CE-232 TECHNICAL INFORMATION GUIDE

The CE-232 is a point-to-point device that allows the extension of eight control signals far greater

in distance than that of conventional RS-232. The CE-232 is terminated to a DCE type device

(on the RS-232 port) at one end of the communication link. A cable, fully shielded, is then

terminated to the CE-232 and attached to another CE-232 at the corresponding end. The

CE-232 transmits an inverted RS-423 signal. This allows all control signals to be transmitted,

bi-directionally for distances that may equal up to 5000 ft.

VOLTAGE SELECTION

It is very important to check that the unit is set to the correct voltage setting for your application

before applying AC power. Located on the rear of the unit you will find a rotary 110/220 VAC

switch. Using a coin or small screwdriver, gently turn the switch to the appropriate power

position as required for your installation (110 or 220 VAC).

Located on the back or rear of the product you will find an IEC Power receptacle. This

receptacle contains a fuse drawer. Two (2) fuses are located in this compartment. For 110

VAC +/- 10% operation the unit is equipped with slow blow 5 x 20mm 160ma Fuses, E.C.D. Part

# 714000. For 220 VAC +/- 10% operation the unit is equipped with slow blow 5 x 20mm 80ma

Fuses, E.C.D. Part # 714001. Spare fuses may be purchased by calling East Coast Datacom

or by calling the fuse manufacturer: Little Fuse at 1+ (312) 824-3024 or Shurter, Inc. at 1+ (707)

The PWR indicator and TXD, RXD, RTS, CTS, DCD, TXD and RXC which represent the RS-232 control signals. The control signal indicators act as a break out box in that installation and trouble shooting are a straight forward process.
