C.22 Option 34: NTP/PTP Server 203
Option 34 using the Console, you will need an SSH client. These instructions use an SSH client
called PuTTY when describing the Console Interface. Option 34 comes by default configured for
an HTTP connection, and may be configured to use HTTPS.
C.22.2 Option 34 Setup
This section covers initial setup of the Option 34. Before the Option 34 can serve time accurately,
the clock must be locked to the GPS and stable. Once meeting these conditions, the Option 34 can
provide reliable time to a network. The three subsections below will guide you through this initial
phase of starting up the clock and configuring the Option 34.
The Option 34 can be ordered with either static IP addresses, DHCP assigned IP addresses, or
both static and DHCP. This information should help you decide how to configure the Option 34.
By default, the Option 34 is configured with port 1 assigned a static IP and port 2 assigned by
DHCP.
Note: If your Option 34 has fiber optic connectors installed, do not disconnect cable while clock
is operating or the NTP/PTP service may not recover. If fiber optic cables are disconnected while
clock is operating and service stops, power cycle the clock.
Default Port Addresses
By default, the Option 34 comes configured as follows:
Port 1 IP address -- STATIC: 192.168.0.232
Netmask 255.255.255.0
Gateway xxx.xxx.xxx.xxx
Port 2 IP address -- DHCP: xxx.xxx.xxx.xxx
Selecting the Option 34 in Clock
Before you can use the Option 34 in your clock, make sure that it is selected as an option. To check
the configured option:
1. Press the SETUP key until you reach “SET OPTION CONTROL” and press “ENTER”.
2. The 1088A/B has to option slots: the first is SLOT A. Press ENTER again.
3. Under SLOT B OPTION the second line will give the option name.
4. Use the UP or DOWN key to select “34” and press “ENTER.”
5. “Option 34” should now be selected in the clock.
Option Setup Using RS-232 Commands
To select Option 34, use a terminal program (HyperTerminal or Tera Term
3
) and null-modem cable.
Important pins for a null-modem cable are indicated in Table C.15 below.
1. Open a terminal program at the same baud rate as the clock. For the Model 1088A/B, the
default port settings should be 115,200 baud, 8 data bits, no parity and 1 stop bit.
2. Type the letter “v” to verify communication. It should return the firmware date code.
