ALPHA Serial Clock Manual

Network configurations—Adding serial clocks to an Alpha network

Alpha serial clocks can be connected together with each other or in a mix of

Alpha signs. Also, like an Alpha sign, an Alpha serial clock must be

terminated when it is the last device on a network.

In a network, one clock (or a PC attached to the network) is used to

synchronize all the other clocks to the same time. In a network composed of

all Alpha serial clocks, one clock must be set to master mode and the other

clocks set to slave mode.

Table 1: Networking Alpha serial clocks

(Example 1 — Clocks on an Ethernet network)

In this example of clocks on an Ethernet network, all clocks must be set to slave mode.

Item Part # Description

A 1088-8621 3 foot serial cable, RJ-11 to RJ-11
