Paccomm PC 320 PC Card

DESCRIPTION
The PacComm 320 series consists of two dual-modem HF AND VHF packet controller models. The units share many features, including excellent HF packet performance. The PC-320 is configured as a 3/4 size plug in card for PCs and compatibles. The TNC-320 is a conventional stand-alone TNC.

FEATURES COMMON TO BOTH 320 SERIES MODELS
Separate modem circuits for optimum VHF and HF operation. Uses the EXAR 2206/2211 PLL modem and 6 pole active filter for superb HF operation. Excellent HF carrier detection performance. The HF modem filter may be bypassed and the modem retuned to support VHF tones. Expanded auxiliary modem header supports PacComm's G3RUH 9600/19200 baud modem and PSK-1 satellite modem. Radio port selection is by a single keyboard command which also selects a separate heard log, radiolink and many other parameters. The AX.25 firmware uses the TAPR command set with numerous additional commands to support PacComm features and enhancements. Supports TCP/IP via the built-in KISS module. Personal Message System PMS with manual and reverse forwarding. The PMS allows the packet controller to support all standard packet functions while allowing messages to be entered or read by an over the air user.
