Programming entrance stations using the GT Setup Tool on Windows
Step 1: Open the GT Setup Tool and click the Create new site radio button. If already in the program, under File,
select Create new site(N).
Step 2: Leave the standard options as shown, then click Next .
Step 3: Enter a Site Name and indicate if GT-MCX or GT-BCXB will be used. From the drop down menu, select the
Number of Guards and the Number of Entrances, then click
OK
.
Step 4: Click the + Entrance to show all entrance stations, then select the door station to program. Click Resident.
Enter a Unit # (required) and Resident Name (not required, but must type in all Caps).
If using the GT-SW, enter the Call Button #.
Step 5: Click Save , and then Yes .
PROGRAMMING: ENTERING TENANT INFORMATION
The GT-DMB(-N, -LVN), GT-MKB-N, and modular digital entrance stations must be programmed with the resident’s
information before tenant stations can be addressed. The resident’s information can be entered using the keypad or by
using the GT Setup Tool software.

Use the dip switch method of programming shown below when installing the GT-1C7, GT-1M3, or GT-2C. When
installing the GT-1A or GT-1D, use the handshake method shown on pages 14-15. If using a mix of stations that allow
for dip switch settings (GT-1C7, GT-1M3, and GT-2C) and stations that do not (GT-1A, GT-1D), it is recommended to
program all stations using the handshake method.
Step 1: Create an ID correlation table for the tenant stations using a binary / SW2 Dip Switch - ID chart.
The chart below is for up to 48 stations in a non-expanded system. Refer to the full chart on pages 23 and
24 for the dip switch settings for an expanded system.
Step 2: Set the SW2 dip switches found on the back of the GT-1C7, GT-1M3, and GT-2C according to the
correlation table created in the previous step.
Step 3: Enter the ID from the correlation table in Step 1 into the Unit Link-ID Setting for each station.
Step 4: Click Save , and then Yes .

DIP SWITCH SETTINGS: GT-MCX
Each GT-MCX must be given a unique section ID and IP address by setting its SW2 dip switch. The default IP
address of the GT-MCX is 192.168.1.51 for ID1 (192.168.1.50 + ID number).
Step 1: Keep the power switch OFF. Set SW3 dip switch 1 to ON (turns off DHCP).
Step 2: Set the SW2 dip switches 2-6 to the desired section ID (see chart below). The default IP address of the
GT-MCX will be 192.168.1.51 for ID1 (192.168.1.50 + ID number).

GT-MCX
GT-MCX: Network Adaptor
The GT-MCX connects a GT system to a network, allowing multiple GT systems to be tied together. Each system now
becomes known as a section and requires its own GT-MCX. There are two types of sections, the tenant section and
the main section. A tenant section can contain tenant stations, entry stations, and guard stations. A main section can
contain entry stations and guard stations.
The following steps in this guide cover programming for a single system with the GT-MCX network adaptor. If
programming a multi-building system, please refer to the GT MULTI BUILDING SETTING MANUAL (sections 4-6) for
complete programming instructions.

Step 1: Create an ID correlation table for the tenant stations using the binary / SW2 Dip Switch - ID chart.
The chart below is for the rst 48 stations in a non-expanded or expanded system. Refer to the full chart on
pages 23 and 24 for the dip switch settings for an expanded system.
Step 2: Set the SW2 dip switches found on the back of the GT-1C7, GT-1M3, and GT-2C according to the correlation table
created in the previous step.
Step 3: Enter Unit Link-ID Setting for each station represented.
