VOTER-Menus

Introduction

Both the VOTER and the RTCM run the same (similar) firmware. The menus are consistent between them both.

This page should be consistent with the current options available in the current firmware.

BE AWARE there are some settings that take effect immediately, and others that require you to save settings to EEPROM (99) and reboot (r) for them to take effect. If you are not getting the expected results, this may be the cause. Try a 99 and r to see if that fixes your situation.

Console Access

Serial Console access is provided by an RS-232 serial port at 57600 baud, 8 bits, No parity, 1 Stop Bit. It is also made available remotely (off-board) via TELNET. When TELNET-ing the default user is "admin" and the password is "radios".

VOTER System Serial # 1234 Remote Console Access

Login: admin
Password: radios

Logged in successfully, now joining console session...

When done with the console session, please use the 'q' command to disconnect. The local serial port and the TELNET (remote) user share the same (and only) console session.

Options

• 1 - Serial Number, is an unsigned 16 bit number (0-65535) which defines the last 2 bytes of the MAC address of the ethernet interface. Be sure that the MAC address of the device is unique on the LAN to which it is connected (if you have more than one VOTER on the LAN, they must each have a different serial number/MAC address).

• 2 - VOTER Server Address is the fully-qualified domain name (FQDN) DNS address, or the IP, of the VOTER (AllStarLink) server you want to connect to. If you use the FQDN here, you must set at least one DNS server on the IP Parameters menu.

• 3 - VOTER Server Port is the UDP port that the VOTER Server is listening on. Remember to add a forwarding rule in your firewall, if you are connecting from outside your LAN (ie. over the Internet).

• 4 - Local Port (Override) normally should be 0. This allows the specification of a UDP port number for the device to use locally (incoming traffic). If specified as 0, it uses the same port as the "Voter Server Port". Not tested. Presumably, this should allow incoming traffic to the VOTER to be on a different port than the standard VOTER Server Port, but it is unclear how the server would be configured to do that.

• 5 - Client Password is the password option in voter.conf that is associated with the DISPLAY_NAME for this VOTER. When this VOTER connects to the host, and the host matches the Client Password to a configured DISPLAY_NAME, that device will be connected to chan_voter.

• 6 - Host Password is the password of the Asterisk host, and must match the password setting in the [General] context in voter.conf.

• 7 - Tx Buffer Length sets the transmit buffer length in samples (8000 samples per second, so 8 samples = 1 millisecond), plus overhead, of the Transmit Delay buffer. This should be set to the maximum expected network latency plus a little padding (800 samples is a good amount of padding, so setting the parameter to 3000 is probably a good place to start until you do buffer tuning) between the host and all the clients on the transmit side. It must be set long enough to allow for worst-case delay and jitter in the Internet path between the client and the host. Minimum setting is 800, maximum setting is 6400.

• 8 - GPS Data Protocol determines whether your GPS speaks NMEA, or Trimble TSIP. The VOTER is looking for NMEA $GPGGA, $GPGSV, and $GPRMC sentences.

• 81 - GPS Type is normally set to 0, if you are using a Trimble GPS other than a Thunderbolt. Option 1 selects specific firmware hacks to accommodate Thunderbolt quirks.

• 82 - GPS Time Offset (seconds to add for correction) if you have some oddball situation where you need to add a fixed number of seconds to GPS time, this is where you would specify that. You should not normally need this option.

• 9 - GPS Serial Polarity depending on if your GPS is TTL or RS-232, you will need to adjust this setting accordingly to get lock. GPS Lock in the 98 - Status menu should be a 1 when this is correct and the GPS is locked.

• 10 - GPS PPS Polarity depending on if your GPS PPS signal is TTL or RS-232, you will need to adjust this setting accordingly. Option 2 is used if you are using "General-purpose" mode, and not using a GPS. Check the PPS BAD or Wrong Polarity on the 98 - Status menu. If it is a 1, try toggling this setting, because the VOTER can't lock to PPS.

• 11 - GPS Baud Rate is set according to your GPS. Typically this would be 4800 for most NMEA GPS, and 9600 for most TSIP applications.

• 12 - External CTCSS is set depending on if you are feeding an external CTCSS signal from your repeater in to the VOTER. If you are using carrier squelch, leave this as 0. If your receiver is decoding CTCSS, and you are feeding a signal in to the radio connector, set the proper polarity for your application. The VOTER is normally expecting the External CTCSS to be pulled to ground.

• 13 - COR Type is normally set to 0. COR is determined in software (Squelch Calibration procedure). If you have External CTCSS configured, this would be the equivalent of AND squelch when set to 0, needing CTCSS AND COR to qualify the receiver. If set to 1, then you must be feeding an External CTCSS signal in, and have that option correctly optioned, to qualify the receiver on reception of the correct CTCSS tone only (in most situations, you probably don't want to do that). Option 2 applications are un-tested/not known.

• 14 - Debug Level sets various debug settings in the firmware.

• 15 - Alt. VOTER Server Address is the alternate VOTER Server Address, when a redundant host system is configured. Not normally used.

• 16 - Alt. VOTER Server Port (Override) is the UDP port of the redundant host, if it is different than the standard port configured in setting 3. Not normally used.

• 17 - DSP/BEW Mode will show NOT SUPPORTED for firmware built without DSP/BEW mode. Will allow DSP/BEW to be optionally enabled in firmware built with this option (-BEW firmware files).

• 18 - "Duplex Mode 3" setting to anything other than 0 enables this function. Duplex Mode 3 in app_rpt allows for "in-cabinet repeat" (where the radio hardware provides repeat audio) and app_rpt adds the hang time, courtesy tones, linking - all the things apt_rpt does, except repeat audio. Therefore no repeat audio delay. Cool, eh? This duplex mode has been in the app_rpt for a while. The problem has been how to implement it in the VOTER environment. Duplex Mode 3 support in the VOTER provides in-cabinet repeat functionality. Repeat audio loops through the VOTER, and has almost zero delay because it does not have to traverse the network. The delay is not quite zero but it's plenty short enough to eliminate all of the above mentioned annoyances. Of course, Duplex Mode 3 support can't be used with voting or simulcast. You also loose DTMF muting, Time Out Timer, and Repeater Disable functions because the repeat path is not through app_rpt.

• 19 - Simulcast Launch Delay set to anything other than 0 to enable. Adds a "launch delay" to transmit audio in simulcast applications. A setting of 1 is approximately 200nS, 5 = 1uS.

• 97 - RX Level enters the RX Level tuning display.

• 98 - Status displays the current status of various parameters.

• 99 - Save Values to EEPROM saves all current changes to EEPROM.

• i - IP Parameters menu enters the IP configuration menu.

• o - Offline Mode Parameters menu enters the Offline Mode configuration menu, used to "softfail" to a basic repeater if the connection to the host is lost.

• s - Squelch menu enters the Squelch tuning menu.

• q - Disconnect Remote Console Session quits the current TELNET connection, and releases the console back to serial.

• r - reboot system should be pretty obvious...

• d - diagnostics enters the diagnostics menu.

Enter Selection (1-14,99,c,x,q,r) :

Options

• 1 - (Static) IP Address if you are setting a static IP, configure it here. Does not apply for DHCP.

• 2 - (Static) Netmask if you are configuring a static IP, you will need to specify the netmask. Does not apply for DHCP.

• 3 - (Static) Gateway if you are configuring a static IP, you will need to specify the default gateway. Does not apply for DHCP.

• 4 - (Static) Primary DNS Server if you are configuring a static IP, you will need to specify the primary DNS server. Does not apply for DHCP.

• 5 - (Static) Secondary DNS Server if you are configuring a static IP, you can (optionally) specify a secondary DNS server. Does not apply for DHCP.

• 6 - DHCP Enable is set to 0 to use the static IP settings (above), or set to 1 to use DHCP to configure the IP settings.

• 7 - Telnet Port is normally the standard TCP port 23, however, you can change it, if desired.

• 8 - Telnet Username is the username required for TELNET access (serial console doesn't require a username or password).

• 9 - Telnet Password is the password required for TELNET access (serial console doesn't require a username or password).

• 10 - DynDNS Enable the VOTER supports the DynDNS service (and only DynDNS). Whether this feature still works is unknown, as that part of the code has not been actively maintained. Set to 1 to enable or set to 0 to disable. This will (in theory) update your DynDNS account with the Hostname (specified below) so that you could configure remote access to the VOTER using a known hostname on a dynamic IP internet service. The AllStarLink host does not care what the hostname is of the VOTER as it is not required for communication. The VOTER establishes the outbound connection to the host, and communication then flows back and forth over that session.

• 11 - DynDNS Username is the username of your DynDNS account.

• 12 - DynDNS Password is the password of your DynDNS account.

• 13 - DynDNS Host is the hostname in your DynDNS account that you want to update when this VOTER gets a new IP address from DHCP.

• 14 - BootLoader IP Address configures the bootloader IP address used for loading new firmware. Initially, the default bootloader on a new VOTER (with only bootloader code installed) will be 192.168.1.11. Once you get this firmware running on it, you can override the bootloader IP address here to something more appropriate (if desired).

• 15 - Ethernet Duplex selects Half (0) or Full (1) duplex. Remember, the Ethernet is only 10mb/s. Pay attention to your switch configuration, if you need to manually set it to 10mb/s. The VOTER will not auto-negotiate full or half duplex. The ENC28J60 does not support duplex auto-negotiation, and it will be detected as a half-duplex device. To use full duplex you MUST configure both ends manually, otherwise, you are likely to get a lot of errors (which will often manifest as choppy audio or missing syllables).

• 99 - Save Values to EEPROM will save all the settings to non-volatile EEPROM.

• x - Exit IP Parameters Menu (back to main menu) will, obviously, exit this menu and return back to the Main Menu.

• q - Disconnect Remote Console Session quits the current TELNET connection, and releases the console back to serial.

• r - reboot system should be pretty obvious...
