MAT-TUNER

FRONT PANEL

On the front panel there are six pushbuttons and four LED indicator lights.
[SAVE]: Save current configuration to memory.
[CUP] / [CDN]: Manually increase/decrease capacitance.
[LUP] / [LDN]: Manually increase/decrease inductance.
[TUNE]: Initiates a tuning cycle.
1.5, 2.0, and >3.0 LEDs: Indicate SWR.

REAR PANEL

The rear panel of the mAT-180H features five connectors.
ANTENNA: SO-239 connector for coax cable from antenna. When using the ANTENNA
connector, there should be no wire attached to the WIRE binding post.
RF IN: Connect a 50 ohm coax jumper cable from this standard SO-239 connector to the ANT
jack on the back of the transceiver.
Radio: This 4-pin mini-DIN connector is connected to the tuner control socket of the transceiver
through a matching control cable. DC power is also supplied over this jack.
WIRE: Binding post for connecting single wire antennas. When using the WIRE binding
post, there should be no coax cable connected to the Antenna connector.
GND: Connect to antenna system ground.

CONTROL CABLE

Control cables are used to transmit control commands between transceivers and tuners. Their
standard length is 50 centimeters. If it is desired that the mAT-180H is positioned farther from the
transceiver than this cable length allows, a custom cable will need to be constructed. This can be
accomplished in two ways: Cut the supplied cable and solder a jumper wire between all the
connections, or purchase new connectors and cable to construct a custom-length interface cable
from scratch.
