PK-232 – MBX OPERATING MANUAL COMMAND SUMMARY
4/91 A-82 207
Unconnected packets are sent as Unnumbered I-frames (UI frames) with the destination and digi-
peat fields taken from "call1' through "call9' options. When a destination is not specified, uncon-
nected packets are sent to "CQ" .
Unconnected packets sent from other packet stations can be monitored by setting MONITOR to a
value greater than "1" and setting MFROM to ALL.
The UNPROTO path and address is also used for beacon packets.
USers "n" Default: 1
Mode: Packet Host: UR
Parameters: "n" - 0 to 10 specifies the number of active simultaneous connections that can be
established with your PK-232.
USERS affects the way that incoming connect requests are handled. It does not affect the number
of connections you initiate with your PK-232. For example:
USERS 0 allows incoming connections on any free logical channel
USERS 1 rejects incoming connections if there are connections on 1 or more logical
channels.
USERS 2 rejects incoming connections if there are connections on 2 or more logical
channels. And so on, through USERS 10.
USOs ON|OFF Default: OFF
Mode: Baudot RTTY Host: US
Parameters: ON - Letters (LTRS) case IS forced after receiving a space character.
OFF - Letters (LTRS) is NOT forced after receiving a space character.
Use the USOS Command (UnShift On Space) when you want your PK-232 to automatically change
from figures to letters after receiving a space character.
When using Baudot RTTY in poor HF receiving conditions, a received character can be incorrectly
interpreted as a FIGURES-SHIFT character, forcing the received data into the wrong case. Many
otherwise good characters received after this will be interpreted as figures (numbers and punctua-
tion), not as the letters sent by the distant station. USOS ON helps reduce these receiving errors.
Vhf ON|OFF Default: ON
Mode: Packet Host: VH
Parameters: ON - Packet tones are shifted 1000 Hz.
OFF - Packet tones are shifted 200 Hz.
Use the VHF Command for immediate software control of the PK-232's modem tones. Changing
components or switch settings is not required.
Set VHF ON for VHF operation (default), and set VHF OFF for HF Packet operation.
NOTE: Be sure to change HBAUD to 300 bauds when operating below 28 MHz.
