Gen 3 models PTL 2.4x, PTL 2.4LD and TTS 3.7 will operate with Gen 1 units using program versions 1-9,
1-10 or 2-10.
It is important to note a single GEN 3 unit can be operated in compatibility mode with
Gen1. You cannot use additional Gen 3 units.
Due to the software structure of the Gen 1 system, unit ID’s are not alike (or interchangeable) between
the Gen 3 and Gen 1. For example, Gen 1 uses the unit ID of SECONDARY PHASE 1B and Gen 3 uses the
equivalent unit ID of SECONDARY 1. This unit ID structure has a bearing on which Gen 1 unit ID’s are
assigned, based on the layout selected at the Gen 3 primary unit. Refer to the chart below to determine
which Gen 1 secondary unit ID’s are required, per the selected layout.
Note: The numbered boxes indicate the assigned phase (i.e. 1 = phase 1, 2 = phase 2)

GEN 3 SETUP
GEN 1 Secondary Unit ID's
Note: The Gen 3 primary CU alters its radio protocol when operating in Gen 1 compatibility mode. This
may require the user to force a re-write of the radio channel on the Gen 3 radio modem. This can be
accomplished by ensuring the correct radio channel is set on the Gen 3 CU, then completing a power off/
on cycle. This will establish communication between the Gen 3 CU and all associated Gen 1 CU’s.
