blink per tracked GLONASS satellite.
The REC LED displays the data recording status.
• Green blinks – each blink indicates that data is being
written to the SDHC card.

• Orange blinks – the receiver is checking its internal file
system. During this operation, the file system is not
accessible for CDU (control display unit) applications
or for data recording. This operation may require from
fractions of a second to several minutes, depending on
the circumstances and the amount of internal memory.
• Solid Red – a fault condition with the receiver (no more
memory, no SDHC card inserted, a hardware problem,
or an improper OAF).

Radio Antenna and Pole Connectors
The SS antenna connects to the external antenna connector
on the GR-5 radome. The radio antenna uses a reverse
polarity TNC connection or BNC connection depending on
the installed radio modem.
The bottom connector connects the receiver to either a
standard 5/8'' thread pole/adapter or the quick disconnect.
SDHC and SIM Card Slots
The SDHC and SIM card slots reside under the batteries near
the base of the dome.
The SDHC card slot is located to the left of the MINTER
inside the battery pocket and connects an optional SDHC
card to the receiver board to provide memory. The data that
resides on the SDHC card can be accessed via the USB or

serial port, or Bluetooth. The following industrial-grade
cards were tested in the temperature range -30°C to 60°C (-
22°F to 140°F).
• Transcend® Ultra Industrial 2 GB
• APRO® Industrial 4GB
• SanDisk® Ultra II
• Swissbit® Industrial 2GB
Before using any other SDHC cards, consult with TPS
technical support about compatibility.
The SIM card slot is located to the right of the MINTER
inside the battery pocket and allows a standard SIM card to
be installed in the receiver. Once installed, the SIM card
provides a unique identification for the receiver’s GSM
module and enables the receiver’s GSM functionality based
on the subscribed services. The GSM module with the SIM
card installed can be configured via TRU. A SIM card can be
purchased from a local cellular provider.
