Installation IPE2500A and IPE2500A-MLS Paging Encoder/Desktop Controller
03/12 40
Multi-line Select (IPE2500A-MLS)
N OTE : This operation requires IPE2500A-MLS Desk Set or XMLS001A Field Install Kit.
The IPE2500A MLS should have a default archive programmed into it. If it does not, or if the
XMLS001A was purchased, install and configure the Line Select Option as follows:
Programming Changes
The following are necessary programming changes to make after installation of the line select option.
Refer to the CARD Suite Programming Software Help file for additional information.
1. Use the CARD Suite software to select the number of lines being used (2 to 4).
2. Set the line configuration for 4-Wire and Tone Control.
3. Assign each line a programmable button. Assigning a programmable button allows you to take full
advantage of the line select features. This is especially true if an indication of vox-detect on a line is
desired.
Line Configuration - Two/Four-Wire Selection
Each line must be configured as either two-wire or four-wire prior to installation. This selection is made
with jumpers on the multi-line select module. Use the table below to determine the associated jumpers
and shunt positions for each line.
N OTE : Refer to PCB layout drawing in the rear of this manual for jumper locations.
Jumpers Two-Wire
(Default) Four-Wire
Line 1 JU800, JU801 In Out
Line 2 JU802, JU803 In Out
Line 3 JU804, JU805 In Out
Line 4 JU806, JU807 In Out
MLS Line Termination
Line termination can be installed for each line on the multi-line select module. The board contains a
560-ohm resistor for line termination. Line termination should be installed if only one desk set is
connected to the line or the desk set is a parallel desk set, and is farthest away from the tone remote
adapter. To install line termination for a particular line, install the appropriate jumper from the table
below.
N OTE : Refer to PCB layout drawing in the rear of this manual for jumper positions.
Line Termination Jumpers Default
Line 1 JU812 In
Line 2 JU813 In
Line 3 JU814 In
Line 4 JU815 In
