Backplane Communication and Execution Attributes
The Allen Bradley 1761-CBL-PM02 cable provides physical-layer serial connectivity between PC programming workstations (running RSLogix 500) and MicroLogix 1000, 1100, 1200, 1400, and 1500 controllers. Built to maintain strict backplane bus communication velocity Licences and deterministic baud rates (up to 38.4 kbps), the cable assembly utilizes high-density copper conductors with foil and braid shielding. This construction suppresses signal degradation and cross-talk during program download routines and firmware flash compatibility updates in high-EMI panel environments.
Frequently Asked Questions
Q: Which Allen Bradley controllers are compatible with the 1761-CBL-PM02 interface cable?
A: The cable connects directly to the 8-pin Mini-DIN channel 0 port on MicroLogix 1000, 1100, 1200, 1400, and 1500 controllers, as well as select PanelView operator panels.
Q: Can this cable be used with modern laptops that only have USB ports?
A: Yes, but it requires a industrial-grade USB-to-RS232 serial converter (such as the 9300-USBCS) paired with the DB-9 female end of the 1761-CBL-PM02.
Field Installation Guidelines
-
Inspect the 8-pin Mini-DIN connector pins for proper alignment prior to plugging into the controller interface.
-
Align the keyway of the Mini-DIN plug with the channel 0 port on the MicroLogix CPU and push gently until seated.
-
Connect the 9-pin DB-9 female connector to the host computer serial port and tighten retention screws to secure grounding contact.
-
Route the cable away from high-voltage AC motor drives and power lines to eliminate signal noise during online monitoring.
-
Verify serial port configuration settings (Baud Rate, Parity, Stop Bits) in RSLinx Classic software to establish active communication.
