38 Select SLC 500 I/O Modules
BASIC Development Software (1747-PBASE)
BASIC Development Software, an optional DOS-based software package, provides a
structured and efficient means to create and debug BASIC programs. It uses the personal
computer to facilitate editing, compiling, uploading, and downloading of BASIC
programs. The PC requires 640 Kbytes of RAM, a fixed disk drive with 2 Mbytes of free
disk space, and DOS version 3.1 or later.
Bulletin 1492 Wiring
Options
Wiring systems consist of interface modules (IFM) and pre-wired cables that replace the
terminal blocks and up to 50% of the point-to-point wiring between the SLC 500 and
field devices. Pre-wired cables connect directly to the IFM and have the Removable
Terminal Blocks (RTBs) of most 24V ac/dc and 120V ac 16- and 32- channel 1746
discrete I/O modules. The IFMs allow you to conveniently incorporate 1, 2, or 3 wiring
terminals per I/O point, field-side voltage indicating LEDs, and/or output fuse
protection. I/O module-ready cables, with a pre-wired 1746 RTB on one end and free
conductors on the other, are also available for use with standard terminal blocks.

To find the interface module and cable for specific I/O modules using the following
tables, follow these steps:
1. Locate I/O module required. The top row in each table indicates the
I/O module for the I/O platform.
2. Locate the Interface Module Cat. No. column in the appropriate table.
3. Determine whether the interface module can be used with the I/O
module, indicated by a letter code in the appropriate Cat. No. column.
4. Build the Pre-Wired Cable catalog number: 1492-CABL_ _ _Letter
Code.
• The Letter Code in the table cell represents the suffix of the
pre-wired cable catalog number.
For example: 1492-CABLE_ _ _A.
• Specify cable length. Standard Lengths are 0.5 m, 1.0 m, 2.5 m, and
5.0 m. Replace the _ _ _ with 005, 010, 025, or 050, respectively, to
indicate the length. For example: 1492-CABLE010A = a 1.0 m cable
with Letter Code A.
