Figure 4-8: CPU Connector Pin-Outs for COM1 & COM2 in RS-232 Mode
Teledyne Instruments offers two mating cables, one of which should be
applicable for your use.
Part number WR000077, a DB-9 female to DB-9 female cable, 6 feet long.
Allows connection of COM1 with the serial port of most personal computers.
Also available as Option 60.
Part number WR000024, a DB-9 female to DB-25 male cable. Allows
connection to the most common styles of modems (e.g. Hayes-compatible)
and code activated switches.
Both cables are configured with straight-through wiring and should require no
additional adapters.
To assist in properly connecting the serial ports to either a computer or a modem,
there are activity indicators just above the RS-232 port. Once a cable is
connected between the analyzer and a computer or modem, both the red and
green LEDs should be on. If the lights for COM 1 are not lit, use small switch on
the rear panel (Figure 3-4) to switch it between DTE and DCE modes (see
Section 4.11.4). If both LEDs are still not illuminated, check the cable for proper
wiring.
