  • Page 13 Ethernet. This can be done through the RS-232 ports or the USB port. The 20-62 must be set up as a TCP/IP server. You need to note the IP address and the port number when you previously configured the TCP/IP tab via the serial port. You will need to ensure that the IP address is valid.

  • Page 14: Configuring The 20-62 Using Sacoto

    Configuring the 20-62 using Sacoto Reading the configuration The initial configuration must be read from the 20-62 or from a file saved on disk. This may then be modified as required and written back to the 20-62. Sacoto configuration screen after reading data from the 20-62 or from a file.
  • Page 15 If the configuration has been read from a file, or from another 20-62, any differences from the configuration in Sacoto and in the configuration of the 20-62 is unknown. If you want to preserve the settings in the device and only make a few changes you should read from the 20-62 first. Write All If you want to duplicate a known configuration read from another 20-62, or restore a previous configuration saved on disk, then you should select “Device->Write All”...
  • Page 16 Frequency: Entered in MHz. This is checked against the selected channel spacing. Off-channel frequencies are not possible. Channel Spacing: The 20-62 can only transmit on channels which are multiples of 5 kHz, 6.25 kHz, 10 kHz or 12.5 kHz. This setting is only used for frequency selection and does not affect transmitter deviation or bandwidth.
  • Page 17 P a g e | 16 Trigger Input Configuration The 20-62 can be configured to transmit messages in response to the state of the trigger inputs. Features:  A message can be triggered by a high-to-low or a low-to-high transition.
  • Page 18 CAP code. SALCOM relay receivers are able to provide quick response when configured to use POCSAG rapid, giving faster response and more precise “on-time” control. POCSAG rapid should be used with short numeric messages like the Salcom relay protocol.
  • Page 19 P a g e | 18 Sacoto Message Format The Sacoto message format is based on the Salcom protocol, which includes baud rate, Numerial/Alphernumeric message type, CAPcode, function code and the message text.  The 20-62 can transmit at 512 or 1200 baud.

  • Page 21 “Remote server address” field. The “Current” or “Static IP address” is still required for the IP address of the 20-62 but the remote TCP/IP server does not need to know this. In TCP/IP client mode the 20-62 will only connect with the “remote server address”.
  • Page 22 The DHCP server will reserve the address for a “lease” period programmed into the DHCP server. This may be a day or a week, or as short as an hour or less. The 20-62 will continue to renew this lease as long as it is active, but if it is disconnected or powered off, the address may be reassigned to another device after the lease period expires.
  • Page 23 You can use this address as long as it remains valid on the network. Finding your PC’s IP address If you are using the 20-62 in client mode, you will need to know the IP address of your PC so the 20-62 can connect to it.
