4.7 Setting Serial Remote and CIF Port
Parameters
The serial port parameters for both the Remote and CIF (Computer Interface) ports are set
through the front panel. The Remote port can be configured either for use with the CHPA
Remote panel or as a user-configurable port that supports the same protocols and command set
as the CIF port. The CIF port is typically used with a user's remote computer. These ports are
described in detail in Chapter 3, "Interfaces."
To change the factory default settings for the Remote port, perform the following steps:
1. Press the SPECIAL key followed by the (decimal) button.
2. Key in 18, the display will change to RMT CONFIGURATION.
3. Repeatedly press the FUNCTION button to review each selection under this menu.
•
If a CHPA Remote panel is to be used with the unit, the entry for PORT TYPE should be
RMTPNL. Use the arrow keys to select this entry. Now, no other entries will appear
under RMT CONFIGURATION and the CHPA is ready to use with the CHPA Remote
panel.
•
If the user configurable port option is desired, set PORT TYPE to USER.
4. Now, repeatedly press the FUNCTION button to cycle through the serial port and protocol
settings. Use the arrow keys to select the desired settings.
In addition to the parameters set in the above procedures, both ports have hardware settings
that may require adjustments. See Chapter 3, "Interfaces," for descriptions regarding
termination resistors (both ports) and RS-232 or

4.8 Verifying RF Output Level

After verifying the factory settings and test functions of the CHPA in Standby state, the next
step will be to place the CHPA in the Transmit state to verify the RF Output operation. (Refer to
Table 5-1 in Chapter 5.) Perform the following steps:
1. Verify that STANDBY LED and LOCAL are indicated on the display; repeat steps 1-3 under
"Power-On Self-Test and Heater Time Display" if they are not.
2. Verify that the RF Input and the RF Output are connected to a matched source and test load.
3. Set the display to indicate RF settings in watts. To do this
a. Press the SPECIAL button followed by the (decimal) button.
b. Key in 03, the RF Inhibit selection will appear on Line 4.
c. Press the FUNCTION button once—RF SETTING will appear on Line 4.
d. Press either arrow key until Line 4 reads WATTS.
