OMMUNICATIONS
A.1 AuxCom Overview
AuxCom, short for Auxiliary Communications, is a feature included on certain Ludlum in-
struments. An AuxCom port allows the instrument to expand its capabilities with a variety
of external devices through a standard serial interface.
A.2 Requirements
In order to take advantage of the AuxCom functionality, you will need the following:
• A serial or RS-232 serial option
• A wiring harness to connect the target device
• The correct mode set for the AuxCom port
A.3 Usage
Usage of the AuxCom port is generally very simple from the user’s perspective. Most modes
initialize everything to be plug-n-play; however, there are a couple of caveats.
If using the SLURM protocol, the user will need to pair the instrument with a mobile device
using the hot key listed below.
A.3.1 AuxCom Usage - Hot Key
There are two types of hot-key presses:
PIN Generation: If the UNITS and MODE buttons are both held for longer than 2 seconds
(2 beeps), the instrument will present the user with a PIN needed for pairing. Repeat the
process to clear the screen.
