1.0 INTRODUCTION

The serial RS-232 interface is used to connect the system to a controlling computer, a display terminal

(CRT), or a printing terminal. A modem can be connected directly to the system to provide telephone

line access.

NOTE: The software versions for these systems vary depending on when they were purchased and if

software upgrades have been installed. The version in which each function code first appeared is

indicated in a box next to its description in Section 7.

2.0 HARDWARE CONNECTIONS

The RS-232 interface for Port 1 is accessed via a 9-pin D-connector located on the bottom of the

console. The RS-232 interface for Port 2 is accessed via the 5-pin J-9 connector inside the console.

2.1 RS-232

Port 1 is a panel mount, 9-pin female type D-connector, wired in the DCE configuration. A modem

(DCE) may be connected to the interface using a null cable which reverses the wires for the

transmit/receive signals. A computer or serial printer (DTE) may be connected with a straight-through

cable. Port 1 does not require or activate any hardware handshaking signals unless this option has been

selected in the setup menu. RS-232 signals for Port 1 are wired to the 9-pin female D-connector as

follows:

Port 1 PIN

1 (DCD) Data Carrier Detect
