Serial Port Connections—
Controller PCB
Refer to the following diagrams for proper cable connections to the JAGXTREME
terminal’s serial ports COM1 and COM2. COM1 and COM2 are located on the Controller
board, which is positioned in the top slot.
The COM1 and COM2 terminal strips will accommodate wire sizes from 23 to 16 AWG.
The terminal strips may be removed to facilitate wiring. Removal of the terminal strips
permits easier viewing of the terminal designations printed on the board back plate.
COM1 20 mA (Controller PCB Serial Port)
The following diagram and table describe COM1 pin-to-pin cable connections using a
20 mA loop. The maximum recommended cable length for 20 mA interfacing is 1000
feet (304.8 meters).

* Pinout shown is for use with Plug In Adapter (8804 P/N 127358 00A; 8860 P/N 128019 00A).
** This cable also requires jumper pins 12 to 23 at the 8806 end of the Interface cable.
*** The 8856 requires the optional 20 mA to RS-232 Adapter (P/N 900936 00A) for 20 mA loop applications.
For enclosures using the pass-through
cable grips, you must pass the cable
through the grip, grommet, and
housing before wiring to the
connector.
