CHAPTER 5
INPUT/OUTPUT CONNECTORS
5.0 GENERAL
The TYMSERVE Input/Output connectors are located on the rear panel of the unit. These
connectors provide inputs for timing sources, general purpose timing outputs, the Ethernet AUI
connector, GPS connector (-GPS version only), an RS-232 serial port, and AC power entry.
5.1 ETHERNET AUI CONNECTOR
The Ethernet AUI connector provides the network connection. The connector is labeled
"ETHERNET AUI".
5.2 SERIAL PORT CONNECTOR
The RS-232 serial port connector is a 9 pin 'D' connector (male) with pinouts which are
equivalent to an IBM PC (Tx on Pin 3, Rx on Pin 2, Ground on Pin 5).
5.3 RJ11 CONNECTORS
The RJ11 connector labeled 'RJ2' is used on the -ACTS version as the phone line connection, and
RJ1 is not used. These connectors are not currently used on the -GPS or -IRIG versions.
5.4 AC POWER ENTRY MODULE
The AC power entry module accepts a standard 3-prong detachable power cord and also houses
the AC power fuse. The fuse is housed in a pull-out drawer which has room for a spare fuse. Be
sure to replace the fuse with the same rating as the one found there.
5.5 TIME CODE IN BNC (-GPS, -IRIG)
The time code input BNC accepts the input time code signal when time code is used as the
timing source.
