7 900-CP1x or equivalent cable provides the physical connection between the PC and controller.
‡ Typically, an RS-232 to RS-485 converter such as the Cat. No. 900-CONVZ25 (see page 9-215) will be required between the personal computer (with
900Builder software) and the Bulletin 900-TCx controller. In that case, a 900-CPx or equivalent cable provides the physical connection between the
converter and the PC. RS-485 allows linking up to 31 controllers with a single personal computer.
§ Series B provides baud rates up to 57.6 K bps.
