2.2.2 Step 2 — Connect Programming Cable
The programming cable connects the RCM3700 to the PC running Dynamic C to down-
load programs and to monitor the RCM3700 module during debugging.
Connect the 10-pin connector of the programming cable labeled
the RCM3700 as shown in Figure 3. Be sure to orient the marked (usually red) edge of the
cable towards pin 1 of the connector. (Do not use the
normal serial connection.)

NOTE: Never disconnect the programming cable by pulling on the ribbon cable.
Carefully pull on the connector to remove it from the header.
NOTE: Be sure to use the programming cable (part number 101-0542) supplied with this
Development Kit—the programming cable has blue shrink wrap around the RS-232 con-
verter section located in the middle of the cable. The simplified programming cable and
adapter board that are supplied with the Ethernet Connection Kit may also be used as
shown in the inset diagram above. Programming cables from other Rabbit kits are not
designed to work with RCM3700 modules.
Connect the other end of the programming cable to a COM port on your PC.
NOTE: Some PCs now come equipped only with a USB port. It may be possible to use
an RS-232/USB converter (Part No. 20-151-0178) with the programming cables men-
tioned above. Note that not all RS-232/USB converters work with Dynamic C.
