This allows the user to program information concerning the baud rate, data bits, parity, stop bits and serial repetition to ensure that the format chosen meets their requirements. Some of the other serial data messages have factory preset transmission formats to ensure that system interconnection is trouble free.

Operation The 4850 / 4860 Master Clock is fitted as standard with one RS232 & RS485/RS422 serial data output. The signals are accessed via the female DB9 connector labelled RS232/RS485 S1 mounted on the rear of the unit. Additional serial outputs (4860. S2 & . S4 versions only) The 4860 is optionally available with two or four RS232/RS485 serial data outputs. Where installed, these signals are accessed via the S2, S3 and S4 female DB9 connectors. If your 4860 is fitted with multiple serial ports, extra serial setting modes (S2, S3 & S4) will appear in the main programming menu to allow these ports to be individually configured using the procedure detailed below. (Please note: The RS232 level 1 pulse per second output is not present on pin1 of serial ports S3 & S4). Setting the Message Format The 4850 / 4860 has 71 different preprogrammed serial output messages. The desired message can be selected from the lists on page 7-2 and programmed into the 4850 / 4860 using the procedure on page 7-5. Please also refer to Appendix C for details of products compatible with the 4850 / 4860. Setting the Output Message Time Offset The 4850 / 4860 serial output message may be referenced to the current location setting (see section 4) or UTC/GMT as detailed in the procedure on page 7-5 . Status byte - ASCII value 30h-3fh undefined. 0 = Winter time, 1 = Summer Time 0 = not synchronised, 1 = synchronised 0 = no early warning bit, 1 = early warning bit Application Notes The 4850 / 4860 Information CD contains application notes detailing the use of the 4850 / 4860 with many different types of equipment. If you are unable to access the CD or require further information on the setup and use of the serial output please contact our technical support representatives. The Serial Messages table on page 7. 2 contains references to application notes which contain additional information specific to that serial message. User programmable serial settings Display bAud Setting Baud Rate Range 19 - 19200 baud, 96 - 9600 baud, 48 - 4800 baud, 24 - 2400 baud, 12 - 1200 baud. odd - Odd parity, EvE - Even parity, no - No parity. 1SE - 1 serial message every sec, 1nn - 1 serial message every min, 5nn - 1 serial message every 5 min, 1 Hr - 1 serial message every hour, 24 Hr - 1 serial message every 24 hrs at Midnight, 4An - 1 serial message every 24 hrs at 4 AM, rSE - On demand, next second edge.

[. . . ] Subnet Mask The subnet mask when combined with the IP address identifes the subnet (part of the bigger network) that the 4860net is connected to. Gateway Address The gateway address is used by the 4860net when it needs to send information to computers and devices which are connected to other networks and subnets. NTP Server IP Address This is the Internet Protocol address of the NTP time server that the 4860netclient uses as a Time Source. 8) Sb Gt nt D-1 Issue 2. 0 4850 / 4860 Master Clock Operating and Installation Instructions Synchronisation Status Display When in normal time display mode the plus and minus buttons can be used to cycle through the date, synchronisation and temperature status displays, as detailed on page 2-5. However, when NTP is selected as the synchronisation source, the synchronisation status display operates as detailed below NTP Synchronisation status - please refer to the table below for further information.
