2.1.1 CONNECTING THE WEIGH PLATFORM
The indicators mounted in an ABS enclosure ship with a 15 ft shielded load cell cable for
connection to weigh platform’s load cell(s) or junction box.
1. Plug the cable’s 14-pin Centronics-type connector into the load cell port on the rear
panel of the indicator.
2. Wire the bare wires and shield to the weigh platform’s load cell(s) or junction box using
the color codes shown in Figure 2-2.

2.1.2 CONNECTING THE SERIAL PRINTER, REMOTE DISPLAY OR COMPUTER
The TI-500 Series indicator comes standard with one full duplex RS-232 serial port,
designed for connection to either a PC or a serial printer. The same port may be also used
as a simplex, RS-232 port designed for connection to a remote display.
Figure 2-4 shows the serial port pinout. Refer to Appendix B for some suggested cable
diagrams. (A 9-pin Male D-type connector is required).
1. Plug the serial printer, remote display or computer communication cable (not included)
directly into the D-SUB9 serial port connector.
