Female DB25 to male DB25. Line powered RS530 to RS232 converter with internal null modem function. Frequently used when moving connections from an AI patch panel to a T40 patch panel (PP-20).
CBM of America’s ADP-RS530-SYNC is a compact device adapting RS530 and RS232 serial links over DB-25 connectors. The most common application of this adapter is migrating a circuit from an AI patch panel to a DCE RS232 port as on a Cisco or a TRDC T40-series terminal server. As these installations are typically already equipped with a DB-25 null cable, the ADP-RS530-SYNC applies another null in its internal pinout to connect through a straight cable to the DCE device at the RS-232 end. Although it is an active device it derives power from the serial ports themselves and requires no fuse assignment. Female standoffs and male captive screws, both threaded for 4-40 UNC, allow for cables to be secured at both ports.
