connection to the hub itself. If present, verify that the hub link LED for the
pressure scanner and the host computer are both active. If the hub is
functioning correctly, verify that the communications pins in the module
interface cable are wired as described in Section 2.3.4.1 and Appendix D.
! CAL LED should remain OFF
! PRG LED should remain OFF
! Busy (BSY) LED should blink 8-16 times at a rate of approximately 1 Hz (slower for
9021/9022), delay ON for approximately 5 seconds and then start to continuously
blink at approximately 100 Hz (rate dependent on number of internal averages). This
faster toggle rate may simply appear as a dimly lit LED. Note that the Busy (BSY)
LED will not begin its 100 Hz toggle rate if the dynamic IP addressing
(RARP/BOOTP) protocol is enabled and the module has not received a proper IP
address response.
Any significant variation from this power-up LED sequence is an indication of a possible cabling
or PC-280 microprocessor board error. If the proper power-up LED sequence is not achieved after
following the above suggestions, contact the Repair Department at Pressure Systems for additional
assistance.
6.1.2 Checking Module TCP/IP Communications
If the LED indicators of the 9016, 9021, and 9022 are correct, the module is normally capable of
proper communications. In order for communications to be established with a functional 9016,
9021, or 9022 (assuming correct interface cables are used), two user-controlled parameters must be
met. First, the module must be configured to obtain a proper (and unique) module IP address.
Second, the user’s host computer must have its TCP/IP communications interface properly
configured.
6.1.2.1 Module IP Address Assignment
Before an Ethernet 9016, 9021, or 9022 can communicate with a host computer, it must have a valid
IP address assignment. As explained in Section 2.3.4.1, there are two methods for assigning an IP
address to an Ethernet device, static and dynamic. The Static IP addressing protocol is the default
method for IP address assignment in the 9016 and 9021/9022. This is primarily because it allows
the module to assign its own IP address based on a factory default value. The Dynamic IP addressing
