11.2 Adjusting Input and Output Levels
When a transceiver, other than those that have been verified to operate correctly, is connected,
there are times when adjustment of input/output levels may become necessary for RC-D710 and
the transceiver to function properly. Even when you cannot adjust the input and output levels on
the transceiver side that is connected, it is possible to adjust input and output levels on
the RC-D710 side using 3dB steps by using MCP-2A.
11.2.1 How to Configure Input/Output Levels of RC-D710
1. Turn the power of RC-D710 OFF.
2. Connect the PG-5G programming cable (serial communication cable) between the COM
terminal on the rear side of RC-D710 and a personal computer.
3. Start MCP-2A.
Click the “ ” button on MCP-2A and read the data from RC-D710.
4. Select “Data Terminal” from the Edit pulldown menu.
The configuration window for input/ output levels will open.
Figure 11-3 Data Terminal Window
PKD PIN (1200bps): 1200 bps output level
PR9 PIN (1200bps): 1200 bps input level
PKD PIN (9600bps): 9600 bps output level
PR9 PIN (9600bps): 9600 bps input level
* Input / output terminals for 1200 bps and 9600 bps are the same. However, levels have to be set individually.
Refer to the Help file for MCP-2A for details.
5. Click the “ ” button on MCP-2A and write the data to RC-D710.
6. Turn the power of RC-D710 OFF and disconnect the programming cable from PG-5G.
Note: In some transceivers, other than those that have been verified to operate correctly, the TNC data input/output line
which is connected to PKD/PR9 has not disconnected the DC voltage inside the transceiver. Therefore, there are
situations where the transceiver will not function properly even if input/output levels are adjusted correctly. Use
caution.
