be set to Jan 1 00:00:00
when the system is first powered on or rebooted since the time is not set until the GPS receiver is tracking.
