RS-232 cable; the converter is a DCE device. RS-422/485 cables. Recommended characteristics: 24 AWG twisted pair with a shunt capacitance of 16 pf per foot and 100 Ohm characteristic impedance. STEP 2 - Certifications & UL C1/D2 FCC Class A CE IEC 61850-3 IEEE 1613 UL CLASS 1 / DIVISION 2 WARNING INFORMATION SUITABLE FOR USE IN CLASS I, DIVISION 2, GROUPS A, B, C AND D HAZARDOUS LOCATIONS, OR NONHAZARDOUS LOCATIONS ONLY. CONVENANT À L EMPLOI DANS LES SITES DANGEREUX DE CLASSE I, DIVISION 2, GROUPES A, B, C ET D, OU DANS LES SITES NON HASARDEUX SEULEMENT. Field wiring connections must be made using 105 C minimum copper supply wires. Les connexions de câblage sur site doivent être réalisées en utilisant des câbles d alimentation en cuivre de 105 C minimum. WARNING - EXPLOSION HAZARD - SUBSTITUTION OF ANY COMPONENT MAY IMPAIR SUITABILITY FOR CLASS I, DIVISION 2. ATTENTION - DANGER D EXPLOSION - LA SUBSTITUTION DE COMPOSANTS PEUT ENTRAÎNER UNE ADÉQUATION À LA CLASSE I, DIVISION 2. WARNING - EXPLOSION HAZARD - DO NOT DISCONNECT EQUIPMENT WHILE THE CIRCUIT IS LIVE OR UNLESS THE AREA IS KNOW TO BE FREE OF IGNITABLE CONCENTRATIONS. ATTENTION - DANGER D EXPLOSION - LA SUBSTITUTION DE COMPOSANTS PEUT ENTRAÎNER UNE ADÉQUATION À LA CLASSE I, DIVISION 2.

STEP 3 - Front and Back Panels, DB9 Pin-out A B E D C Figure 1. Front Panel G F Figure 2. Back Panel TABLE 1. FRONT AND BACK PANELS A DB9 Female DCE port - see Section 4. B DB9 Male DTE port - see Section 4. C D Pin 3 LED Pin 7 LED Pin 2 LED Pin 8 LED Green, ON, when a TD input (Pin 3) is raised on the DCE port. Green, ON, when an RTS input (Pin 7) is raised on the DCE port. Green, ON, when an RD input (Pin 3) is raised on the DTE port. Green, ON, when a CTS input (Pin 8) is raised on the DTE port. E Power LED Red, ON when power is applied. Power Terminal F Block 2-position, removable (10 48 VDC), see Section 6. G Grounding Lug Chassis ground to earth ground, see Section 5.

STEP 4 - RS-232 Connections TD (Input) TD (Output) SG RD (Output) RD (Input) SG CTS (Output) RTS (Input) RTS (Output) CTS (Input) Figure 3. RS-232 Connectors Connect your RS-232 devices. A DTE device is Data Terminal Equipment ; this includes computers, PLCs, and most devices that are not used to extend communications. Think computer for DTE. A DCE device is Data Communications Equipment ; this includes devices intended to plug directly into a DTE port including modems and devices that extend communications like a modem, such as RS-422, RS-485, or fiber optic converters or radio modems. Think modem for DCE.

STEP 5 - Ground Connection Figure 4. Ground Connection Black Box recommends that you ground the chassis as shown in Figure 4: Connect a grounding wire from the ground lug to a good grounding source. STEP 6 - Power Connection Figure 6. Power Connections Connect the power. Power requirements: 10 to 48 VDC. This repeater draws a maximum of 1.5 Watts. The terminal block will accept 28 to 12 AWG wire.

STEP 7 - Loopback Test / Troubleshooting Figure 6. Connections for Loopback Testing. Black Box recommends: 1. Configure the converter for RS-485 4-wire. 2. Jumper terminals A to C and B to D. 3. Connect a PC to the RS-232 port (see Section 3). Use a DB9 female to DB9 male cable to connect a PC to the DCE port. 4. On the DTE port jumper Pin 2 to 3 and Pin 7 to 8 on the female end of the cable. This loops TD to RD and CTS to RTS. 5. Using hyperterminal or a similar program, connect to the appropriate COM port. Turn off hyperterminal local echo. 6. Transmit the data. The same data that was transmitted should be returned, and the LED indicators should light per the table should light per Table 1 in Section 3.
