• 370 mA with vacuum pumps operating
• 320 mA with pressure pump operating
• 540 mA with all systems operating (and no encoder attached)

Encoder Reader

The Encoder Reader is pinned to match the ACK A-30 digitizer, and will provide selectable 12 or 24 volts. Tester is protected with internal glass fuse.

Individual gray-code lines can be displayed for troubleshooting.

Compatible with outputs of the following altitude encoders:

ACK (gray code, 1200, 2400, 9600 baud)

Shadin (gray code, 9600 baud)

Trans-Cal (gray code, 1200, 2400, 9600 baud)

Ameri-King (gray code)

The Encoder Reader is compatible with the following RS-232 protocols:

Garmin 1200, 9600 baud

Northstar 2400 baud

Shadin 9600 baud

UPS AT, Apollo 1200 baud

Trimble 9600 baud

Note: due to the many encoder versions, and their individual pin-outs, no encoder extension cable is provided. The operator may configure an extension cable as needed.

The encoder reader tests the operation of the altitude digitizer. It does not test the transponder!
