4.11
Testing Optional Equipment
At this time, any optional equipment should be tested to verify its operation. Check the
following equipment as described.
4.11.1
Remote Control Interface
The CHPA features an RS-422/485 serial remote interface. It may be configured to support the
Remote control panel; or it may be independently configured to use the same protocols and
command set that are available through the CIF port. CHPA status is available at all times
through this port. Refer to "Setting Serial Remote and CIF Port Parameters" earlier in this
chapter for more configuration details, if necessary.
The CHPA uses an RS-422 serial remote interface to support a CPI CHPA Remote Control
Panel. (Refer to Chapter 3 for a discussion of how to use this port as an alternative port for
computer communications.)
For the purposes of the following test, the Remote unit should be used within sight of the
CHPA to assure that the Remote unit's appearance is consistent with the CHPA's front panel
report.
1. Verify that the Remote is attached to J6, a female 9-pin D-shell connector.
2. If the CHPA Remote panel is used, verify that the Remote Configuration is set for RMTPNL.
3. Verify that the CHPA is powered on and in the Standby state as indicated by the STANDBY
LED being lit.
4. Press the LCL/RMT pushbutton on the front panel until REMOTE appears in the upper left
corner of the display. (This indicates that the Remote Control Panel can now control the
CHPA.)
5. Perform tests at the Remote Control Panel to confirm that it not only has complete control of
the CHPA but that it has complete monitoring capabilities of all of the metering available on
the front panel.
6. If no more options are to be tested, switch off the main power to the CHPA, remove the RF
Input and Output test loads, and make the normal RF Input and RF Output connections.
