3-2-2. How to Use LED Display PDSP2113
If a personal computer is not available, service commands can be written and read using the LED display
PDSP2113.
1. As the PDSP2113 (Part No. 8-749-922-58) lead pin may break, use a 28-pin IC socket (1-526-659-
21, etc.) as far as possible. Be careful not to burden the board when inserting the socket.
2. With the power OFF, insert the PDSP2113 into CNI 212 on the IF-787 board for UP-D2600S or IF-
788 board for UP-D2600.
3. Turn on the power. The display below then appears.
