3. Installation
• 300 Bd AFSK (modem tones are fixed to 2300/2100 Hz, High-Tones)
• 1200 Bd AFSK
• 9600 Bd FSK (direct-FSK, compatible to G3RUH standard)
• 19200 Bd FSK (direct-FSK, compatible to G3RUH standard)
The module does all signal processing while the packet protocol is processed by the PTC-IIpro.
The installation and operation of the packet module is explained in detail in the main manual
which you can find on the CD-ROM and on our homepage.
3.7.1 Assembled cables
Many modern transceivers from KENWOOD, ICOM and YAESU are equipped with a so-
called Data-Connector, which usually is a 6 pin Mini-DIN on the rear side of the transceiver.
For this connector we can supply 2 ready assembled cables, one for 9K6 and the other for 1K2
Packet-Radio operation. Refer to the list of accessories in chapter 5 on page 52.
3.8 GPS
With the PTC-IIpro and the PTC-IIex two handshake lines (pin 4 and pin 9 of the RS232
connector) are used as secondary serial port, which is used to communicate with e.g. a GPS
receiver when connected. For a detailed description on how to connect a GPS receiver refer to
the chapter GPS in the manual. For easy connection a so-called Y-cable is available as
accessory (refer to chapter 5 on page 52).
The PTC-IIusb and PTC-IInet use a 3-pole screw terminator to connect to a GPS reciever. This
input is compatible with 5V-TTL and RS232/V24 signal levels. This pins are assignes as
follows:
