user only needs a standard pin-to-pin serial (RS-232) or/and parallel (LPT) cable.
The serial connector (DB-9 Male) on the back panel of the unit is multi-functional and provides an interface for the CW-key and PTT signals from a logging program as well as the PC connection
for a CI-V interface that can be used to control an Icom radio from the logging program.
The Parallel port (DB-25 Female) on the back panel of the unit provides access to the first four Voice and CW messages from the PC logging program. Additionally, signals for the CW-key, PTT and Radio 1/Radio 2 switch are also fed into this port from the PC.
TRLog can be configured so that any LPT port can have all the functions available on the specific port. With older versions of CT, Radio 1/2 switching is only available on LPT2.
The Super Combo Keyer can be user-configured to accept either CT or TRLog signals on the LPT.
