Adapters
The development kit includes several adapters that support the following functions:
• Performing Range Tests
• Testing Cables
• Connecting to other RS-232 DCE and DTE devices
• Connecting to terminal blocks or RJ-45 (for RS-485/422 devices)
NULL Modem Adapter (male-to-male)
Part Number: JD2D2-CDN-A (Black, DB-9 M-M) The male-to-male NULL modem adapter is

NULL Modem Adapter (female-to-female)
Part Number: JD3D3-CDN-A (Gray, DB-9 F-F) The female-to-female NULL modem adapter is
used to verify serial cabling is functioning properly. To test cables, insert the female-to-female
NULL modem adapter in place of a pair of module assemblies (RS-232 interface board + XTend
Module) and test the connection without the modules in the connection.

Serial Loopback Adapter
Part Number: JD2D3-CDL-A (Red, DB-9 M-F) The serial loopback adapter is used for range
testing. During a range test, the serial loopback adapter configures the module to function as a
repeater by looping serial data back into the radio for retransmission.
